Maximum Full-Frame & APS-C Focal Length filter

[scottstirling]

1. Set a focal length
2. Choose full frame or aps-c (maybe more if necessary) sensor
3. Annotate and/or list objects in the astrometric field of view whose angular dimensions fit within the selected sensor at the given focal length

Sounds dumb if the image is already a a solitary object filling the field of view but not as dumb if the image is a wide field and the user wants to see lit up which objects would fit a different focal length and/or sensor combo.
