CNYO Observing Log: Clark Reservation State Park, 21 August 2015

Greetings fellow astrophiles,

With Perseid Week just behind us, Bob Piekiel and I set up shop for one final Summer 2015 observing session at Clark Reservation. As was mentioned in a Clark Reservation post from last year, it isn’t a great location for heavy-duty amateur astronomers – Syracuse (and its light pollution) lies very close to my hometown of Jamesville (or vice versa, I guess) and even thin cloud cover acts as a dirty mirror to brighten the ground (and sky) around us. For the new observer, however, Clark Reservation is an excellent spot to get one’s feet dewy – it’s close to civilization (and easy to find) and the light pollution wipes out many of the dimmest stars (it probably isn’t far off to say that the sky goes from 2000 to only 400 visible stars thanks to stray city light), making constellation identification significantly easier.

Early attendees listening to the first welcome lecture.

The session started slowly enough around 8:00 p.m. with a small group of attendees present for our introductory observing lecture/white light warning/usual canned schtick. It wasn’t until after we hit the 40 people mark that I found out that this session was mentioned in the Post-Standard paper as a Weekend’s Best. As we hit the near-80 people mark, we both turned up the lecturing knob to keep people informed and entertained as the observing lines cycled through our two scopes. The crowd was excellent, interactive, and very patient.

Every year, I find that some aspect of observing gets a kind of special attention that then becomes part of session dogma (past years being the focus on the hiding of smartphones and flashlights, the very deliberate explanation of how to (and how not to) observe through the scope, and the emphasis on the circumpolar constellations as the best way to get into seasonal constellation identification). The purposes of each of these is, simply, to simplify the session for the attendees (call it a “crash course” in observing). This year, it’s been observation by way of a “hierarchy of observables” (something that Bob and I both have used often). It goes as such:

Early in the evening (including before sunset), non-solar observers have the Moon in all its grandeur (itself possibly the best observable there is for amateur astronomy). While all of the classical planets (Mercury, Venus, Mars, Jupiter, and Saturn) can also be observed, they require a little more time to get to the point of being interesting. Maybe 20 minutes after sunset. By the time that Vega, Arcturus, Deneb, Antares, and Altair are visible (usually coincident with the planets), the most prominent double stars in the sky are visible enough for decent magnification (here, specifically mentioning Albireo in Cygnus and Mizar and Alcor in Ursa Major). Another 20 minutes later, the brightest Messiers are visible – specifically M57, the Ring Nebula in Lyra and M13 in Hercules. 20 minutes later, some of the dimmer Messiers become (just) observable – here, the Andromeda Galaxy (M31 and M32) in Andromeda, and M27, the Dumbbell Nebula in Velpecula. 20 minutes later (so we’re now 80 or so minutes after sunset), the Messier gates flood open and one can begin to make out more objects than can usually be gotten through with a +40 crowd in 2 hours anyway.

Add to this list the ISS, Iridium Flares, random other satellites, a few shooting stars, and some of the detail of the Milky Way inside of Cygnus and down to as much of Sagittarius as the tree line will allow, and you’ve (hopefully) gone a long way to introducing a brand new observer to some of the very best sights available in the nighttime sky (with the above list obviously biased towards the Summer and Fall skies).

To the list above (with only Saturn and Neptune in the planetary observing list), we added at least two meteors (one in the right direction for a Perseid, one not) and a dimmed, by still present, Milky Way band. The lecturing itself didn’t stop for the entire two hours, and we were thankful for the questions that kept us (and others around us) occupied.

With the end of Summer in sight, part of CNYO’s yearly outreach will now include more library lectures and, of course, Bob’s monthly sessions at Baltimore Woods. Stay tuned for event announcements!

CNYO Observing Log: Perseid Week @ Marcellus Library, Baltimore Woods, Beaver Lake, and Green Lakes, 11 – 14 August 2015

Greetings fellow astrophiles!

2015aug25_two-moons-hoaxThis was, far and away, the busiest and best-attended Perseid Meteor Shower week in my history as a CNY-residing amateur astronomer, ranking third overall in public interest behind a Darling Hill Observatory session for the closest approach of Mars in 2003 (the origin of that completely useless meme about Mars and the Moon appearing the same size this (and nearly every one since 2003) August) and the Transit of Venus event held along the Armory Square Creekwalk back in 2012. I would argue that a large part of this local interest (as pertaining to CNYO events, anyway) was due to the efforts of Glenn Coin at syracuse.com in keeping science (and, specifically, space science) in the local paper/websites. His articles following the days approaching, as well as the instigation of we locals to take another shot or two at seeing anything on alternatively partly-cloudy nights, can be found at the links below:

* 6 Aug – Catch the Perseid meteor shower at Baltimore Woods viewing party (by Emily Nichols)

* 10 Aug – Perseid meteor shower: What’s the best night to see it in CNY?

* 12 Aug – ‘Amazing’ Perseid meteor shower: When, where and how to see it in Central NY

* 12 Aug – Perseid meteor shower update: CNY skies should be mostly clear for peak

* 13 Aug – Miss the Perseid meteor shower last night? Try tonight

* 13 Aug – Perseid meteor shower: Watch video of amazing display above the Finger Lakes (by Lauren Long)

Our continued thanks to Glenn Coin and syracuse.com for covering the big yearly astronomy events!

Solar Observing Session At Marcellus Free Library, August 11th

2015august25_marcellus

sunspots_1024_20150811Our Perseid week actually started in the daytime, with a Solar Observing Session run by Bob Piekiel as part of a How-To Festival at Marcellus Free Library on Tuesday, August 11. Like the Sun itself, the Sun’s importance in irradiating comets as they pass into the inner Solar System and melt enough to leave the trails of cosmic debris that become our yearly meteor showers cannot go unnoticed. This session featured Bob’s Coronado 90 mm H-alpha scope, a small Baader’ed refracting scope, and Christopher Schuck’s Coronado PST. Over the course of about 90 minutes (from the session start to the Sun slipping behind the high tree line), we had about 25 people cycle past the scopes to observe numerous medium-sized prominences and a reasonably clear Sunspot 2396 (click the image at right for a larger view from NASA/SOHO).

Besides the continuous dialog about all things solar, more than a few attempts to capture images through the scopes were had. While smartphones are not the ideal gear for accomplishing this (due to both the difficulty in proper placement and the relative sensitivity of the sensors to monochromatic light (in our cases, the dark red H-alpha band)), Chris did manage a pic that included multiple prominences, one power line, and the ever-constraining tree line (below).

A Three-For: Baltimore Woods (Aug. 12th), Beaver Lake (Aug. 13th), and Green Lakes (Aug. 14th)

Bob and I handled scope and lecture duties for the three peak Perseid nights, hitting well-separated locations and a few overlapping attendees. As all three sessions were nearly identical in their content and observing targets, I’ll briefly summarize the unique aspects of each event before giving the combined (and nearly identical) observing lists.

Baltimore Woods (August 12th)

With the best time for the Perseids predicted to be between the late evening of the 12th and 13th, Baltimore Woods Nature Center was predictable busy. Attendees began to arrive around 8 p.m., with total attendance maxing out at about 65 people (and the parking lot itself maxing out before that). With an introductory lecture and white light warning provided, the entire 8:30 to near-11:00 p.m. session only included three shooting stars. Two were moderately bright (and fleeting). A third, the best of all three days, hit atmosphere above a large set of clouds, yet was bright enough to light the clouds like a green-twinged lightning bolt.

2015august25_baltimorewoods

Bob Piekiel and the calm before the storm.

The evening itself turned out mostly cloudy, providing just enough open pockets of dark sky for views of Saturn, a few Messiers, some Constellation touring, one ISS pass, and the three observed meteors that graced the skies that night. Cloud cover became all-consuming just after 10:30 p.m. and we packed up and were gone by 11:00 p.m.

In the interest of trying to catch at least one Perseid by photo, I trekked out to Cazenovia Lake around 4:00 a.m. in 30 minutes of trying, I managed only a single shooter (in the image below, it looks like a white arrow (at bottom) pointing to some dim objects).

Beaver Lake Nature Center (August 13th)

CNYO’s official seasonal Beaver Lake Nature Center session was greatly simplified by having the Baltimore Woods session the night before (meaning Bob and I could attend both sessions with no overlap). With the session moved from the Beaver Lake rotunda to the overflow parking, we found ourselves in a darker, lower tree-lined, and easy to arrange location (meaning we may request that all future sessions be held in the same spot!). Beaver Lake skies were not much clearer than Baltimore Woods, but the waits between observables was shorter and our ability to cycle through objects and attendees was improved. With additional announcements on syracuse.com, the final Beaver Lake count was five meteors and about 75 people from our 8:30 introductions to 11:00 p.m. pack-up.

Green Lakes State Park (August 14th)

2015august25_greenlakes

Upcoming festivities announced during our session.

Our Green Lakes State Park session in July peaked near 120 people (some for the stars, some for the s’mores), which is quite a crowd for 3 scopes! Despite the predictions of clearer skies than previous days and generally excellent evening weather, the August session capped itself at about 70 people (with a bunch of them being young amateur astronomers who packed it in early, leaving a smaller group of about 15 to stay until our 11:00 p.m. Ending to pick off several Messiers after Saturn slid behind Green Lakes’ high southern tree line. Going solely by “ooh-and-aah” statistics, Green Lakes attendees may have seen a total of 5 Perseids (none rivaling the one from Baltimore Woods, but easily seen in the mostly clear skies above).

Observing List (More Of The Summer Same, And For Good Reason)

As has been discussed many times on this website, the importance of introducing new observers to easily observed and described objects cannot be understated. The hunt for dim NGCs and equally dim Messiers is always worthwhile with sufficient time and clear skies, but the brand new observer (arguably) benefits more from prominent views of objects such as the Moon, M13 in Hercules, Alcor and Mizar, M57 (the Ring Nebula) in Lyra, The Andromeda Galaxy (M31), and the bright visible planets each evening. These objects are easily seen by anyone approaching the eyepiece and can be used to give new observers a kind of “upper limit” on their expectations of what a scope is capable of magnifying from ground level. Amateur astronomy, like chess, can become a lifelong training in subtlety. That said, the mechanics are easy to learn by slowly introducing the many kinds of players.

With two scopes and +60 attendees at each session, we were definitely limited in our observing variety simply by the lengths of the lines behind each scope. That said, we were able to give all of the patient attendees some great views of the night’s best for each Perseid session. The short list of objects is below (listed according to the order in which they’re observable as the skies get darker and darker):

* Saturn (our bright planet for the Summer and Fall)
* Alcor and Mizar in Ursa Major, Albireo in Cygnus, Herschel’s Garnet Star in Cepheus
* M13 (globular cluster) in Hercules, M57 (The Ring Nebula) in Lyra
* M27 (The Dumbbell Nebula) in Velpecula
* M31 (The Andromeda Galaxy) and M32 (one of its two satellite galaxies) in Andromeda
* M51 (The Whirlpool Galaxy) in Canes Venatici

In closing, we had an excellent week-long turnout for the sessions and are grateful to everyone who came out to make this a busy Perseid show. We hope all of the new faces on our meetup and Facebook pages keep track of upcoming events – and we hope to see your dark, featureless outlines at another 2015 session!

CNYO Observing Log: Clark Reservation And Baltimore Woods, 18 July 2015

Greetings fellow astrophiles!

Bob Piekiel and I have continued to make the most of the Summer for hosting observing sessions. While the Sun is good anytime, the Summer Nighttime Sky certainly makes for a worthy complement to our Winter sessions. Instead of crisp, clear (and cold!) conditions and close-ups of some of the most impressive objects in the Nighttime Sky (everything in Orion alone is worth dressing up for), we trade boots for sandals (or less), slap on the bug spray, and scour into the heart of the Milky Way for a host of fine objects to our zenith and points south. As Summer weather is also easier to brave for most, we enjoy larger turnouts and introducing others to the greater outdoors.

Clark Reservation, 18 July 2015, 1 to 3 p.m.

sunspots_1024_20150718

The Sun from Saturday, 18 July 2015 (from NASA/SOHO)

While the Sun is always busy, those phenomena which causes us to spend beaucoup bucks on equipment were in short supply on the surface that afternoon, with tiny-ish sunspot 2386 the only significant feature to scout around. The presence of Bob’s Coronado H-alpha, He, and CaK scopes did noticeably open up the feature window for some of the more subtle objects.

2015august2_solar_group_IMG_8230

The whole session ran a hot two hours. About 15 people made rounds to the scopes, with a few people making second rounds (some to see again, others returning after some of the clouds had moved on for their first viewing). As a true testament to Syracuse weather conditions, we went from blue sky to heavy cloud cover to a quick sprinkle and back to blue sky in a 10 minute window at 2:30.

Baltimore Woods, 18 July 2015, 9 to 11:30 p.m.

Unfavorable conditions Friday night made for a Saturday observing double-feature. We had some hold-over from a Baltimore Woods concert (featuring Joanne Perry and the Unstoppables) that ended at 8:00 p.m. (while it was still far too bright to do any observing. Even the Moon was a tough catch) and a patient wait for, um, one person’s mirror to warm up after a heavily A/C’ed drive from downtown Syracuse.

2015august2_venus_moon_IMG_0036

Venus and the Moon caught just at the tree line. The elongated view of Venus is not an exposure artifact (1/200th second at that), but is because Venus was, at that time, a medium-thin crescent. Click for a larger view.

The evening turned out excellent for Public Viewing. Venus and the Moon (see above) were an early, close catch due to the high summer tree line (Jupiter was too far below the tree line by the time it was dark enough to be interesting in a scope, although Bob did get one quick view of it earlier after aligning his Celestron Nexstar), after which Saturn, Antares, and Arcturus were the next catches.

Despite a band of slow-moving clouds to the South early on that threatened quite a bit of celestial real estate, the skies cleared nicely for a full 2.5 hours of observing. With a healthy variety of kids and adults in attendance, there was as much discussion as their was observing. A few of the kids in attendance knew just enough to know what they wanted to see, making for a fun game of “stump the scope owner.” My observing list through my New Moon Telescope 12.5 Dob was as follows:

* Saturn – Several times for several waves of attendees, and the Summer and Fall’s highlight planet.

* Albireo in Cygnus – Part 1 of a “test your retinal cones” survey, with everyone able to get at least a little orange and a little blue out of this binary.

* Zubeneschamali in Libra – Part 2 of a “test your retinal cones” survey. Bob, er, found a way to get 100% agreement on the apparent green-ness of this star (a much better percentage than at our Green Lakes session), courtesy of a particular screw-on filter.

* Herschel’s Garnet Star in Cepheus – Part 3 of a “test your retinal cones” survey. The Garnet Star has become a favorite for 2015 viewers, as the dark amber/red color jumps out to everyone (no subtlety, or filters, to be found).

* Alcor and Mizar in Ursa Major – A binaried binary, with one binary itself binary of binaries. Not only do you get to stare at six gravitationally-bound stars, but you get to explain the differences between optical, true, and spectroscopic binaries with a single shining example.

* M57, The Ring Nebula in Lyra – Old amateur astronomers pride themselves in being able to discern all kinds of detail from dim, fuzzy objects. I tend to talk down the impressiveness of some objects to make sure new viewers spend a little extra time pulling detail out (we’re not Hubble, after all). Everyone present for the Ring saw the donut easily at low magnification and were happy to spend extra time giving another, even fainter look at high power (which made for a great part of the whole session in my book).

* M13, The Globular Cluster in Hercules – Second only to Saturn in “woah” moments, M13 never disappoints visually. After you add a little bit about its size and history, several people insisted on taking another, more informed look at it.

* M51, The Whirlpool Galaxy in Canes Venatici (but just-just off the handle of the Big Dipper in Ursa Major) – Just off the last handle star of the Big Dipper. I had one request to see something outside of the Milky Way. With the Andromeda Galaxy in the direction of Marcellus and Syracuse (and the night already getting long for many of the kids in attendance), I tested some eyesights (and imagination) on this faint pair of galactic cores in collision.

* To that list we added one decent shooting star, just enough of the 300 billion other stars in the Milky Way to make out its cloudy band through Cygnus and down to Sagittarius, and one timed Iridium Flare (see below).

2015august2_iridium_IMG_0048

An 11:09 p.m. Iridium Flare caught below the bright star Arcturus (for the record, caught at its brighest first, so the satellite is going from the left to the right in the image). Click for a larger view.

August has rapidly become a busy month for observing, with several sessions planned around the Perseid Meteor Shower. Keep track of the website for whether/weather announcements. We hope you can join us!

CNYO Observing Log: “Stars And S’mores” At Green Lakes State Park, 10 July 2015

Greetings, fellow astrophiles!

I’ve had few chances to provide write-ups of observing sessions in 2015 due to CNY skies not agreeing with we amateur astronomers. Fortunately, Bob Piekiel’s yearly 2015 Green LakesStars and S’mores” Summer Session (on the books for 6 months now) landed on an excellent summer night, providing a large crowd some excellent views of some (sadly, not all) of the Solar System’s best sights.

2015july13_greenlakes

There were roughly 120 people in attendance at the start of the session (by the car/people count of the Green Lakes staff. They estimate 3.5 people per car on average, which sounds like quite a mess in the back seat), making this the largest public CNY session I’ve attended since the Transit of Venus in 2012. To Bob’s SCT and my NMT 12.5” Dob was added guest attendee and the IOTA’s own Ted Blank with his (I’m pretty sure, anyway) Orion 120mm ST Refractor. We had one last work-in-progress scope in attendance with the arrival of fellow CNYO’ers Kirk Frisch (his work-in-progress) and Chris Schuck. As usual, the setup of the scopes cut into our collective s’mores time.

Bob had already aligned his SCT and started close to 8:00 p.m. on the viewing of Venus after a quick welcome and safety lecture. I had someone with great eyesight point out Venus near my scope, after which the line behind my Dob hit +50 people. Sadly, with a +50 person line at each of the scopes and all pointed at Venus to give the attendees that view, you take quite a bit of time to show the planet to everyone (and for the motor-less scopes, additional time re-nudging Venus back into the eyepiece. Stupid Earth rotation…). For us, that meant that Jupiter, the next to appear after sunset, was already obscured in the high tree line to the West of the Green Lakes field. Bob had a short-but-heroic catch between branches, but Ted and I were left to wait for Saturn.

Another search by the same woman at my scope (someone had a big piece of carrot cake earlier, I guess) pointed out Saturn midway above another high tree patch. We all then spent a good 30 minutes on Saturn, comparing views and encouraging people to spend a little time trying to pull additional detail out – namely, Titan and the Cassini Division. Finally well after sunset, the stars began to then appear behind Saturn, so person #40 had a more engaging view than person #1.

Venus and Saturn viewing for the whole group took about an hour, after which the youngest members of the crowd headed home and a few others showed in time for some non-planetary viewing that went until about 11:00 p.m. My observing list for the night (a recurring theme for all of the Summer public viewing sessions) was as follows:

* Saturn and Venus

* Albireo in Cygnus – a Summer favorite to show people that stars are actually quite colored when you find the right ones (and binaries make it all the more interesting)

* Alcor and Mizar in Ursa Major – first as a Naked Eye test for attendees, then on to the discussion of the complexities of a 6-star (!) system

* M57, the Ring Nebula in Lyra – a real standout at near-zenith, as well as a preview of what our own Sun will look like in 5-ish billion years

* Herschel’s Garnet Star in Cepheus – the first of the closers for the evening, showing that some stars are very intensely colored

* Zubeneschamali (?! Let’s go with beta Librae) in Libra – the second of the closers in my scope (at Bob’s request). Some people see this as a faintly green star, which makes it quite noteworthy (Bob and I have decided it’s actually blue-ish instead. According to wikipedia, “There seems to be no generally accepted explanation for why some observers see it as green.” Perhaps someone could do the study to see if these people also see the dress as black and blue).

The Andromeda Galaxy (M31) and M32 – a final view just above the horizon (so all had to stoop low to see into the eyepiece) to take the final 5 attendees outside of the Milky Way. At the risk of starting an argument, I would argue that M31 is best viewed through 25×100 binoculars, giving you the best combination of field of view (this galaxy is six Full Moons across and any significant magnification causes you to miss lots of the trailing starlight around the core) and spiral detail. In fact, M31 is a prime reminder to all that a good pair of binos is a must-have for the dedicated observer.

Those interested in some additional summertime viewing are welcome to join us at Bob Piekiel’s Baltimore Woods session this coming Friday, July 17th (18th as the weather-alternate) and solar session at Clark Reservation on Saturday. Check cnyo.org on Friday afternoon for an official announcement. We hope you can join us!

CNYO Observers Log: Green Lakes State Park Solar Session (7 March 2015) and Monthly Baltimore Woods Session (13 March 2015)

Greetings fellow astrophiles,

A quick observing log combining two recent events hosted by Central New York’s own Bob Piekiel. As everyone who’s been local all winter knows, conditions were less than ideal for lots of observing. For those sessions that cloud cover (and snow) didn’t ruin, the Arctic Chill that hit CNY in the middle of February really did a number on even the most determined observers.

Solar Session – Green Lakes State Park – 7 March 2015

2015march19_solarsession

Having put off and re-put off a solar observing session at Green Lakes State Park bus to lousy conditions, the powers that be wanted to go forward with a session on Saturday afternoon, March 7th. With H-alpha and Baader’ed scopes in tow, Bob (and I helping run the Baader’ed scope) hosted a session in the parking lot behind the main building at Green Lakes. Over the course of about 90 minutes, perhaps 10 good minutes of observing were had. Clear skies to the East couldn’t be coaxed to shift West and the upcoming mild snow storm that afternoon even provided some advanced warning. Still, about 10 people either showed specifically for the solar or made their way off the skiing path to take in a few sights of our nearest star.

2015march19_sunspots_1024_20150307The Sun itself wasn’t particularly busy that afternoon, with a major sunspot region having just fallen off the Sun’s edge, leaving a small speck of dark spots just within scopesight (see the March 7th image at right from NASA SOHO. Click for a larger view). As with all sessions, the observing was complemented by good introductory astronomy discussions and direction to the CNYO site for upcoming events (including upcoming solar sessions).

For those keeping additional track, the Sun did provide quite a show over the past few days in the form of fantastic aurora after an X-class solar flare fired up ionization in our atmosphere. For those looking for a gallery of what everyone by Central New Yorkers (it seems) saw over this past St. Patrick’s Day, I encourage you to let google do the work for the following image search: solar storm st. patricks 2015.

Baltimore Woods Monthly Session – 13 March 2015

2015march19_baltimorewoods

A panorama from the Baltimore Woods Session start. Click for a larger view.

A decidedly more fruitful session was had in the thawing parking lot of Baltimore Woods on Friday, March 13th. This evening was also first light for 2015 of my 12.5” NMT Dob (Bob’s SCT having already seen action with a few observing sessions this year). The sky (mostly) did not disappoint! Jupiter and Venus were easy and excellent targets, Mars was at the horizon at session start but still observable (Uranus having slipped too low to see), and a dozen eager observers attended to take in the sights. The only real letdown for the evening was the persistent cloud cover that obstructed all of Orion throughout, giving only a few passing views of the Orion Nebula. To Jupiter, Venus, Mars, and the Orion Nebula (sort of), a very double-centric crowd were treated to views of the double cluster in Perseus, Alcor and Mizar in Ursa Major, and Castor (a sextuplet star system that resolves to a bright binary pair) and Pollux in Gemini. Cloud cover was just persistent and wide-ranging enough to make galaxy views all but impossible, making the whole session a real hopscotch survey of the brightest available at the time. After a solid 80 minutes of observing, we finally packed up with plans for the next sessions made.

For those wanting to check out one of Bob Piekiel’s many events this year, please see his calendar on the CNYO website. We hope to see you!
