Worked as expected

Fits perfectly on my 8 inch newtonian telescope. I expected it to be made out of metal but it seems to be made out of plastic, which is understandable with the very low cost of it compared to other bahtinov masks. First object I focused on using it was venus, which allowed me to get very good focus without a lot of hassle.

Works as advertised.

Seems to be a well made Bahtinov mask. This is the third Farpoint focusing mask I have owned, so I knew what to expect. I am using it on a 10" Ritchey?Chrétien telescope and it works great.
