Second upgrade for the week that required the earlier upgrade to go ahead 🙂
This time the in-storage Sky 90 and filter-wheel have gone back on. It was taken off over a year ago as I got terrible star shapes with the M26C camera and I put this down to collimation being way out. Realised later that it was the camera flatness that was way out, but I left the (flattened) camera on the TS80 and worked with that. Checked the Sky 90 collimation while it was off the array and it looked alright to me. So now need to see if it is indeed alright next imaging session. Problem is, the computer that drives this imager decided at this very instant to pop its clogs – there’s always something!!!
