I am looking for a set of three narrowband filters, 36mm unmounted: Ha, SII, OIII. In good condition. PM me if you have a set you'd like to sell.

I have baader 36mm unmounted - Ha SII OIII, - I will be selling shortly I think as they are vignetting my sensor so I need to get larger filters. Just waiting on a quote from Telescopes Astronomy .
They have only been in use for about a month but are too small for the Tak plus 8300 combo. (have LRGB full set as well)

Let me know when your ready Graham. Not sure about the LRGB at this stage as my budget is limited. I assume the size was no problem for the cameras with the APS-C sized sensor.
Thanks

I think it depends on the spacing from your sensor to the filters. Certainly my previous 8300 cameras ( ST8300 and QSI683) both had 1.5' filters and because they were so close to the sensor it was fine - I have an FLI with 20mm back focus plus an adaptor then a starlight xpress filter wheel on a tak with 44mm image circle.
cheers
