The Nikon #6956 FSB-2 Adapter allows digiscoping with the Coolpix 4600 & 5600 digital cameras and fixed magnification MC series or DS series Fieldscope eyepieces. Fabulous results can be expected.
It is recommended that you digiscope with the newer DS Series eyepieces, because they have a wide, unobstructed eyepiece path and far less chance of vignetting. When using the 40x/50x or 60x/75x DS eyepieces, you will not need any additional attachments beyond this FSB-2 bracket. When using the 24x/30x DS eyepiece, you will need to use the bracket in conjunction with the included FSBR-2 adapter ring, which provides some additional spacing to properly position the camera/eyepiece combination.
If you are digiscoping with the Coolpix 4600 or 5600 and the MC Series eyepieces, you will need to buy the #6952 FSA-1 & 2 Non-SLR Photo Adapter .
The FSB-2 adapter is not compatible with older eyepieces without a helicoid-type eyecup.
As with all digiscoping efforts, you'll need a sturdy tripod with a video-type pan/tilt head as well as a cable release or remote control for your camera. Logical choices for a tripod/head combination are indicated here as accessories, with an ascending order in price & support.
