Farpoint dSLR Astrophotography Focusing Tool - Bahtinov Focusing Mask 77mm FP443

Farpoint 67mm Camera Filter Bahtinov Focus Mask is an ingenious new way to easily focus your DSLR camera, webcam or CCD camera for astrophotography.  Pavel Bahtinov, a Russian amateur telescope maker and astronomer, created this simple, very intuitive method and the device has universally been named after him: The Bahtinov Mask.

This Bahtinov Focus Mask snaps-in to your camera lenses that have 77mm filter threads.

The Bahtinov focus technique works best with longer focal lengths and becomes less useful with shorter focal lengths. The practical useful limit is around 100mm focal length or longer.
(Don’t confuse focal length and camera lens size).

Farpoint manufactures this “lifesaving” astrophotography tool out of virtually indestructible ABS plastic. In addition to Bahtinov masks for DSLR, webcam or CCD camera lenses, Farpoint also makes Bahtinov masks for telescopes.


How to use it:
This dSLR camera lens version of the Farpoint Bahtinov mask would simply snap into place in front of the lens. It might be beneficial to snap it into a filter that would screw into the front of the camera as it makes it easier to remove it once you focused it, but the use of an additional filter is not a must have. Otherwise a filter is not included, but can be purchased separately.

Also, see the Youtube videos below.

Each mask comes with a leaflet that explains how to focus the telescope with the help of this Bahtinov mask.
