Hi,
I'm getting a SkyWatcher 6" F5 (parabolic) reflector and I may require a coma corrector for my astrophotography and visual use depend on how good is the scope.
Anyone here had ever use one before? Can give any comments and recommendation?
Thanks and have a nice day.

Coma correctors are pretty expensive toys. On the average about US$250-300 each. In my opinon, I don't think you'll need it *unless* you are really a hardcore imaging person i.e everytime you set up a scope, it's your camera lens that's looking through the scope rather than your eye 
For visual, most people would just bear with it. Just like achromat refractors and their chromatic aberration, for example. A lot of people own them, but how many actually do buy MV or VR filters for them ?
