I'm not too sure if I'll need the extra back focus, I'm using a dslr now but will be moving to a ccd soon, so not sure what's the best combo for a ccd, oag, coma corrector, filter wheel.
but all that's still for next year once I get this up and running.
I want the mount and tracking to be stable and consistent first and get the OTA built as well. still heaps to do.
