Hadley Telescope Moon Mask/Filter

This is designed to filter out some of the light when viewing the moon. On clear nights with a full moon, it can get pretty bright coming through the eyepiece.

I took inspiration from this model here: https://www.printables.com/model/251526-hadley-primary-mirror-cover-remix

Made the hole larger, and added a different handle borrowing from another remix: https://www.printables.com/model/251526-hadley-primary-mirror-cover-remix
