I took 25 each 30 second images of Comet Garradd last night. Combined them into the following video.

Bubble Nebula
I was able to get some really great guiding working last night! I have taken images of the Bubble nebula last year with the DSI IIc. so figured I would give it a shot with the modified DSLR. Here's the results:
SW 254N, EQ5 pro, guided, Canon XT (modified) 3 minute images, ISO 1600, 33 minutes total.
From Wikipedia:
NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region[2] emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7[2] magnitude young central star, the 15 ± 5 M☉[4] SAO 20575 (BD+60 2522).[7] The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.[7] It was discovered in 1787 by Friedrich Wilhelm Herschel.[6] The star SAO 20575 or BD+602522 is thought to have a mass of 10-40 Solar masses.
