Extend telescope and camera lens selection
The primary and guide scopes can now be selected in the equipment profile. However, we seem to be missing a couple of features:
- Ability to add a reducer to the combination, so that the final focal length is sent to INDI.
- Ability to use camera lenses, which are popular with KStars. Camera lens have different FOV computation than telescope in order to calculate the field of view, and therefore there should be a separate entry for them.
