“Upstate NY Stargazing” Series At newyorkupstate.com And syracuse.com – Summaries And Links For The Last Few Months

The old adage “if you want to really learn something, teach it” has been in full effect these past few months with the writing of the UNY Stargazing series for newyorkupstate.com and syracuse.com (which don’t combine the comments and shares. You have to go to both!). Firstly, it is excellent practice for anyone doing astronomy outreach to try to capture all of the events and observing opportunities that a new or casual observer might find interesting – while providing enough extra detail to whet the appetites of those reading with a wikipedia tab open (which remains the go-to for astro consistently accurate astronomy information). Secondly, if helps sharpen the editorial blade – such as by not using the word “old” to qualify “adage” when you’re really trying to keep it to 2500 words.

After 11 months of articles, the UNYStargazing template is fairly matured, Stellarium has moved well into advanced topics stage, and the many astronomy clubs that have allowed their public events to be posted have all resulted in an increasingly smooth and, hopefully, informative read.

Having ignored this blog generally recently, here’s the last four months in rapid succession:

– Upstate NY Stargazing in February: Lunar eclipse, Kopernik star party, ‘Dog Nights of Winter’

Friend and Kopernik Astronomical Society member George Normandin provided the eye candy to start the March article, which included a discussion of Messier Objects (such as M31, M32, and M110) still long enough to get the editor’s attention (but it was about Messier Objects and sometimes you have to say stuff). The Lunar occultation of Aldebaran was pointed out to the ASRAS email list by Brad Timerson and then promoted on the CNYO website.

– Upstate NY stargazing in April: Comet hunting and the Lyrid meteor shower

* syr.com/outdoors/index.ssf/2017/03/upstate_ny_stargazing_in…

Brad Loperfido of Revette Studio and the CNYO Facebook Group had an amazing capture of Comet 41P/Tuttle-Giacobini-Kresak, M97, and M108, allowing for a final addition to the Messier Object discussion with the objects that Messier was most interested in finding – comets. The month also included a washed-out Lyrid Meteor Shower peak and a proper shout-out to astronomy.fm.

– Upstate NY stargazing in May: A meteor shower and preparations for the solar eclipse

The first in the series prepping for the great North American eclipse on August 21st of this year, featuring a NASA/SDO/AIA image (our tax dollars at work) and a continuation of the discussion of circumpolar constellations (which will get a full summary in four more articles).

Some Light Non-Science Reading: Circle Templates – Know Your Field Of View!

As appeared in the May 2012 edition of the Syracuse Astronomical Society newsletter, the Astronomical Chronicle.

From the “why didn’t I think of that sooner?” department…

Binoculars are, far and away, the best way to start in observational astronomy (after you have some of the constellations figured out first, of course). The Moon reveals great new detail even at low magnification, the four Galilean Moons of Jupiter are obvious (when they’re not transiting or being “occulted” by Jupiter), all of the Messier objects are find-able (with a little practice and either lots of time or one lucky clear evening in March), and the sky becomes a busy highway of satellites that are otherwise too small to reflect significant light for naked eye viewing. Perhaps less pragmatically but nonetheless significant, the ownership of one simple, easy to produce, easy to use, easy to master piece of paired glassware connects you to the magnification-enhanced world of astronomy begun with Galileo, who used a much poorer quality and lower magnification telescope than those found in Big-Box Stores to forever and disruptively change how Western Civilization (and beyond!) placed itself in the Universe.

That all sounds profound I guess, but you’ve got a book open and are trying to keep track of a flashlight while keeping your arm still as you bounce your head back-and-forth in this really dense part of sky because you don’t know if you’re looking at M36, M37, or M38 in Auriga and you know you’ll NEVER find that part of the sky again. The, if you’ll pardon the expression, dark art of star-hoping is one that absolutely requires practice. More importantly, it requires having a proper frame of reference. I admit that I spent more than a few months with my trusty Nikon Action 12×50’s without ever actually having a handle on just how big the piece of celestial real estate I was staring at was.

It may seem obvious but is something you (well, I) didn’t think to use to your (well, my) immediate advantage. The magnification in the binos does NOT change! You are constantly looking at the same-sized region. This means that you can easily correlate magnification to real estate and know exactly what the limit of your in-eyepiece star-hopping is.

My solution, and one that is generally applicable to all your binoculars (and low-magnification eyepieces in your scope), was to buy an architects circle set. Yes, one of the green numbers with all the holes. If you have one book you’ve committed to (in my case, Sky And Telescope’s Pocket Sky Atlas, but I also have a copy of the Cambridge Star Atlas that hasn’t had its spine properly cracked yet), find some obvious star groupings, see how many of them you can get in your field of view, crack your book open to the right page, and overlay until your circle engulfs only what you see.

Simple! This simple tool dramatically improved my star-hopping aptitude. Keeping with my circumpolar theme this year, using the Sky Atlas and a pair of 12×50’s, I can just barely get the stars Mizar/Alcor and Alioth from the handle of the Big Dipper into the field of view – this corresponds to a 1.1250″ circle…

For the Cambridge Atlas, this same circle is 0.8125″…

I can plot the path to dim or densely-packed objects at leisure by finding bright stars or small groupings and “walking” my view along the path of overlaid circles, always knowing what I should and should not be seeing at any time (minus the odd planet, satellite, Milky Way supernova, etc.).

The same applies to scopes, although you’ll hit that smallest circle quickly (and you’ll find yourself having to flip/invert the image in the piece of paper)! My solution for that was to buy the BIGGEST eyepiece I could find to make sure I’m getting the LEAST amount of magnification. The circles get you to the object, then the magnification draws you in…

Syracuse Astronomical Society President’s Message For March, 2009 – The Messier Marathon Edition

A repost of the original at the Syracuse Astronomical Society website with a brief overview of our upcoming (weather-permitting) Messier Marathon.

Greetings Fellow Astrophiles!

This newsletter comes to you after a short run within the last ten days of almost perfect viewing conditions (ignoring the cold, of course, with the Vesper air reaching the high teens for long durations on a few occasions). We are now officially entering the SAS viewing season, with scheduled New Moon Public Viewing sessions until November (we will see how that plays out) and, we hope, many dark, clear nights in between.

The First Few “Unofficial” 2009 Sessions

The beginning of the viewing year at Darling Hill began this past March 13th, with Observatory Directory Ray Dague and I braving the Vesper elevation and residual ice at the driveway base to check the location and attempt some viewing on what turned out to be a crystal clear night. Despite all efforts (including an outside climb and feet-on-walls pulling. We undertook quite the comical effort just to put eyepieces in), the frozen Observatory roof decided it was too early to “officially” open. We settled for trusty binoculars, plenty of power for Messier warm-up searches and, high above in Gemini, Comet Lulin (which we had to double-check was not NGC 2420).

Board members frozen as stiff as boards.

Additional viewing sessions/board meetings (such as the one captured above on March 20th) were just as clear and just as busy (but included an open Observatory roof!), due in no small part to just how infrequently we in CNY are able to make it outside during the winter for any viewing sessions because of both the cold above and, in the case of Darling Hill, driveway accessibility. For those who wanted to keep track, last year had nine scheduled public viewing sessions and only THREE that were clear enough to be productive. We are already well on our way to a record year and only hope that the gas prices remain low to keep the continual driving to Tully as inexpensive as possible. And, speaking of records…

Messier Marathon

Our early April 2008 Messier Marathon at Darling Hill was a complete overcast wash, with two hours of patience revealing three stars (we used the time to talk about gear, which itself is never a bad thing). It would be difficult to imagine a worse situation that didn’t include precipitation. With cautious optimism for the weekend, we now print out check lists and list object pages in our favorite star charts for MM-2009.

A Brief Overview

We are often visited at the Hill by people who may have heard of the “Mn” designation for an object in the Night Sky but do not know specifically what it refers to. If you’re learning about Messier objects in the context of a website post about the Marathon, then you may think the Marathon to be some kind of celestial relay race between fuzzy patches. Briefly, here are the 5 W-H’s about Messier and the Marathon.

Who: The marathon owes its existence to Charles Messier who, by all accounts (and to the best of my google efforts), never engaged in what he would have simply referred to as “The Me Marathon.” Messier was a famed French comet hunter (the search for comets in the 17th and 18th centuries was THE original “Space Race,” as such discoveries were sure to bring fame and prestige) who, with his assistant Pierre Méchain, catalogued what we know today as the Messier Objects specifically because he wanted to avoid these confusing objects in his cometary searches. Yes, the man who dedicated his life to finding comets is now best known for the catalogue of non-comets he generated. C’est la vie.

What: The Messier Objects are simply a collection of clusters, nebulae, and galaxies that are visible through binoculars and low-power telescopes (and some are naked-eye objects). In effect, they are a collection of the “closest of the bright objects” that one might confuse with a comet, with the “closest/brightest” set including clusters and nebulae within the Milky Way and many galaxies far beyond our spiral arms. As massive, distant, and bright objects, they are stationary in the sky, making them easy for Messier to catalogue in his comet hunting efforts and, for us, making them useful guide posts both for their identification from Constellation markers and for the identification of far fainter objects based on proximity. There are 110 counted Messier Objects but, according to Pierre Méchain himself, only 109 actual objects, as M101 and M102 (the Pinwheel Galaxy) are the result of double-counting (on the bright side, when you’ve found it once, you’ve found it twice!). While the majority of the list goes back to Messier’s time, the last object added, M110, was included in 1960.

Covering the second important “what,” the Messier Marathon is simply a fun way to see how well you know the “photons in your neighborhood… the ones you don’t know you see each night.”

Where: Up! Well, more specifically, up in the Northern Hemisphere. As a French astronomer, Messier’s catalogue contains only objects observable from his Observatory. Accordingly, all 110 objects are visible from Northern Latitudes. That means that (1) a multitude of objects in the Southern Hemisphere that WOULD have made the Messier list are not included because he simply could not point his scope into the ground to look at them and (2) those in the Southern Hemisphere do not engage in Messier Marathons as much as they engage in Messier Sprints, as they have fewer objects to identify (and, the further South they are, the shorter their list is).

The Pinwheel Galaxy (M101 – 102)

When: Members of the Messier list grace our skies all year, with nearly every Constellation visible in the Northern Hemisphere hosting at least one object. Only two things in the Night Sky can obscure Messier objects. The first of these is “whatever else you want to see” that keeps you from looking for the Messiers. The second is the Moon, which can, in fact, obscure the Messier objects considerably (those that are naked-eye Messiers then require binoculars to see, those that are binocular Messiers then require either patience or higher power).

There is one reasonably broad “sweet spot” in the calendar year during which it is POSSIBLE to see every Messier object, with the rotation of the Earth responsible for bringing the entire list to your tripod. This is, of course, only possible because clouds, the irregularity of the horizon (such as our trees to the South and Syracuse to our North), and your ability to remain awake all factor considerably in your success. This time of year is mid-March through early April.

Why: For the reason for the catalogue, see the “What.” For the reason for the Marathon, well, why not? Despite some criticism of the Marathon you can find online, the Marathon provides a way for amateur astronomers to test their memorization of positions in the Night Sky and, important to those of us in CNY, pull out our optics and dust off our notebooks after two or three winter months of missed practice. Again, the Messiers are not simply a set of goals for an observing session, they are invaluable tools as guide posts for the identification of other objects. If the Constellations are “feet” in an astronomical ruler, their associated stars and the nearby Messier Objects serve as the “inches.”

How: An experienced Messier hunter can find the complete set of objects in a pair of 10×50 binoculars. As the goal to some Marathoners is “quantity, not quality,” a low-power pair of binoculars are best for both speed and movement (although your neck will begin to object to objects at your zenith). If I may sneak in a “tortoise and hare” comparison, there’s nothing wrong with finding 20 objects and enjoying the view. You have ALL YEAR to complete your Marathon. They’re not going anywhere!

For the CNY SAS Members: If your goal is to spend from 8:00 pm to midnight outside, your best luck with Messier hunting by binoculars (that is, listing objects that will result in the least amount of neck fatigue) will find you pointing to the south to Orion (M42, M43, M78), Taurus (home of the naked-eye Pleiades, M45, and the Crab Nebula, M1), Canis Major (home of Sirius, the brightest star in the night sky, and M41), Puppis (just to the left of Canis Major and home to M46, M47, M93), and Leo (far to your Southeast, home of M65, M66, and M96).

The North provides a plethora of objects as well, but the glow from Syracuse makes observing a bit more problematic. The Andromeda Galaxy and its Messier companions (M31, M32, M110) in Cassiopeia and the Dumbell Nebula (M76) and Triangulum Galaxy (M33) in Triangulum disappear quite quickly from view after 8:00 pm behind our high northwest tree line, so come early if you want to see them! Waiting out the tree line to our northeast (after about 9:30 pm), Ursa Major and Canes Venatici mark the locations of (from west to east) M82, M81, M108, M97, M109, M40, M106, M101, M51, M63, M94, and M3. As you can see, with limited fatigue on your neck in a pair of handheld binoculars, you can do a considerable amount of checking-off of the Messier objects in very short order and still go to sleep on schedule. I will have my trusty 6″ Newtonian “Stu-Special” in tow, and I’m sure several others will have scopes to complement the Observatory Cave if the weather holds out. Online lists and sky charts abound, but I assume any astronomy book you have will contain sky charts and Messier locations. Don’t forget a red flashlight.

For those who missed them the first time, you might have a chance to see the Andromeda galaxy and her companions again before 6:30 am. For the hardcore observers, you might even be able to cross them off your list twice, although the tree line to our northeast will likely make it quite difficult. We may have to move the party to higher ground!
