UPDATE - I've got another scope....
My double stack of William Optics refractors..
Zenithstar 70ED Doublet APO
Megrez 90 Fluorite Doublet APO
These scopes will play double duty, I will guide through one whilst imaging through another... This gives me the option of 621mm F/6.9 or 434mm F/6.2 or by adding the WO flattener, 496mm F/5.52 and 347mm F/4.96...
Should be a nice holiday from super long focal length imaging...
