Hey everyone
, i have had two imaging nights so far with my ASI1600mm, the first night i had some focuser tilt issues so i fixed that by tightening things up and then last night when i went shooting i noticed i had these strang ghost stars in my images. any idea what it might be and what steps i should take to try eliminate the issue?
im using a saxon ed 100, 0.85x ed 100 focal reducer and flatterer, ASI1600mm with filter wheel and the zwo off axis guider with a QHY5L 11. thanks guys
