Hello all. I am working on a decision for a guiding solution for my C9.25 SCT. I intend to buy the ASI294MC Pro camera. I now need your advice helping me to decide between a guide scope or OAG.
The Celestron OAG has a mix of good and bad reviews as expected; however, I was leaning in this direction since it is complimentary to my Celestron SCT and has a large prism. My primary concern is flexibility. Based on seeing conditions and target selection, there will be times when a corrector is, or is not, warranted. While the OAG may reduce errors from differential flexure and mirror flop, I seem to lose flexibility as it appears that using a corrector/reducer or barlow does not work with an OAG.
With respect to a guide scope, I was looking at the Stellarvue F50 50mm Guidescope W/Straight-Through Helical Focuser. I am wondering if the 210mm FL of this guidescope is sufficient for a 2350mm FL SCT (or 1480mm if using the C/R).
Any feedback or thoughts would be appreciated.
