Hi all, I'm a first time poster and attempting to make my first steps in astrophotography. I have the exact same setup as quoted below: However, I'm completely unable to achieve focus. With my flattener set to 12.7mm as described above (to obtain 67.7mm), it's as if the camera is set too far back so that even with the scope focusser fully inserted (as far forward as possible), the image is completely blurred. As I retract the scope focusser, the image just gets more and more blurred. I've taken some pictures without the flattener, and with the flattener set to 0mm, and have no focusing issues, but of course I lose the benefit of the flattener in that case. The maximum I can set the flattener to and still focus the scope is around 5-6mm. I'm trying to determine if there's an issue with my kit or if I've overlooked something. Thanks for any help you can give! Alexander
