A re-post from the CNY Observers website (www.cnyo.org).
Caption: 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).

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.

I remember my first foray into Constellation memorization, still the first thing I recommend for anyone beginning in amateur astronomy (primarily for using these imagined creations to memorize the locations of far dimmer objects when you graduate up to binoculars or small scopes, but also simply to develop a sense of, well, the space between these creations as you jump between objects).

Those who’ve ever been told that “there are more fish in the sea…” should be relieved that we only cast our visual nets to the heavens for stars and galaxies, as this most important of animals throughout history is only represented in the Northern Hemisphere by one pair of gilled swimmers tied at the tails.

Of all of the Constellations that have taken human forms through history, Aquarius the Water Bearer may have the most varied professional background. His career peaked early in human history, with the Babylonians identifying Aquarius as GU.LA, their identifier for the god Ea, Ea derived from the Sumerian god Enki. To put that into perspective, the stars of Aquarius have been recognized as a Constellation since, at the very least, 1200 B.C. (the dates of the oldest known Babylonian star catalogues. As these catalogues borrow heavily from Sumerian mythology, we can only assume his actual origins step significantly further back, although records are difficult to come by). His demotion to water bearer comes with his adoption by the Greeks and his inclusion into their mythology, with his aquatic status in Greek mythology traveling, albeit likely by land routes, as far East as India. Then, like a leisure suit-clad Pat Boone on his pre-heavy metal reinvention, Aquarius found considerable recent fame as a disco star. When one starts at the top, it would seem that careers, like water, run downhill (although he may not yet be ready for the Chinese Constellation Fenmu, the tomb composed of the upper-left set of his stars). Its importance to several cultures throughout history is of little surprise, as this collection of stars, like the other 11 members of the Zodiac, lies along the ecliptic, the perceived path of the Sun over the course of the year.

This is a reprint of two articles I wrote for the Syracuse Astronomical Society newsletter, the Astronomical Chronicle, for April and May of this year. The series of articles is designed to introduce members and visitors to our equipment (the equipment generally found at Darling Hill) to help them decide what piece of equipment might work best for them. And so…
“What should I get?”
This is the first article in a series that hopes to provide useful answers to a commonly asked question at Darling Hill Observatory. The plan is to introduce prospective purchasers to the broad range of equipment used by the SAS regulars, including pluses and minuses, benefits and hazards, complaints and complements. For some of us, we’ve had the same core equipment for years and know their subtleties backwards and forwards. For a few others, they always have a new purchase to show and a new tale to tell (I await the show-and-tell from this past weekend’s NEAF purchases). Hopefully, having the first-hand accounts of a variety of equipment will inform you a bit more about future purchases than the flowery descriptions found on manufacturer websites.
