Mirror Mask Sky-Watcher 150

This is an improved version of a primary mirror mask for a Newtonian telescope.I've designed it to fit a Sky-Watcher 150PDS, but similar scopes should work as well.Make sure to measure the distances of the screws before printing for another telescope manufacturer.I've designed the mask in a way that there should be minimal reflection on the inner walls, see the fourth picture.Applied some flocking material afterwards.Additionally, this mask has a larger outer diameter to close the gap from telescope to mirror mask.Feel free to leave a comment after your first light!
