I'm selling a pair of nebula filters with SCT threads: Meade's #911X O-III filter and #911N Narrowband Nebular filter, both for $175 shipped by insured Priority Mail in the US, payable by PayPal only, please.
These filters are in excellent shape, but I did notice two small specks on the narrowband glass, and one on the O-III glass. I don't think these will interfere in any way with your viewing, but I did want to mention it now rather than disappoint anyone expecting total perfection! I hadn't noticed anything amiss with them the few times I used them with my LX200. I bought both filters brand-new myself, but don't own the LX200 anymore or else I'd be keeping these!
Thanks for looking!
