Farpoint Bahtinov Reviews
Great quality..., but some issues.
Product quality is excellent. These masks are a MUST HAVE in getting an easy and precise telescope focus on night-time stars. However, my 'scope uses two different focusing masks. The description of them was confusing causing me to order the wrong one which now doesn't fit properly. Being a lower value item and me in another country it's not worth returning it so I'll just live with using it as is. My other concern is that once the mask is installed onto the 'scope it's extremely difficult to remove. To remedy this I installed two sets of plastic hardware (screws, washers and nuts) on opposite sides of the mask as a means of removing the installed mask. It then works great. Why doesn't the manufacturer do this?
