Description

Early learning with the RASA 8in. Target is a bit small for the 400mm focal length, but turned out ok. There is some play in the camera mounting ring. I believe the camera was not centers well and focus was off on the right side. I have now made a shim that will keep the camera in the center where it belongs. I don't think I had installed the Celestron Focus motor yet either. I currently run auto-focus every 30 minutes for the 1st couple of hours then change to once an hour. I could probably use the temp change function to trigger auto focus. The RASA do seem to be sensitive to temperature change, so it's good to keep a close watch on the focus. Still learning
