I've started doing imaging with a WO zs refractor on am updated Vixen GP mount and ASI294mc pro color. I also have a C8 which is fastar compatible from 1996. Contemplating getting a Hyperstar 8 for my C8 or V6 and purchasing a C6 OTA.
The price difference between the C6 /hyperstar 6 combo vs just the hyperstar 8 lens is small. I like the idea that the C6/Hyperstar is more portable and I might be able to use my Vixen mount and travel with the setup to our cottage. I do have an original Atlas EQ-G to take the C8 but not nearly as portable - my family takes up too much room in the car.
What do I lose going with the Hyperstar 6 vs 8? Wider fields with the 6? Better fine detail with the 8? The main use would be EAA / fast imaging / sharing the experience with friends/family where speed would help.
