Mirror clip mask
Eliminates flaring


Mirror clip mask
$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." Another 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.

Required dimensions when ordering:

1. Mirror diameter
2. Mirror clip width from inside to outside.
3. Distance mirror clip overhangs the mirror.

Please measure with a millimeter ruler, an example is shown below.

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

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


Example:
Clip width 17 mm, overhang 8 mm.


Please use the clip width and overhang example at left.

Order - $30 each.

Clips: Width and Overhang
Shipping: $6 to U.S. Destinations. Inquire for non-U.S.

A PayPal shipping invoice will be sent after order receipt.
