Filtre V-Bessell

I’ve been using this green photometric filter for a few weeks, and the high-transmission coating really makes a difference—images come through noticeably brighter than my old filter. It’s solidly built, too, no flimsy edges or coating wear after repeated swaps.

I’ve been using this green photometric filter for my telescope’s UVBRI setup, and the sputtered coating seems to handle light transmission really well. It’s sturdy, and the visible band is crisp enough for my deep-sky observations.

The coating on this filter feels exceptionally durable, and it snaps into my filter wheel with a satisfying click. My test images show noticeably cleaner green channel data compared to the old filter I was using, though I wish it came in a slightly thinner cell.
