Another surprise clear opportunity gave me a chance at The California Nebula with the 300mm. Though the transparency was very variable with thin cloud drifting through I managed to obtain 10 mediocre subs before it clouded over completely . Of interest on the final stack was an obvious trailed star which I have indicated. I include crops from the first and last subs which show the movement over approximately 100 minutes. I have now managed to identify it as Minor Planet 15 Eunomia....an unexpected bonus! Details: Tair-3S 300mm@F5.6 . 10x 8 minutes @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
