Hi Jacob, I'll throw my 2 cents in. I bought a GSO RC6 to use as a grab and go (a half decent 5" or 6" astro capable refractor would cost a lot more)

The only thing I don't like about it is the F9 part, it's seriously slow. But as far as collimation goes I have only ever had to tweak the secondary, and the field is flat (on my crop sensor 1100d anyway), which is why I got it in the first place, no reducers or correctors needed.

I think most people get into strife when they start messing with the primary collimation, I was told to leave that alone and just micro adjust the secondary.

Your HEQ5 pro will handle the RC6 or 8 , but if you want quick results photography wise the lower the f ratio the better. For the same $ I would be looking at a 8" F4 reflector, you will need a coma corrector and some collimation skills/patience but once set up you will get some nice images quick and easy.
