The Swarovski DCA Digiscoping Adapter allows you to digiscope with your Swarovski spotting scope, using either a digital point and shoot camera with a 28mm, 37mm, 43mm or 52mm filter specification or an SLR camera and a 30-50mm lens with 52mm filters. In both cases, you capture images through the spotting scope's eyepiece. In addition to the specified filter sizes, you can also use step-up rings and even step-down rings to adapt your lens' filter size to 28/37/43/52mm.
All ventures in the world of digiscoping require the use of a sturdy tripod, first and foremost. Logical choices for a tripod/head combination are indicated here as accessories, with an ascending order in price & support. You must take great care to keep vibrations during exposure to an absolute minimum. Employing a cable release, electronic release or remote control for tripping the shutter is absolutely necessary. And while it is not necessary per se, a mounting bracket will do wonders to reduce vibrations of your rig.
