Nice work!
Backyard EOS is a program that can connect to, and control, your DSLR for astro imaging. One of the really cool features is that it has a digital reticle for drift alignment. It uses the Live View mode of your camera and lets you rotate a digital reticle to do drift alignment like with an illuminated reticle, without having to swap between the camera and eyepiece

The down side is that you need a computer near your scope... but you'll probably need one for autoguiding anyway once you start long exposures. Good luck!
PS - the poor man's way for drift aligning using a DSLR is to use Live View on the back of the camera, slew the scope in RA, and use a Post-It note to mark the RA axis on screen. You can then drift align as if you were using an illuminated reticle
