Focus Focus FOCUS

Another fully automated night last night under clear clear skies (about 40% new moon).

Still have focus issues - or rather automation ones - the FocusMax routine is not reliably adjusting the focus and, if it fails, it reverts to the previous setting so the consequence is that as the temperature drops and the telescope contracts in size the focus shifts and the images get steadily

worse. The best of the images is on the left - nice and tight. The overall colour image, right, looks far too soft though... (RGB 30:30:30)
M16 is the same....(30 mins Ha)
