About this product
Custom made secondary mirror masks to fit the CarbonStar 150 and CarbonStar 200. Users experiencing halos and non-symetrical flares around bright stars have found that putting a mask around the secondary eliminates almost all of the these, so these masks were made to slip over the secondary and block the outer 2 mm of the secondary mirror, cleaning up images. You can secure these to the mirror either with a few pieces of masking tape as a shim until the tension feels right and it won't fall off, or just a small drop of hot glue or silicone out of the light path. These are VERY lightweight; 5-6 grams. Printed out of PETG-CF so they're strong and heat resistant as well. Painted flat black on the main face to further minimize any potential scatter.
