I just recently got an adaptor so I can connect my DSLR lenses to my 183C. There are a few places in EKOS that require specific information about the telescope. My lens is now my telescope. And because some of my lenses are zoom they could be 70mm to 300m. How do I calculate the field of view, aperture, focal length...
Without this plate solving and framing is guess work.
Enter the set focal length in the EKOS Mount tab, you can also create a few presets. Once you click Save Telescope Info it should update the calculated focal length in the Align Tab.
