Hi Rob. I'm a bit of an aperture mask nut as well On my reflector I use the standard 3 holed (round holes) mask. Depending on what I'm looking at I will leave the 3 holes open, or I will close 1 up....or 2 for that matter, It's a variable brightness mask lol.

I have one as you describe for the refractor as well..never thought of making one like that for the reflector..
