Capricornus

Object: Capricornus
Location: Savoy, MA
Observer: Roland Roberts
Time: 8 Aug 2002
Camera: Pentax K1000, 50 mm f/1.4 lens
Film: Kodak Elite Chrome II, ISO 200

Capricornus lies low in the southern sky as seen from the mid-northern latitudes. It is most easily visible in late-summer (depending on how late you like to stay up, you can see it in early summer). Like most areas away from the Milky Way, Capricornus looks relatively bare. Only one Messier object lies in Capricornus.Capricornus looks to me more like a big "V" or even an open mouth than a sea-goat, but I don't get to name constellations… At the time this photograph was taken, two planets and several asteroids were visible in the constellation of Capricornus, although only one of the asteroids was bright enough to show up unambiguously in this photo and even then, only when viewing it at the 800-pixel wide size or larger. Uranus is/was a (marginally) naked eye object, provided you know where to look. Neptune requires at least binoculars. Neither are very impressive. However, they can be distinguished from stars using a telescope, something which is true of all the planets except Pluto. Labeled in the picture are the following objects:

With the exception of M30, all the Messier and NGC object are actually part of Aquarius.

Film photography is, in one sense, the easiest of the possible ways to get pictures of the night sky. In fact, with nothing more than a camera and a tripod, you can start taking pictures and pick out the brighter stars with exposures of as much as 20–30 seconds, depending on what part of the sky you are pointed at. If you don’t mind star trails, you can expose for much longer. And, if are at least a little mechanically inclined, you can build a barn-door tracker which will let you take exposures of up to 10 minutes (or even an hour with a more sophisticated design. A barn-door tracker is not what we used here. I have only a modest set of mechanical skills and we live in an apartment which is large only by New York City standards. With two small children running about, power-tools and construction messes, even transient ones, are not a good idea. So I bought a CG5/EQ4 mount with drives and and a small “table top” to fit on the dovetail bracket where I can mount a camera. This is the expensive way to get started and the mount is overkill for the load I put on it, but I hope to eventually put something like the Celestron C5 Schmidt-Cassegrain on the mount. My set of portraits will slowly grow, and I hope to eventually have a collection as nice as what are on Jeff DeTray’s web site, but for now this is what I have.
