so I want to create custom eyepieces for software (like skytools / sky safari, etc)...so when I plan my sessions I can see what FOV I will see.
everything is afocal for now
so I want it to look like this:
NV - 67mm
NV - 40mm
etc
is it as simple as making a custom eyepiece then focal length then 40 degrees? just wondering if anyone has done this or organized it well in their software.
