Which adapter does what
Binoculars on a tripod
The Alpen and Athlon binocular tripod adapters put a tripod-adaptable binocular, one with a threaded socket at the front, on any tripod with a 1/4-20 screw, for long, steady viewing.
Cameras and correctors
The T2 reduction adapter joins the M48 and M42 threads, and the 2-inch T2 camera adapter fits a DSLR to any 2-inch focuser with a camera-specific T-mount. Two more adapters fit the FFFR507X-00 3-inch flattener and 0.7x reducer to a 2-inch focuser, or to the 2.5-inch hex focuser on Explore Scientific's 127 mm APOs.
Mounts and finders
For the iEXOS-100, the azimuth adjuster adds smooth, repeatable control for polar alignment, and the polar finder kit adds the illuminated polar scope the mount lacks. The giant binoculars finder adapter carries a Hybrid 2N1 finder base on Explore Scientific's giant binoculars, for easier pointing.
Phones and stocks
The Hawke Digi-Scope adapter holds a phone 66 to 95 mm wide to an eyepiece 33 to 60 mm across, for photos and video through a spotting scope, binocular or monocular. The Athlon Saddle Mount, at 3.5 oz, clamps a stock of 1.1 to 2.6 inches to an Arca-Swiss head or a 1/4-inch thread.
