My first clear night with it was a revelation—the Bahtinov-style diffraction pattern snapped into focus far more precisely than my old mask ever managed. The finer slits really do make a difference; I could nail critical focus on my scope in under two minutes.

The diffracted spikes on my first test shot were razor-sharp and perfectly aligned. I love how the design makes focusing on dim nebula targets feel almost effortless.

Finally got a clear night to test this mask and the diffraction spikes on bright stars came out razor-sharp. The Bahtinov-style pattern made focusing my telescope on the Pleiades feel almost automatic.
