Meade DS-114AT with Autostar 497. During alignment and some basic observations the stars may drift slightly over time, and sometimes wiggle with the motor motion, so I have settled for taking images of no more than 10 seconds exposure.
I was recently reminded of High Precision mode and have used it to find galaxies very easily. Then the scope seems to hold the galaxy centered very solidly. It looks like I will be able to take longer exposures. Tonight I got a few at 15 seconds that kept stars nicely round instead of letting them wiggle. Unfortunately the sky clouded over before I could test much.
So my question is: does High Performance mode somehow help with tracking as well as with finding? I also have used the Sync function - sometimes two or three times in a row - and that seemed to help, but not nearly as much as High Precision seems to have helped.
