Hi all,
Selling a set of 36mm unmounted Optolong narrowband (Sii, Ha, Oiii) filters.
36mm filters suit all sensor sizes up to full-frame.
More Info:

Sii (
6.5nm bandpass, CW = 672nm, T = 87%)
Ha (
7.0nm bandpass, CW = 656nm, T = 83%)
Oiii (
6.5nm bandpass, CW = 500nm, T =82%)
They come in their original boxes with original transmission curve datasheets.
They are in perfect optical condition, no scratches, and have never been bumped or dropped. They've been living inside the sealed filter wheel ever since I opened them up
They are perfect entry-level narrowband filters, and at 6.5nm they have allowed me to shoot even on moonlit nights from my bortle 6 suburban home!
I am asking
$450 for the set
including shipping within Australia. I am not willing to sell them separately for the moment but may be open to it if the set doesn't sell.
Stefan
