At What FL is OAG Required
Is there some conventional wisdom concerning at what fl should you move from a guidescope to OAG? I've been doing ok with my 60mm ZWO guidescope/Metaguide setup on my 1000mm fl Mak-Newt and the 1250mm 10" imaging newt. With the RC08 at 1625mm fl will I still be able to guide effectively? Mount is a NEQ6 Pro, guide camera is a ZWO130mm (with a pixel size of 5.2), imaging camera is Canon 450D DSLR (with a pixel size of 5.19).
I should add that the RC08 is the lightest of the scopes mentioned above, and has two full length dovetails stiffening it.
