It has probably been asked before, but here goes anyway.
I'm looking at getting an 8" imaging scope and I keep coming back to these two options.
The Astrotech or GSO 8" RC
The Vixen VC200L

I know about the spider vane problem on the VC and the long image train on the RC.
How much of a difference does the F8 1625 vs the F9 1800 make?

So much to read about both but can't seem to find any good comparisons between the two!

Cheers
Shaun
