I have discovered that dark frames make all the difference: images are clearer without all of the noise. I have tested the dark frame function on the Meade DSI CCD camera and it works well. Set it to create dark frames (it takes about five minutes), put the lense cap on the telescope, and go have a coffee. After it prompts you that it has completed, remove your lensecap and continue to take pics. The images are far clearer and the background is dark. I have dozens of pics that were enhanced by dark frames: I will post them soon after I edit them with my new install of Photoshop.
