Bushnell 15-60x60 Discoverer Spotting Scope "F" mount adapter

Clive Woolls , May 02, 2008; 06:49 a.m.


A colleague has one of these telescopes that can apparently be attached to his D3 but doesn't know what adapter to buy or try and get made.

If anyone knows anything about this subject please stick your hand in the air.

Personally, when he said it offered an equivalent of 1000-4000mm focal length I seriously doubted if he could focus adequately even if he managed to keep things still without casting it all in concrete. But each to his own...

Thanks guys. Clive

Clive, I have never tried this but there are a few photogs who swear by it for birding and wildlife. Some of the images I have seen look decent but then, they are also very small on web pages. If you want more info, check out these guys.......

Sorry, should have said click on "Digiscoping" on the left.

yup, digiscoping's the term. I know nothing of this but came across some kit recently:


It's a UK site but should give you some leads for further research

I have a Baush & Lomb (now Bushnell) 'Discoverer' 15x-60x spotting 'scope. With camera adapter tube and adapter ring, it becomes a 1000mm-4000mm 'lens' on my F2AS. I put 'lens' in quotes because it is pretty poor as a lens. 1000mm is tolerable if that is all you have. Over that is garbage. Not to cut up the 'scope, they are just not engineered for photography. An Astronomical telescope with camera mount is an entirely different animal. You can try a 'scope for a lens, somewhat better than nothing. Good luck. /Clay

By the way, the two parts required are:

Bausch & Lomb (Bushnell) #22-3030 Discoverer Telephoto adapter tube, and Bushnell camera body adapter ring #20-003 for nIkon.


Clay L , May 02, 2008; 08:35 p.m.

OOPs: Adapter ring #20-0003.

And where do you buy one of the those #20-003 adapter rings? Have only found one place off of google, other sites that sell them.
