Celestron 2" Oxygen III Filter

The Celestron OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects.

Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700 nm This eliminates the un-natural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.

Oxygen 111 filter
I found a open star cluster and when I put the O111 filter in and behold there was a nebula there
I think thay it was the Trifed.
I also found the Logoon nebula nearby.
It didn't help the Orion nebula very much though.
Most of all I like the price of the 2 well below $100.00. You can't beat that.
