First picture is with my 4" scope back in May, then I acquired a 10" and got a little more detail last week. I need to work on my collimation as I believe that is my main issue with the second picture, I've got a catseye on order so I'm hoping that will take care of it. Pictures were taken using a modified hp-4110 webcam. Any other advice?

Here's a good article on collimation. I've never used a cheshire, but instead just do a star test before imaging. It's important to re-check if you significantly change the position of the scope due to potential for mirror flop and flexure.
