3″ eyepieces

There are some eyepieces with a 3 inch barrel diameter.

There is a ‘short’ 30mm from Explore – which I saw at a show last year – a monster of an eyepiece.

But there is also a Japanese 80mm eyepiece available from APM – but not cheap – though if you have €2k spare…

Of course you need a scope with a 3″ focuser too…
