Stacked 6 240 sec images in MaximDL on the stars. Stacked the same images aligned on the comet, Combined the 2 images in Photoshop and used Topaz Denoise to clean it up a bit before final stretch touches in Photshop.

Woke up this morning at around 4:30am PST in Valencia, CA. I logged into my remote observatory in the Lockwood Valley, CA and captured a set of 240 sec, 140 sec, and 60 sec images using my Radian 61 f/4.5 Imaging APO Telescope with an SBIG 8300c camera. Was very surprised to see how close these objects were (using your website as a guide). This is the first quick process using only the 240 sec images but will see if combining all of the images will give a bit more detail once I get a chance.
