Astronomik 1.25 CCD imaging H alpha and OIII filters
I have not used these recently as I now image with a 2 inch filter and a QHY 8
I purchased both these filters from Bintel
https://www.bintelshop.com.au/welcome.htm
the H alpha filter is the 13 nm version

this is the OIII filter

both have been used in imaging with a modified DSLR.
(the OIII was also used by me with an unmodified DSLR)
excellent condition..well, there is nothing to wear out and I have handled with care . Note these are imaging filters not the ones recommended for visual use
asking for $155 each (including postage)
PM if interested please
thanks
