Hi, I have purchased a zwo 585 mc air to put onto my Askar 80 phq telescope with no reducer or flattener. I have added spacers totalling 37 mm or there abouts but still I cannot get focus. I have tried on the Sun and can get the Sun on my screen but no detail. I have a white light filter on the front of the scope and keep moving the draw tube in and out. The image I get is just a white blob with a bit of blue fringing. I have tried with and without a filter. Any ideas please.
