Image Description:

This is a widefield shot of the γ Cygni (aka, Sadr) region in the constellation of Cygnus. I blew the focus on this, but the shot isn't too bad nonetheless. Of course, it's hard to tell that the focus is blown at the image scale displayed herein. <grin> A higher resolution image of this widefield shot is also available, as is a closeup of the immediate Sadr Region from last year. North is right.

This is my first webcam shot of the moon, using the Orion ED80 rig I used to image saturn the same night. More of an experiment than anything else. I used the Lunar and Planetary Institute's Consolidated Lunar Atlas and the Virtual Moon Atlas to figure out what portion of the moon I had captured. North is up.

Image Description:

This is "Second Light" for my new, modified, Canon EOS Digital Rebel XT (350D). (First Light is available as well.) I was only able to get 8 exposures in before the marine layer (fog) wiped me out, but the modified camera captured a decent amount of Hα from these relatively bright targets in that relatively short window. This is a well-traveled field in Sagittarius containing several of the showcase Messier objects of summer: M16 (the Eagle Nebula), M17 (the Omega Nebula), and M24 (Sagittarius Star cloud), plus some other goodies. This is the full frame, shrunk for display on the web. A full resolution image is also available. North is right.
