I have for sale my three Narrow Band filters. All filters are in very good condition. They are Ha, SII and OII, 13nm Astronomik 1.25". They are currently in the filter wheel I have for sale in the camera section.

I am asking $400 for all three plus p&h
SOLD
I also have a Bintel 2" 0.5 focal reducer which suits smaller chip cameras. I believe this to be the same as the GSO reducer.
I would like $40 for this plus p&h.
