Has anyone any experience or comments on these scopes. I am trying to avoid the complication of off axis or guidescope guiding. With my ED80 unguided on an neq6 mount i can get ~70% pictures with round stars at exposures of 3-4 minutes. My other scope is a c9.25 which even with a .67 focal reducer will still give me a focal length of around 1600mm , which is unlikely to give me long exposures without elongated stars. I was considering the advantage of using one of the 6 inch F4 GSO image optimized newtonians. Same focal length as the ed80 , about x3 light gathering power , better resolution and should track on the neq6 mount like the ED80. On the other hand coma may be more of a problem. Any thoughts?
