I just got an AP900 GTOCP2 from a friend. I used this mount 10 years ago and have forgotten a few of the basics. I was looking to track Comet Neowise and completely forgot how to figure out what Custom RA and Dec information to enter into the AP V2 ASCOM Driver window. I did visit the JPL Horizons website and downloaded the data but was not sure which data to use.
Hope someone will help me figure it out. I did once, for the life of me cannot remember what I did.
