Another image from the ED72 on the star adventurer. 10x 3min guided. One thing that urks me is that with the QHY8L i need 30mm additional spacing for the flattener BUT this means that i don't have enough in focus to get perfect focus. Without the spacer, I dont have enough out focus. Either i need to suffer from incorrect spacing or small focus error. :/ Whyd they make the draw tube so short?!Did they really save THAT much by making the draw tube 5cm long?!
