I have a Baader 2" OIII filter, round, mounted for sale. It is a visual filter that can be used as an imaging filter, with a reported bandwidth of 8.2 nm, but listed on the box as 10 nm.

It was purchased on November 17, 2018. I have not had a chance to use it. I have the original case and packaging. Here is the website for details on the filter:
https://optcorp.com/...la-filter-2inch

"The Baader O-III perfectly isolates the two doubly ionized oxygen lines (496 and 501 nm), through a very sharp and narrow bandpass (8.2 nm wide, the narrowest of any O-III filter!). Unlike other O-III filters, the Baader O-III completely blocks longer and shorter wavelengths (ever wonder why some O-III filters appear red, instead of the correct 500 nm Teal color?). The result is the highest contrast achievable in an O-III filter." (quote added for reference)

I paid $189 for the filter, I am asking $150 shipped. If using PayPal, please add 3.5% ($5.25) for fees.

This is a brand new filter!
