SCT Issues - Guide Scope VS OAG and Filters for Plate Solving

Trying to improve imaging session reliability with the SCT at its native focal length (2315 mm): (1) Replace the filter drawer with a filter wheel and use the ZWO UV/IR filter for plate solving and focusing, (2) Evaluating filter offsets, (3) Re-focus the OAG guide camera using Stellarium features and a Bahtinov mask, and (4) compare guiding with an OAG to guiding with an 200-mm guide scope. Using a Digital Angle Gauge for OAG and Imaging Camera Setup:    • Using a Digital Angle Gauge for Off-Axis G...   Evaluating Back Focus for the Celestron non-Edge Focal Reducer/Corrector:    • Celestron SCT Back Focus Study at Native a...
