Don't forget Ken your image looks like you are not using a barlow. When you increase image scale you need higher gain or else the image will be under exposed. Higher gain means more grain and processing artifacts.
Matt, collimation is your next issue to deal with. You have a good start and with some good seeing and a thoroughly cooled scope you will make big steps each time. That said I have waited 2 years to get the Saturn image I recently posted. It is very dim and the larger I go the more frames I need. Which means I need lots of good seeing.
Congrats on joining the frustration club. Hope to see more images from you.
