Farpoint Adjustable Bahtinov Focus Mask — 9.5" to 12.5" OTAs

Works great.

Perfect for my two 10" astrographs. Fully adjustable and fits perfectly. I use the mask primarily to get perfect focus for my Pegasus SmartEye.

Good value Batinov mask

Good product. Great value. Quick shipping. A+

Kicking myself for not getting one earlier

It's well made and does the job. Focusing is vastly easier with this thing, and without the fuss and expense of a motorized focus.
