Bahtinov mask for 4” refractor
I printed an extra bahtinov mask for my skyrover115
with an outside diameter of 141mm. This is a simple clip type. Not beautiful, but very functional.
I’m sure it can be adjusted to suit 130-141mm telescope.
Available (free!!) for pickup in Brighton if anyone wants it.
