You can use the "Add" and "Delete" buttons above the Telescopes field 
and the Eyepieces field to add and remove items from these fields.  If 
you add items the heading items need to be adhered to, for example in 
adding telescopes, the first item needs to be the diameter of the 
objective lens in millimeters, the second item needs to the F number or 
speed of the objective lens like F8, and the third item needs to be the 
description of the scope (which can be any text).

You can then select a line from each field and it will calculate the 
power and field of view for that telescope and eyepiece combination.

The "Design" part is not finished, I'm still working on it.

I'll add some help to it when I get the time.
Being retired, I'm not tied to my desk like when I was working so my 
response to the email is only hit or miss.  :)

Sorry for the slow response.
Have fun,
Glenn
