Functional but fragile

Doesn't seem to be working much longer though. Flexible plastic with Mickey Mouse, consisting of pins and rubber pads for adjusting and gripping the lens. It's worked a couple of times, but at this price point they owe us solid materials and a reasonable design worth putting in the field.

Pros
  • Bakhtinov focus mask for small telescopes; Suitable for telescopes with a front panel or tube diameter of 2.5" to 4.5" (63mm to 113mm). Easy to install.
