Bahtinov Mask for 100mm Optics
Overview:
The Bahtinov mask is used to focus small telescopes accurately. Although masks have long been used as focusing aids, the distinctive pattern was invented by Russian amateur astrophotographer Pavel Bahtinov.
Simply place the mask in front of the main optic of your telescope and take a picture. Look at the diffraction spike pattern and continue until the spikes are even. Using a Bahtinov mask is the easiest way to get into focus.
Notes:
- This 100mm mask is great for 90-105mm class telescopes
