Bahtinov Mask for Hadley

Bahtinov Mask for for the Hadley telescope. If you are unfamiliar with masks, they can help you focus the telescope more easily on stars. This is designed to fit over the web. 

Warning: This part is experimental. I have not been able to test it in the field as dark skies in my area are rare, but should work well if you skies are dark enough.
