I am letting go of most of my visual eyepieces as I am mainly imaging these days and they are not getting used at all. The one I am offering here is a very nice 13mm by Baader Hyperion in as new condition. It is fully modular, multifunction, with a bottom 1 1/4" element that unscrews to convert it to a 2" 26mm EP. It comes with an M42 to T thread adaptor and can be setup for afocal photography (camera attached to the eyepiece). You can view details of this nice EP here:

I have had it for about three years but it has rarely been used and lived in my padded EP case. Lack of use was not due to the EP as it is excellent and has a 68 degree field of view, but it was bracketed in size by Televue EPs.
I paid over $200 for this one, but I see they are selling new at the overseas retailers for $147 USD, plus shipping, and I have seen them in Australia for over $200 AUD. I am offering my Baader Hyperion 13mm, with all the parts shown in the photos, for $120 AUD and $15 for shipping anywhere in Australia.
PM me here at IIS if your interested in this eyepiece.
