Finally got around to putting this clear filter on my old ASI camera and the low profile design means it doesn't poke out past the nosepiece at all. Threads were smooth and snug on the first try, and now I don't have to stress about dust landing on the sensor between sessions.

The 1.25" threads screwed onto my older ASI camera without any fuss, and the low profile design means it doesn't stick out awkwardly in my setup. Dust has stopped being a constant worry since I put it on, and the clear glass doesn't affect my imaging at all.

Finally, a clear filter that actually fits my older model without needing extra adapters. The low profile design is perfect for keeping my optical path short and avoiding vignetting. Super easy to screw on and forget about.
