Description

M104 has always been one of my favorite objects to view through an eyepiece. I've not

imaged this object with my Orion ED80 Refractor so when I finished taking my light frames of

M63 last night I also took 50 light frames of M104. I had tracking problems last night and not

even one of my light frames of M104 were what I would consider usable. Normally I would just

say Oh well maybe on another night and trash the images. However it kind of ticked me off and

I decided that I was going to get an image regardless. Most of my processing time was spent

trying to repair the star field background. Luckily Gimp has an Astronomy plugin called star

rounding that helped and I also used blurring and some other tools. By no stretch of the imagination can this be called a good image. However it is my most recent attempt at imaging

M104 and I figure why not show the bad with the good. When I can figure out how to fix the

tracking problem I'll image M104 again and hopefully show improvement.
