| Comment : | This was the second test with relative auto guiding. It fail, it corrected the speed in wrong direction. It had something to do with the position of the telescope relative the pier, with or without a flip. The Masterflat doesn't correspond to all dust speckles I have on this photo and give an ugly look. Maybe the tail 10 o'clock, very weak. This is a kind of record for me, never seen that weak object before. |
