Trade my Astronomik 2" SII filter for your H-Beta?

Anyone interested in a change to their narrowband imaging?

I have a 2 week old (as new) Astronomik SII CCD filter that is currently inside my STL11000M filter wheel. Looking for a direct swap for a 2" CCD H-Beta filter.

Must be CCD variant, not the visual one.

Anyone interested?

Regards,
Rob

Just to clarify, this is for a TRADE only. I am NOT selling my filter so please don't ask.

Regardless if a trade goes ahead or not, I need three filters for tri-band imaging!
