Focus Masks

 
 

Here at High Point Scientific, we offer focus masks from Apertura, Astrozap, and William Optics. The Apertura Bright focus masks are designed using a large sample of data from a wide range of telescopes, so they are optimized for their compatible telescope size. This sets them apart from other Bahtinov masks on the market that use the same pattern, sized down or up, to fit the telescope outside diameter. For more information on how Apertura created the Bright Focus Masks, check out the comprehensive “Building a Better Focus Mask" article.

If you have a larger aperture telescope, such as a 14” or 16” telescope, the Astrozap full aperture aluminum Bahtinov masks are an excellent option. Astrozap values an astrophotographer’s time and understands the need for optimal performance and sharp focus. Their Bahtinov masks simplify the process. These Bahtinov masks are made in the United State from solid sheet aluminum to maximize durability and quality.

William Optics takes their Bahtinov masks one step further by including their innovative Bahtinov mask design with the purchase of their WYO telescopes! This means you have the ability to get super sharp focus out of the box! Unique to William Optics, their focus masks are made from acrylic instead of metal and provide 92% light transmission, making focusing easier.

Bahtinov mask designs are versatile, and we aim to help you find the right size, pattern, and material of focus mask to best fit your focusing needs!
