Hello,
I am looking for a Polemaster adapter for the AP400. I couldn't find one in the usual shops, so I'd like to ask if there is one planned or if maybe one of the existing adapters fits the AP400.
There is a hole for the polarscope in the AP400 where the Polemaster could be fixed (see the attached picture); it's diameter is 23.5mm.
Regards,
Geras
