Mirror Clip Imaging Masks
Acrylic imaging masks.
Custom cut to your mirror needs.

Mask on customer 8" mirror.

$30.00 plus shipping.

Masking the clips on your primary will improve star images by eliminating flare. Note the three images showing stars The first image is after applying our mask. The bottom two show images from the same telescope prior to installing the mask. The buyer remarked "It worked fantastic. The stars have no more flaring whatsoever. I'm very happy with it."

Laser cut for precision, the mask is light weight 1/8" thick acrylic with one side flat black. Use small Velcro dots to adhere to the top of your mirror clips.

We need your mirror diameter, the ID and OD (width) of the clips, and how far inward the clip overhangs your mirror. Please measure using a millimeter ruler. With these dimensions, our mask will be easy to center perfectly, with the outside edge of the mask aligning with the outside edge of the mirror clips.

Pricing is for up to 12" mirrors. Please inquire for larger sizes.

Order - $30 each.
