Mirror Clip Imaging Masks

$30.00 plus shipping.

Masking the clips on your primary will improve star images by eliminating flare. The images at left show a primary mirror without and with our mask. The star images below show results without and with the mask.

Our first two buyers remarked "It worked fantastic. The stars have no more flaring whatsoever. I'm very happy with it." The second buyer sent the four comparison photos, writing "Love the aperture ring! Here's a great results example of the imaging ring I purchased."

Precision cut from light weight 1/8" thick acrylic, one side flat black. Adhere with small Velcro dots or similar.

Provide your mirror diameter, mirror clip overall inside to ourside width, and amount of clip that overhangs the mirror. Please measure using a millimeter ruler, and example is shown at bottom left.

Your mask will be easy to center perfectly; the outside edge of the mask aligns precisely with the outside edge of the mirror clips.

Prices are for up to 12" mirrors. Inquire for larger sizes.
