How much the TE10z eyepiece is worth of? (1 Viewer)

Hello everyone,

I am aware that Kowa is not making the TE10z eyepiece anymore, and is only compatible for the 880/770 series of scopes.

I have purchased this eyepiece without doing any home work, whether if this would fit my 824 or not.

I purchased this eyepiece for £350, and was wondering if this can be sold in a similar price range.

Any information in this regard would be useful.

Thanks and regards,
Paul
