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


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.

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

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!

CNYO Observing Log: The Winter Of Lovejoy – Green Lakes, Jamesville Beach, And New Moon Telescopes HQ – January 9 to 14, 2015


Comet Lovejoy imaged on January 10th by the ever-impressive CNY astrophotographer Stephen Shaner. From his CNYO Facebook Group post: Last night was the first in over three months it was clear enough to shoot, but it worked out well because Comet Lovejoy is at its peak. Here’s a quick process of about 40 minutes of exposures between 8-9 PM as it crossed the meridian. FOV is roughly three degrees. Distinct pale green coma in the eyepiece but unable to make out a tail or see it naked eye.

The 2015 skies are going to be full of comets. Well, at least six, to be exact, that will be either naked eye- or binocular-visible. That’s still quite a few to those keeping track! The amateur astronomy community has taken heroic efforts to scientifically identify and track new comets in the last, say, 400 years. The rise of, for instance, the Panoramic Survey Telescope & Rapid Response System (or panSTARRS) as a method for finding and tracking both comets and near-earth asteroids (or, lumped together, “objects,” for which you might hear the abbreviation “NEOs”) has greatly increased the number of accounted-for fuzzy objects in our fields of view (and provided us a giant leap in our existential risk assessment infrastructure to boot). Quite simply, we’ve more + better eyes on the skies, meaning we’re bound to continue to find more and more comets and asteroids. You can even subscribe to NASA twitter feeds that announce the passing-by of these hopefully passers-by (see @AsteroidWatch and @NasaNEOCam).

The discovery of NEOs may or may not qualify as a modern John Henry-ism, as amateur astronomers are still discovering objects at a decent pace thanks to improvements in their own optics and imaging equipment. Comet Lovejoy, C/2014 Q2, is one such recent example discovered by famed modern comet hunter Terry Lovejoy (who has five comets to his name already).

Comet Lovejoy And More In CNY

Comet Lovejoy has made the winter sky that much more enjoyable (and below freezing cold that much more bearable) by reaching peak brightness in the vicinity of the prominent winter constellations Taurus and Orion. Visible soon after sunset and before the “really cold” temperatures set in (after 10 p.m. or so), Lovejoy has been an easy target in low-power binoculars and visible without equipment in sufficiently dark skies. Now on its way out of the inner solar system, its bright tail will shrink and its wide coma (that gives it its “fuzziness”) will disappear as the increasingly distant Sun is unable to melt Lovejoy’s surface ice. Those of us who dared the cold, clear CNY skies these past few weeks were treated to excellent views, while the internet has been flooded with remarkable images of what some have described as the most photographed comet in history (a title that will likely be taken from it when a few other comets pass us by during warmer nights this year).

The first observing session around Syracuse this year happened at Green Lakes State Park on January 9th. Bob Piekiel, one of CNY’s best known and most knowledgable amateur astronomers, had his Celestron NexStar 11 in the parking lot behind the main office, which was fortunately kept open for attendees hoping to warm up between views. To Bob’s C11 was added my Zhumell 25×100’s, providing less magnification but a wider field of view to take in more of the comet’s core, tail, and nearby stars.

The Friday night skies were only partially on our side, offering a few short-lived views of the Orion Nebula and Lovejoy. Jupiter was just bright enough to burn through some of the cloud cover to our East, giving us slightly muddled but otherwise decent views of it and its four largest satellites for about 10 minutes. By our 9 p.m. pack-up and departure, the skies were even worse – which is always a good feeling for observers (knowing they didn’t miss a chance for any additional views by packing up early).

The night of Saturday, January 10th turned into a much better night for observing, offering a good opportunity for some long-exposure images to try to capture Lovejoy just past its luminous prime. The following image was taken from one of the parking lots at Jamesville Beach – the same spot where Larry Slosberg, Dan Williams and I observed the nova in Delphinus. Light pollution aside from the 30 second exposure, the brightest constellations are clearly visible and a fuzzy, bright green star is clearly visible in the full-sized image.

The imaging continued in Marcellus on January 10th, with Bob Piekiel producing a zoomed in view of Lovejoy.

As with all astronomical phenomena (excluding solar viewing, of course), the best views come from the darkest places. A third Lovejoy session was had up in West Monroe, NY on Wednesday, January 14th with fellow CNYO’er Ryan Goodson at New Moon Telescopes. Putting his 27” Dob to use, the green-tinted Lovejoy was almost bright enough to tan your retina. With dark skies and no observing line, we then attacked some subtler phenomena, including the Orion Nebula in Orion, the Eskimo Nebula in Gemini, and the Hubble Variable Nebula in Monoceros. The images below are our selfie with Lovejoy and the best of Winter, a snapshot near the zenith (with Jupiter prominent), and the Northern sky (click on the images for larger, unlabeled versions).

A Clothing Thought…

As we can all attest to, the nighttime temperatures this month have oscillated between bitterly cold and painfully cold. The pic of my Element’s thermometer at my midnight departure from West Monroe read -12 F (and the tire inflation warning light stayed on until I hit 81 South), yet with the exception of the tips of my toes, I wasn’t very bothered by the cold.


2015jan22_nmt_layersIt’s one of the cold realities of amateur astronomy – you never realize how cold it can get outside until you’re standing perfectly still at a metal eyepiece. The solution is as old as the sediment-grown hills – layers! The top half of my outfit for the evening is shown below, featuring six (yes, six) layers from turtleneck to final coat. My bottom half featured three layers that decorum permits me from showing here. For those wondering how the blood still flows below the belt, the answer is simple – buy yourself an outer layer two or three sizes larger than you usually wear. In my case, my outer coat’s a bit baggy and my outer pants are a very tightly-meshed pair of construction pants with a 40” waist (from a trip to DeJulio’s Army & Navy Store on Burnet Ave. in Syracuse).

And don’t worry about color coordinating. The nighttime is the right time for the fashion unconscious.

CNYO Observing Log: Beaver Lake Nature Center, 18 September 2014

Greetings fellow astrophiles,

After a double wash-out for our scheduled August 8/15 event, CNYO made a triumphant return to Beaver Lake Nature Center for one last end-of-Summer public viewing session. While the local meteorologists and the Clear Sky Clock predicting clear, dark skies for the entire evening, the observing itself was still a bit touch-and-go until about 9:00 p.m., when the whole sky finally opened up.

Despite a small snafu with the Beaver Lake events calendar (or, specifically, our lack of presence on it for this rescheduled event), we still managed 10 attendees (and passed the word along to several people there for an event earlier in the evening – I’m also happy to report that Patricia’s attendance justified our meetup group event scheduling!). With four CNYO’ers (Bob Piekiel, Larry Slosberg, Christopher Schuck, and myself) and three scopes present (including Bob Piekiel’s Celestron NexStar 11, Larry Slosberg’s 12” New Moon Telescope Dob, and my 12.5” NMT Dob) this was a great chance for several of the new observers to ask all kinds of questions, learn all the mechanics of observing through someone else’s scope, and, of course, take in some great sights at their own pace.

The 7:00 p.m. setup started promising, with otherwise overcast conditions gradually giving way to clearings to the Northwest. That all changed for the worse around 8:00 p.m. (when everyone showed up), when those same NW skies closed right up again, gradually devouring Arcturus, Vega, and any other brighter stars one might align with. The next hour was goodness-challenged, giving us plenty of time to host a Q+A, show the scope workings, remark on the amount of reflected light from Syracuse, and swing right around to objects within the few sucker holes that opened. And when all looked lost (or unobservable), the 9:00 p.m. sky finally cleared right up to a near-perfect late Summer sky, complete with a noticeable Milky Way band, bright Summer Triangle, and a host of satellites, random meteors, and bright Summer Messiers.

As has been the case for nearly every public viewing session this year, all the new eyes were treated to some of the best the Summer and Fall have to offer. These include:

M13 – The bright globular (“globe” not “glob”) cluster in Hercules
M31/32 – The Andromeda Galaxy (and its brighter, more separated satellite M32)
M57 – The Ring Nebula in Lyra
Herschel’s Garnet Star – To show very clearly that many stars have identifiable colors when magnified
Albireo – To reinforce the color argument above and to show one of the prominent doubles in the Night Sky, right at the tip of Cygnus.
Alcor/Mizar – Did you know that Alcor/Mizar is actually a sextuple star system? Alcor is its own double, each in Mizar is a double, and recent data reveals that the Alcor pair is gravitationally bound to the Mizar quartet.

To the observing list was added a discussion of how to begin learning the constellations. As we’ve discussed at several sessions, the best place to start is due North, committing the circumpolar constellations to memory FIRST. For those unfamiliar, these are the six constellations that never set below the horizon from our latitude (Ursa Minor (Little Dipper), most or Ursa Major (Big Dipper), Cassiopeia, Cepheus, Draco, and Camelopardalis (and if you can find Camelopardalis, you’re ready for anything). We’ve even consolidated all of this material into one of our introductory brochures for your downloading and printing pleasure:

CNYO Guide For New Observers

To my own observing list was added a treat thanks to Bob’s perfect position on the rise of the Beaver Lake parking circle, as he managed to catch Uranus low on the Eastern horizon just before we packed up for the evening. Even with Syracuse’s glow dimming the view, Uranus is a clear sight either in a scope (as a slightly blue-green disc) or through a low-power finder scope.


Closing at Beaver Lake (including one low-flyer).

We offer special thanks to the Beaver Lake staff, who were fine with us staying as late as we liked (although we still finished up around 10) and who found *all* the light switches for the parking lot. I suspect our next Beaver Lake event won’t happen until the Spring, meaning we hope to see you at one of Bob Piekiel’s Baltimore Woods sessions during the winter – unless we all get inspired to throw extra layers on and organize another winter observing session somewhere, in which case we hope to see you there as well!
