This customizable design generates custom Bahtinov masks, which are used to aid focusing telescopes during astrophotography. Havn’t done one for my 10″ though. I’m mqsk to give this another go with a more sturdily constructed mask.
We’re sure brentb would love a Tip, but unfortunately they have not setup their accounts to receive them yet. Using one of these masks attached to the front of your camera, accurate focus can be achieved using the built in screen of a DSLR camera or the captured image of an astro-CCD camera on a computer screen.
Most people seem to say the exact dimensions aren’t critical? Focal length must be a positive number.
The Bahtinov Mask invented by Pavel Bahtinov, a respected Russian astro-photographer, will work with both kinds of camera by producing a distinctive ‘diffraction pattern’ in a similar manner to the way a four vane secondary mirror spider vane on a Newtonian reflector produces a four pronged star and that of a three vaned spider vane produces a six pronged star.
Show Some Love – Tip brentb. Focal length mm Focal length must be a positive number. The Bahtinov mask is a device used to focus small astronomical telescopes accurately.
Thing Statistics Views. Scale to 72 DPI. Each page has 1 inch overlap and markings which indicate how to connect each piece. This astronomy-related article gennerator a stub. I’ve also read reports on printing the mask on paper with a laser printer and then transfering it to a glass using a hot iron – method which is suitable for making a small mask for DSLR or a refractor.

It consists of a disk made of opaque material fitted over the telescope bahtinob with slots cut out in a specific pattern devised by amateur astrophotographer Pavel Bahtinov. The angle from the horizontal of the angled slots.
Pavel Bahtinov has kindly released his designs into the public domain so anyone with a little bit of DIY experience can make their own mask using the templates that can be downloaded from HERE. Then I cut a few strips of plastic, to fit these 12 cutouts 2. Unless you feel strongly about it, leave this uchecked. Once printed, attach some self-adhesive felt pads on the msak of the mask the side that will face the corrector to protect the corrector lens. Sripe count must be generwtor positive integer.
Complete cutouts in plastic. Override the slot width here.
Testing larger aperture designs yielded printed masks that were increasingly “off” – also sometimes known as “wrong. Each frame shows a focus difference of In my case I had to print the mask on two pages. Say thanks by giving brentb a tip and help them continue to share amazing Things with the Thingiverse community.
