Shipping Calculator
A Bahtinov Mask is a plastic plate with laser-cut slits that is attached to the telescope's front end that is used to help attain the most precised focus through your telescope. Bahtinov Masks are extremely helpful for astrophotographers using an astrograph imaging telescope without an eyepiece, and can be used by astrophotographers of any level who just want to get a clearer best shot!
How To Use
Centre desired object is centered in the eyepiece. Attach the Bahtinov Mask using the adjustable padded pegs until secure onto the telescope, and focus the telescope until the diffraction spikes are symmetrical. The final result should appear like the image 'Center' spike.
