Description
Focus on more important matters with the aid of a bahtinov mask.
A bahtinov mask produces a distinctive spiked pattern on a bright star - you'll know when the focus is perfect when the third spike moves into the center. No guessing anymore!
Designed to work specifically with the Rokinon/Samyang 135mm F2 lens, using a high bahtinov factor of 100 (higher factor produces a sharper pattern).
What's included:
- 1x Bahtinov mask (93.5mm inner diameter)

Customer Reviews
Before, eyeballing the live preview of my camera got me down to a FWHM of ~3.4 pixels, now with the same setup and the assistance of the Bahtinov mask I am reaching <2.2 pixels! That's a 59% improvement in sharpness! The print quality is superb, no need for me to worry about trial & error with print settings to get it right. Tight fit, which is good. There was a tiny stray strand of filament, but it was easy to brush off and it feels like the thin lines won't snap (unless you intentionally force them to...)
Aun no he probado la efectividad de la mascara
Bien fait, mais pas encore essayé. Système en construction
Great shopping experience, quickly shipped and received. When received the items were well packaged. The product itself is very good quality. I absolutely recommend Astrodymium!
