Horsehead & Flame Nebula (Orion) (click for larger Image)
Combination of 29x4 minute exposures (116 minutes total exposure). Takahashi TOA 130 (a 5" APO refractor) and Canon EOS D20a. My current image processing workflow is here.
Feb 10, 2006: I'm pleased to report that the image above was the runner-up out of 15 images in the digital_astro Yahoo Group's competition for the 2006 January Challenge! (You may have to be a member of the group to access the last link)
My current image processing workflow is here. The images from this session feature 29 light frames median combined, along with 9 dark frames. On the darks, I did both a median combine and an average combine, and then averaged those together. Temperature ranged from ~51 degrees F at the start of imaging to 42 degrees when I was packing up and doing my last darks. The rest of the images from this night...
