مرشح سديم O-III 1.25 بوصة (310205)

The view of the Veil Nebula through my telescope really popped once I screwed this filter on. I could see wisps of structure in the Cygnus Loop that were invisible without it, thanks to it passing only those specific oxygen lines. Definitely worth the upgrade for hunting supernova remnants.

The view through this filter on the Helix Nebula was stunning—the two oxygen lines really pop against the dark background. It screws into my 1.25" eyepiece perfectly and the image stays crisp without any weird halos.

I was surprised by how much more detail popped out on the Veil Nebula compared to my old UHC filter—the doublet-peak transmission really isolates those O-III lines beautifully. The 1.25" size threaded right into my eyepiece without any adapters needed.
