It's semi-permanent - I leave my G11 tripod outside and only bring in the OTA, but that has alignment marks so I'm pretty sure it's remounted in the same position. I check PA with SharpCap or PHD2 DA, and it never really changes much. I currently re calibrate every night but plan to try only doing so if I point to a different location in the sky (as is often recommended for permanent installation). Either way, I would like to automate it all through SGP and it appears the only thing holding me back from accomplishing this is one overly conservative time-out period in SGP.
Thanks!
