CNYO Observing Log: Baltimore Woods, 22 March 2014 (And An Erigone Summary)

Greetings fellow astrophiles!

The often-announced (on this site, anyway) Regulus occultation by asteroid (163) Erigone on the morning of March 20th was a near-wash (no rain, but plenty of cloud cover), with only a few messages being passed around at midnight to see if anyone was even going to try for 2:00 a.m. That said, the International Occultation Timing Association (IOTA) got lots of good press and, with luck, a similarly notable occultation will occur to catch other eyes and instigate the IOTA to prep another big public recording effort. Those who want to relive the non-event can watch the Slooh Community Observatory coverage in the youtube video below.

Then, two days later, Bob Piekiel with his Meade C11 and I with my New Moon Telescope 12.5″ Dob treated two couples at Baltimore Woods to the kind of crystal clear and steady skies you read out but usually never have the good fortune to be out for. With the late March and early April temperatures beginning to melt the high hills of ice and snow around all the big parking lots in the area, the Baltimore Woods setup was a bit solid, a bit slushy, and quite dirty. Our four-person audience arrived early in time to watch the clear skies darken and Jupiter, Sirius, and Betelgeuse first appear in the South/Southwest sky. For the next 90 minutes or so, the observing list included Jupiter (several times at several magnifications, both early in the evening and after the skies had sufficiently darkened to bring out more detail), the Pleiades (M45), the Beehive Cluster (M44), the Orion Nebula (M42), Alcor and Mizar in the handle of the Big Dipper, the Andromeda Galaxy (M31) and its prominent satellites (M32 and M110) very low on the horizon (very likely our last catches of our sister galaxy for several months to come), and even M82 to say that we had, at least, seen the location of the recent supernova (if not a last few photons from it).

In an attempt to help someone remember as many constellations as possible at the Liverpool Public Library lecture a few weeks prior, I retold one of the more memorable tales of the winter star groupings of Orion the Hunter, Taurus the Bull, Canis Major (the big dog), Canis Minor (the little dog), and the Pleiades that I picked up from the excellent Dover book Star Lore: Myths, Legends, and Facts by William Tyler Olcott (which you can even read and download for free in an earlier form at archive.org).

Long story short, the Pleiades (also known as the Seven Sisters or the Seven Virgins) were the target of Orion’s rather significant attention, so much so that in his last run to them, the ever-invasive Zeus placed an equally significant bull in Orion’s path, leaving Orion and his two dogs (Canis Major and Canis Minor) stuck in their tracks. As is apparent from the images below, these four constellations (and one star cluster/Messier Object) are all tightly spaced in the Winter Sky. Better still, the end of Winter even finds these constellations standing on the horizon (instead of upside down in morning Autumn skies), making the picture all the more easily seen. As Orion is second only to the Big Dipper in terms of ease-of-seeing by practically everyone (raised in the tradition of Western Constellation arrangements, anyway), it’s the start constellation from which to find the other three. Canis Major is easily found by its shoulder star Sirius, the brightest start in our nighttime sky. Canis Minor is a leap from Sirius to Procyon, also a prominent star. Taurus the Bull is easily found by its head, the local star cluster known as the Hyades, and its orange-red eye, Aldebaran. The small sisters lie within the boundary of Taurus in a cluster that to the slightly near-sighted might just look like a fuzzy patch (but which, in binoculars, reveals numerous tightly-packed stars).

After packing up around 9:30 (about when the temperatures began to drop precipitously), I managed a single long-exposure image with my Canon T3i of the region above – quite possibly my last good look at the most famous Winter grouping until they appear again in the morning Autumn skies.

CNYO Observing Log: Baltimore Woods, 27 September 2013

Greetings fellow astrophiles!

The September 27th Baltimore Woods session was notable for several reasons. On the down side, my drive to Marcellus through Fairmount was delayed when a minivan with far too many large dogs in it had one of its automatic windows dropped down to the delight of an ejected dog that bounced off my driver side door (my non-astro thought for the day – if your pets are your children, please use the child safety options built into your very modern vehicle!). On the up side, for the first time since March, a Baltimore Woods session started at 7 p.m. The skies were dark enough to begin seeing the brightest stars with ease and cold enough to freeze out the many bugs that frequent the BW Nature Center.

Attending scopes included Bob Piekiel‘s massive 16″ Meade GOTO (with some included heavy lifting by the two of us to get it set up and torn down), Larry Slosberg’s 12″ New Moon Telescope, and my 12.5″ NMT Dob (herein referred to as “Ruby”). A fourth scope appeared early in the evening with the first attending family, but ended up not getting too much use. Despite being a bit worse for wear, their “retail store” Stratus 60mm refractor scope surprised the owners (and kids) with a good view of a distant cellular tower and a fuzzy but noticeably “half-moon cookie” Venus (whatever description works is fine with me).

The final size (25ish) of the crowd (and the number of first-time attendees) dictated the observables for the evening, with all of us sticking mostly to bright, easily identifiable objects. As for our local neighborhood, the good news was that more than half of the planets were out for the evening (counting the views of Earth). The bad news was that Venus and Saturn set early (both due to the time and the high trees along the Western horizon), leaving the very distant Uranus and Neptune as targets for later-night observers.

As has been my standard procedure, I picked one object from my standard list of “kinds of” objects so those at my scope would be sure to get a sampling of the types of objects we amateur astronomers look forward to looking at. My list included:

* (Hopefully) One Planet – From my (scope’s) vantage point, Venus and Saturn were impossible catches behind large trees. Neptune and Uranus were, for the entire viewing session, nestled within the glow of Marcellus (and Syracuse beyond), so I didn’t even bother attempting to find them. Bob, however, had at his disposal a massive GOTO, so the gathered crowd was able to take in at least one of the two distant planets (making them part of the way-less-than-1% of the entire planet who can claim the same).

* One Star – At Bob’s request, I gave special attention to Herschel’s Garnet Star (mu Cephei) in Cepheus. One of the real benefits of magnification through good optics (or long-exposure photography) is the appearance of color in many stars that are otherwise just too slightly colored to be noticeable to Naked Eye observers. While the different colors of the binary star Albireo are generally obvious to most people, the Garnet Star jumped out to everyone through every eyepiece as a very orange star. This red supergiant, affectionately known to some as Erakis, is BIG. Those who have seen the image below in one of our CNYO library lectures…

The scale of familiar objects in our vicinity (click for the wikipedia version).

Will recognize Mu Cephei as the third star from right (in the “Big Block” 6) in the bottom of the image. Our own Sun peters out in Block 3. If a super race of aliens were to swap out our Sun for the Garnet Star, the outer edge of its plasma would engulf Jupiter and either engulf or roast Saturn. Big. Not only big, but old to boot. Mu Cephei is what is known as a “carbon star,” one that has nearly exhausted its helium (which is produced from all the fusion of hydrogen, which it then exhausted quite some time ago) and is now producing carbon in the star’s core. The near-exhaustion of the star’s fuel means that it’s likely only a few million years from going supernova (somewhere between a finger snap and ringing wine glass in cosmic terms) and is currently identified as a variable star for its subtle and erratically changing brightness.

Mu Cephei, Cepheus, and surrounding constellations.

As you scour Cepheus some evening, do take the Garnet Star in. If you’re scanning randomly along the bottom of the barn, you can’t miss it!

* One BinaryAlbireo in Cygnus remains an easy favorite. Everyone saw Albireo A as slightly orange or yellow, while Albireo B appeared as slightly to “clearly” blue (clearly a demonstration of the importance of dark adaption and cone sensitivity in the retina). One point of interest is that we’re not entirely sure of Albireo is an optical binary (the two just appear close, but one is much farther away than the other as projected onto our two-dimensional sheet of the Night Sky) or a gravitationally-bound binary pair. If gravitationally-bound, the two are likely far from one another, with the orbital dance occurring over 100,000 or more years.

* One Open Cluster – The Double Cluster (Caldwell 14) in Perseus

* One Globular Cluster – The ever-obvious M13 in Hercules

* One Nebula – The Veil Nebula in Cygnus – typically, this would be considered one of the less-easy objects for a new observer to make out. Through an OII filter, however, the wispy-ness jumps out and new observers, with a little patience, can even see the curvature of each fragment well enough to know where the Veil must be radiating from.

* One Galaxy – M31, The Andromeda Galaxy in Andromeda (and M32 and M110), which were easy for all to spot with a little scope nudging.

As has become the norm recently, I packed up Ruby around 9:30 p.m. and pulled out the Canon T3i and tripod for an extended session of scope-less astrophotography. Three highlights include a very discernible Milky Way, complete with Great Rift, from opposite the direction of Marcellus…

And a quite decent view of the varied objects in the vicinity of the constellation Perseus (in the pocket between the two trees and closer to the left tree), including the components of the Double Cluster, NGC 884 and 869 (the fuzzy splotches at the base of the small necklace – 1/3 over from the left edge and 1/4 down the image).

I packed it in around 10:00 p.m. in great anticipation! Within the glow of Marcellus lay the Pleiades (M45) and just a hint of its closer cousin the Hyades in the head of Taurus the Bull. These objects have likely served as markers for many millennia that the clear, dark, steady, and uncomfortably cold night skies of winter approach.
