Hi Mark, you've done a good job with the 10" and WO finder there, I presume you can use the WO for either guiding or semiwidefield unguided stuff via the flip mirror if you wished. Selling the obs so you can get bigger one to fit the 20" Hmmmm?
My major problme in trying do the same sort of thing was the excessive rear weight of the SCT and WO triplet scopes, there was no way I could get the SBS to balance when the EQ6 was horizontal. It just wanted to rotate vertical depending on which scope was weighted the heavier. That's when I kludged the top counterweight over the axis. Fixed the balance problem but introduced vibration and flexure aspects and needed another weight on the bottom! Time for a total rethink, he said.
Dump the big guidescope, put the finderguider on the RHS, and add scopes as needed to the LHS. Ahhh, that's better.
Next stop is the threatened Hyperstar install, which, with the alternative 6.3FR option, will hopefully give me a good range of FL's from the SCT. It may turn out that the 8" 1000mm Newt + MPCC is overkill, we'll see. It's all good fun.
