View Full Version here: : Low profile 2" to 1.25" adapter required

I just bought a William Optics 2" 45-degree erecting diagonal. Unfortunately, with my ZS80 there isn't enough in focus for most of my eyepieces. I think the tubes of the newer scopes are shorter (relative to focal length) than the old models, and since this diagonal is a new item, it doesn't quite work straight out of the box with my scope.

What I need is a 2" to 1.25" adapter that doesn't raise the eyepiece above the height of the diagonal's 2" barrel. In fact, I've seen some websites in the US where the adapter actually lowers the height of the eyepiece a few mm, which is probably what I need.

Anyone know where I might find such a thing in Australia?

Thanks

Morton

Not sure about Australia but Scopestuff (http://www.scopestuff.com/ss_npea.htm)has something like that.

I've got a GSO dielectric diagonal (2") that came with a low profile adaptor. I bought it from Andrews. It was only $90 including the adaptor. They may sell the adapter on it's own.

That might be just what I need. Thanks!

Ooops! In my haste to be of assistance I forgot to mention that the low profile adapter relies on a cut-out in the diagonal for the 1.25" clamp screw to slot into. On a standard adaptor the clamp screw sits above the top surface of the diagonal. Because the low profile one is actually recessed there is no where for the clamp screw to go except through the 2" section of the diagonal.:doh:
