Hi. I have added my equipment to my profile, but the FOV I am presented is vastly different to what I see through the lens. I have added some pictures of my equipment profile. Have I done something wrong or is it a bug? Thanks

(Focal Length / f number)

The framing also depends on the Simulator setting panels, with options like cropping, barlow and reducers. If you are sure everything is correct, maybe some screenshots of the Telescope Simulator settings could help figure out what could be going on.
