Does everything it’s supposed to do. Makes focusing a snap. Only problem was the center hole was too small to fit my Celestron 8se and I had to do a little filing to make it larger.

There are two models of this item, this one does not fit new models.

This product does what it's supposed to i.e. Good tight focus. However, the company needs far better quality control. I should not receive any new product regardless of the price and have to modify it in order for it to work on what it's designed to work on! After about 20-30 minutes of sanding ( wasting rare clear winter sky's mind you ) I managed to get it to fit the 8" SCT that it is designed for. Excellent product, horrendous quality control.

It works just like I've seen described on various websites. It is made of sturdy plastic with some flexibility. The outside diameter fits nicely in my 8" Nexstar evolution SCT. The center hole was a bit small to fit around the secondary mirror holder. But with careful use of a round file, I enlarged the hole for a custom fit.

When used as directed, this mask helps photographers sharpen the focus on their camera for astro photos.
