Hmmm ... I don't think I've ever seen an eye piece with as long a focal length as 60mm!

My guess would be to try Either Andromeda Optics or Northdown Telescopes.

Or, if you don't have any luck with them, a friend of mine, Gerry Maloney (you might have seen him at a star party near you), does a lot of second hand dealings. I got all my eyepieces from him. You can get him on:

ursa at eircom dot net

He lives in Kells, but posts what you need on the same day.

Again, thats if you don't get any luck with Andromeda Optics.

60mm, that would be some eyepiece,
Just out of curiousity, what kind of scope are you putting that grenade on ??
You might run into problems with certain types of scopes with such a low magnification, for instance, in a SCT you might end up "seeing" the shadow of the secondary (a dark disk) in the center of the FOV if you go too low in mag.

I'd imagine you'd have better luck getting a 40 mm and using the focal reducer on that, this would give you an affective eyepiece of 63.5mm, although you might get vignetting etc.

Dave et al,

The closest example I can think of is the TeleVue Plossl 55 mm which I have. It is one of my favourite eyepieces when used in conjunction with my C14. I get around 75x at native f/11 and provides relatively large fields of view.

Oh yes, it can VERY easily pass like a grenade ... it weighs line one as well.
