Classical Bahtinov Mask
Classical Bahtinov Mask
The Skylabs Classical Bahtinov masks are designed to obtain a very accurate focus. This type of mask delivers a diffraction pattern, creating a set of three fine spike lines around a bright star. Once the three lines are aligned in a single spot, the focus is achieved.
Product Information
The Skylabs Classical Bahtinov mask is based on eco-friendly high-density cardboard (kraftboard). The material is not only durable but also delicate with the telescope optics, especially for MCT, MNT, and SCT. The thin material and the CNC precision cut shape ensure an extraordinary precise diffraction pattern.
If you want to achieve even better focus, consider using our Tri-Bahtinov masks, which generate a set of 18 spikes that help to increase the accuracy in that process.
How to Order
Each Skylabs Classical Bahtinov is created on-demand as it depends on each telescope's characteristics. To request one of these masks, you will need to provide the following accurate values in millimeters:
- Telescope brand and model.
- Focal Length.
- Secondary Holder Diameter: is the diameter of the secondary holder.
- Secondary Diameter: is the diameter of the secondary mirror.
- Aperture Diameter: is the diameter of the main mirror.
- Inner Tube Diameter: is the diameter of the inside wall of the telescope tube.
Size Compatibility
We recommend this type of mask for telescopes over 140mm of aperture. If you have a smaller telescope, consider using the Skylabs Enhanced Bahtinov masks, which has been designed for camera lenses and small telescopes, and it is several times brighter than traditional ones.
Currently, Skylabs can not provide classical Bahtinov or Tri-Bahtinov masks for telescopes with an outer diameter bigger than 300mm.
