My image of the Crescent Nebula is at
http://home.att.net/~dpersyk/new.htm
MX 716 camera on NP101, 4-inch refractor at f/5.4. 61 x 90 second unguided image stack.
I have processed and processed but just can’t seem to bring out the nebulosity in this subject. I assume the 1/3 moon present during the acquisition is responsible for the weak looking nebulosity. Usually 1 1/2 hour’s worth of acquisition yields a better image for me than this one. Perhaps also the Crescent is a tougher target than most.
Clear skies,
