Bahtinov masks are the perfect accessory for precise focusing in astrophotography. You can easily and reliably verify when you have reached the correct focus point: no more mistakes!
How to mount the mask on the telescope:

Each mask comes with 2 plastic screws used to securely rest it on your telescope. Simply mount the screws into the 2 holes and then place it on the dew shield of your telescope. This system is universal and allows this Bahtinov mask to be mounted on various tubes within the specified diameter range.
This focusing method is much more effective than the Hartmann mask: in fact, light disperses around the 6 holes, whereas the Bahtinov mask, by working on diffraction, avoids dispersion and allows for much more precise focusing. Also for high resolution.
