I remember reading something like this before. I have been learning EKOS and tried Astrometry and it worked great. I only tested it once.
Last night I tried again, and again it worked great. But only that very first run of the evening. Two minutes later I tried again, at the same spot in the sky and it never found a solution. I tried several times during the evening with no luck. Then I powered off my equipment, fired it all back up, and again Astrometry found a solution quickly. But it only worked that first time. Repeated attempts timed out. Before I jump into detailed error tracking, I was wondering if there was an easy fix for these symptoms?
