Eyepiece Calculator

Recommended Posts

Following on from some testing and comments here in SGL I have attached the final version of the Simple Eyepiece Calculator. It's a very simple to use tool which should save you from carrying out all the calculations and hopefully provide some guidance. All you have to do is input the data into the clear cells. The file is tiny, does not contain any macro's and is protected but without a password - so feel free to change it! Either the FR (Focal Ratio) or FL (Focal Length) can be input into the first cell, similarly the FOV (Field of View) cell will accept either AFOV or TFOV. Please be aware that the guidelines are just that - guidelines :D
