I have an 11 year old C14 @ F5 guided with a piggy backed 4” F7 Stellarview refractor mounted on?

an AP1200 and I get excellent up to 20 minute guided sub exposures. I use a SBIG Remote Guide

Head in the refractor and a SBIG ST8xme imager in the C14. I can image for hours losing a FEW

exposures due to mirror flop or differential flexure. When any flop or flexure occurs I usually lose

one sub exposure as the mount corrects quickly. I don’t get much flexure in the refractor because

of the carbon fiber tube. The C14 is covered with insulation. The mirror flop only occurs when crossing

the Meridian. I do not need to worry about finding guide stars and I can use any filter on the imager.

I’ve tried a couple of OAG’s and got tired of looking for guide stars long ago. With my present setup,

I can be guiding and imaging in minutes.

Clear skies,

Bob
