I'm selling my set of Baader 36mm Narrowband filters as they are now surplus to my needs. The set consists of:
- Baader 36mm round unmounted 8nm SII filter
- Baader 36mm round unmounted 7nm Ha filter
- Baader 36mm round unmounted 8.5nm OIII filter
They are in great condition. I've only handled them twice, once to put them in my FW and once to take them out. I've only cleaned them with a bit of compressed air, never wiped them.
I'll sell them for $450 plus postage.
You can find a couple of images I've taken with these filters, from urban Sydney, here:
