Chad,
Please forgive me for harping on this, but I again strongly recommend you get Nebulosity BEFORE you get a new camera. No camera will be any better than the capture software you use. Binning, as an example, is a critical tool. Let Stark Labs Nebulosity take you through how to use your existing camera and equipment, and get very proficient at that one piece of software and your existing equipment.
Once you do that, you may discover that there are nuances in images that you cannot capture, such as those revealed in narrow-band imaging. That is a whole new area but will not work well for you unless you really know how to use both your capture software and the camera basics. If you jump to a more sophisticated camera and its vendor-provided software you will need to learn to use something that only works for that vendor's equipment. If you get Nebulosity, you will be able to spend your time learning to use a capture and processing software package that will work for whatever equipment you get down the road.
I write this not because it is some great theory, but because I wasted a LOT of money on cameras, scopes, and other stuff when my limitations were software based. Get good with Nebulosity and your Canon. Among other things, I would recommend you do some wide fields along the Milky Way using your kit lens that came with the camera. Shoot a series of five or ten-minute exposures and do a survey of the Milky Way. That will give you a good set of references. There are plenty of panoramic, stitch-together apps out there that will allow you to combine the images if you do a 50% overlap in the exposures. If you go for ten minutes, you should see a LOT of nebulosity popping out. Figure out what you are seeing by name and then go after the rich areas with your telescope.
I, and the rest of us, have been down many a blind alley. Getting equipment before software is one of the most frequently made mistakes.
