ASTRO: Horse Head
I took this image a couple of weeks ago but I haven't been happy with the
way it came out. The images were noisier that usual. It has been really hard to process with out bringing out the greenish cast with the noise. It was imaged through a 4" f/8 refractor. Its 20 minutes worth of data with the 400D @ 800asa. Joe

Joe Wait for a below zero night and I bet it will be a lot cleaner. Or pile on a lot more frames. Still that's good for a DSLR. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh".

It takes a lot of signal to get this area right... I am kind of stunned that
you have that much in only 20 min. -- Regards, Doug W. www.photonsfate.com "J McBride" wrote in message ... I took this image a couple of weeks ago but I haven't been happy with the way it came out.
