Has anyone tried using the 1.6 EX16S extender (the one for the 663) with an 823? According to the Kowa website it will work "in combination with a TSN-EC1A adaptor fitted onto the Kowa eyepiece (see: https://www.kowaoptic.com/media/pdf/f2/9b/b4/Kowa-System-S-A4-English.pdf).
I have the adapter and eyepiece, but am a bit dubious as to how the extender will attach to the 823, given that the threads where I assume it screws onto (where you attach the eyepiece cover) are a different diameter on a 663 etc and an 823. The 823 is wider.
Anyway, has anyone had a go with this setup?
