WTB: Orion O-III filter...OR ?
Hello avid astronomers!

I am currently looking for a 2 inch Orion O-III filter.

Let me know if you are willing to sell me yours!

PS: A 2 inch Orion Ultrablock, or a "second" DGM NPB will also suffice.

ONLY interested in 2 inch versions. Not interested in the DGM / Omega O-III as it is not a good performer for an O-III filter.

*NOTE* Please send pics!

Thanks for looking!
Price: $1
