Some time ago, I remember seeing an adaptor/eyepiece, which attached to your telephoto SLR camera lens, to convert it to a telescope.
The magnification was focal length/10.
I have a very high quality Pentax (K mounting) 80 -200mm lens, which would potentially make a very good 8x - 20x telescope.
Unfortunately, I can no longer find the eyepiece advertised (still looking).
It is clear however, from my first aquaintance with this forum, that many of you are well into adaptors for telescopes/cameras, so it seemed logical that someone might know something about this particular fitting.
If you do, I would be pleased to hear from you.

Best regards to all

There was a short thread on this a little while ago, you can see it at http://www.birdforum.net/showthread.php?t=17433. I must admit I don't recall seeing a Pentax one on eBay (they currently have a couple of Minolta ones for sale). I did find this page - http://www.bdimitrov.de/kmp/lenses/#adapters - there's one shown for K-mount lenses (it's mentioned near the bottom of the page), but I haven't seen one for sale.

If you try a Google search most people seem to spell them adapters rather than adaptors.

Thanks BrianB
I'll follow up your suggestions
Interestingly, adapter is the correct general spelling, but adaptor refers specifically to something which allows the interchange of lenses in a camera. However, as the web rules, I guess I will have to use the general form.

Cheers
