Description
The mount is designed to operate in both northern and southern hemispheres at latitudes from 0 to 70. Twin adjustment knobs in the base of the mount let you fine-tune the azimuth alignment on the pole over a +/-8 arc. When using the CEM70ECW mount at latitudes below 10, a few simple adjustments of the unique variable position counterweight shaft lets you change the counterweight bar angle so the counterweight does not bump the tripod during use.
Optical tube mounting method: The spring-loaded mount head has an 8″ dual saddle that accepts both industry-standard Losmandy “D-Plate” and Vixen-style dovetails.
No tripod or pier supplied: Because of the CEM70ECW’s ability to be used with a variety of scope types in both observatory and in-the-field situations, no tripod is supplied. This allows the purchaser to chose from a variety of tripods and piers that best suits their needs.
If you’re looking for a high-precision, high payload capacity German equatorial mount for serious astrophotography and visual observing – yet one that is portable and reasonably priced – take a careful look at the new iOptron CEM70ECW. It may be just what you are looking for.
