Hi Richard. I had originally planned on getting one of the gso 8" newts either f4 or f5. The only reason I was looking further was because I want to use an OAG instead of a guide scope and the newts probably won't come to focus. I was aware of the need for coma corrector or field flattener. Thanks for your help.
Thanks everyone for your help, you have definately given me some things to consider and think about.
