I'm going to buy the
GSO RCA-300 Ritchey-Chrétien and put it on the new
EQ8 with either my ED80 or ED120 on top as a guidescope. This will also enable me to keep the wide-field capability when I reverse the roles of the scopes.
I've checked with Bintel the weight load of either combination on the mount and even with cameras, they both come in under limits so that's all fine.
My question is:
Is the 120 or the 80 best for guiding on this big scope and mount? Why? I'd like to hear your thoughts.
