All users:
 These are the 64 bit version. If you need the 32 bit
it is also available, but most computers these days are 64 bit.

The first time you run it it will give an error. That is because it looks for a file user.txt with your pupil
and telescope information.  Even if you don't give it any, it will write a user.txt file on that first run and
the error will not be seen again.

If you have eyepieces that are not in the database, please send me their names, power and FOV and I will add them.
I will then send you a new copy with those included.  (I will wait to add any others I get, so it might be a few
days or week or so.

I have a program that I wrote that provides information about which eyepieces will work well with your eyes.
It calculates based on your pupil size how much light is lost from a given telescope/eyepiece combination.
Currently its database holds ~300 eyepieces of various brands, and I am willing to add others if I can get the information.

Measure your exit pupil
One simple way to measure your pupil size in the dark is to stand in front of a mirror with a mm ruler held next to your eye
in a dark room and snap a flash picture with your phone. According to what I have heard (haven't tried it) you can measure
your pupil size as it doesn't change fast with the flash.

Fast scopes in particular can limit which eyepieces work as you get older. They effectively make the aperture smaller
as the light cone is too big for your pupil size. This can help you see which size eyepieces will work best for you.
