Hi, Here is a blend of 4 frames (approx 12 minutes)shot in JPEG mode of my modded Canon XTi shot through an Olympus 100mm Zuiko (film) lens. Someday I'll settle down and shoot raws and flats and darks but for now I'm having fun just blasting away.

Hi, Here is 32 minutes (16 frames) with my Canon XTi and an Olympus 50mm lens. The colors are hard to bring out because of extinction from my 43N latitude. This as another image shot in JPEG mode.

Hi, This is my first post to the DSLR forum. I usually post to the CCD forum....anyway I had some fair skies Wed. night so I nabbed the Trifid with my C11 working at f/5. I used a modded Canon XTi set at 800asa for approx 20 minutes total time in JPEG mode.

Hi, from the same night as M20. Some of these frames were shot at 400asa. This is about 25 minutes total time. You can barely make out 15.5 mag galaxy ic4617 in the upper right.

Hi, This is the first object I imaged from Wed night. This is 40 minutes total @ 400asa with a modded Canon XTi through a C11 @ f/5. I tried a shot at f/6 but it was too much f.l. for this object with the 1.6 crop factor. The stars are ok at f/5 but I want to try this object at f/4 just to see what I will get.

Hi, This is 20 minutes of data shot at both 800asa and 400asa. The 400asa was used to add color saturation. I used a 100mm Zuiko lens @ f/2.8 on a modded Canon XTi. I had to increase the compression to fit under the 500k limit.

Hi again. This is my last for the night...I promise. I needed a bunch more time at a longer f.l. but this is one of my favorite PN so I took a pot shot at it Wed night. Its only 12 minutes worth but I got a little somethin. Modded Canon XTi through a C11 @ f/5. I might try f/6 or even f/11 next time. I noticed during processing that the focus is a tad soft...probably becuase it cooled off during the night and shifted the focus. This was the last object I imaged.

Hi, It was pretty gusty last night so I was limited to wide field imaging. Here is 27 minutes of data taken with a Canon XTi and a 50mm Olympus zuiko lens@ 800asa. I should have stopped down 1 more stop to get rid of the elongated stars near the edges.
