I have for sale my Astronomik 2" CCD filters.
They are:
LRGB set Type 2 (4 filters; R, G & B plus clear L filter)
$500 including express Post
SII (Sulphur II) Narrowband 12nm
$275 including express post
OIII (Oxygen III) Narrowband 12nm
$275 including express post
I am keeping my Ha filter
All filters are used, but boxed and in as-new condition. They have been installed in an STL internal filter wheel for use, that is all.
Big savings over new prices.
If you need any more info, please let me know.
Thanks - Rob
