Farpoint Adjustable Bahtinov Focus Mask — 3.5" to 6.5" OTAs

Bahtinov Mask

Looks good. Well made. Have not tried it yet. Should help with my old (Jason) 4.5” reflector telescope.

Effective, inexpensive tool

This is an effective, inexpensive, and now essential tool for easily and regularly achieving sharp focus when using my DSLR and various larger aperture lenses for photographing the night sky.

Missing parts

The Bahtinov mask I ordered was to have had rubber grommets but received the part without any. Contacted customer service by phone and email and finally received an email a week later promising to ship the missing grommets......still waiting.
