A test with Skywatcher 200/1000mm Explorer. A long time it was standing around. Now I decided to test the photo capability of it. It is modified with an (crappy) focuser and the inside is lined with suede.
I think that the focuser is nit lined up with the optical axis. If someone can help me with collimating newtons, you are welcome!
