Homemade Focus Mask for VRC-6

[hemmi]

Today I decided to make a bahtinov mask for my new VRC6.  The mask just slides inside the tube and rest on the secondary.  The mask pops in snug to the scope cover for storage (as seen in the pics).  I cut this out of 3/16" abs black plastic on a CNC router.

Here is a quick diffraction image of polaris to test.  I think it would work better on a brighter star.  But regardless, it seems to work fine.

I built the CNC router myself.  See my homemade DOB thread, as it was made with the CNC.   I actually made the CNC to support all my hobbies.  I have many..lol
