Hi again thank you so much for your help. I've been doing a lot of reading since, trying to get my head around how this actually works and specifically with my telescope. I Will definitely have a go with prime focus before trying projection. As I understand some people use a Barlow or powermate to both counteract the back focus problem and to have a "medium" magnification. Any thoughts on that? And again thank you for your kind and thorough replies
Here's a question from a happy astro-amateur from Denmark. I currently own a Sky-Watcher Explorer 130/900 and I think about making a setup with that and my Olympus OMD E-M10 MKII for some astrophotography. The camera has a micro 4/3 lens mount. I have been using my scope for a couple of years though I'm very experienced but I am a complete novice when it comes to AP. I've read good reviews of the Baader Hyperion eyepieces and think that a 21mm would be nice and it has M43 and T2 photo threads. So my questions are these: 1. How do I fit the camera on the eyepiece (adapter or not)?
