Welcome to IIS Nathan. You'll need an equatorial mount for long exposure deep space imaging; Skywatcher HEQ5 or EQ6, Celestron Advanced VX or CGEM are commonly used. The EQ6 and CGEM are quite heavy but also more capable than the other two.
The Skywatcher Esprit Apo triplets are a good choice for DSO imaging. They come with a range of accessories including a flattener and adapter ready to fit your Canon straight onto.

I've recently started imaging and I've particularly sought out an easy to use setup, even if it's not the most capable. My gear:
Celestron Advanced VX mount
Skywatcher Esprit 80
Lacerta stand alone autoguider
The mount has an all star polar alignment routine which makes polar alignment easy and the guider corrects for imperfections in the mount drive gears.
The most common setup is probably an EQ6 mount with a guide camera both being controlled from a laptop.
