I only have one eyepiece capable of using 2" filters, and it doesn't get used that often. Not often enough to justify keeping these superb filters. I use my 1-1/4" Astronomik filters instead.
Anyway, here is a nice 2" UHC & 2" O-III.
H-beta - 96%
O-III(496nm) - 96%
O-III(501)nm - 94%
O-III(496nm) - 97%
O-III(501nm) - 96%
H-beta - .08%
It doesn't get much better than this on the transmission.
The glass and coatings are perfect, neither has ever been cleaned.
The UHC is in an nicer aftermarket case, the O-III is in its original case.
$165 each and I'll pay the shipping and Paypal fees.
(Shipped in the continental US only)
This is a firm price, so don't ask if I'll take any less because I will not.
