Do you think its guiding? Mmmmmm! What do I do to correct that? I actually think its got something to do with internal temperatures in the scope. Before I start, I put a fan on to cool it down & the stars seem nice & round, however, it cannot be focussed well until you turn off the fan. Then after a while it tends to produce these stars. I wanna get an EQ6 Pro which is better than the 55 mount for the weight of the scope and see what happens. It also seems to get worse the more the scope gets vertical to the ground, but like I said, small mount big scope. Dunno, but I'll keep saving.
