The NEW 22" f/4.2 UC is a revolutionary design. It is a large aperture telescope that collapses into a very small package. If you have limited hauling or storage capacity, then this is the scope for you.

Our revolutionary Virtual Mirror Box (VMB) is the foundation of the UC design. It is a welded steel framework made from NC laser cut steel. It provides four main functions. It provides the primary mirror cell, the altitude bearings, the connection points for the truss poles, and a retainer for the wheelbarrow handles. To keep it as ultra compact as possible, the side bearing portion is foldable to reduce the height of the VMB by half.

Same premium optics, same enhanced coatings, f/4.2 focal ratio and similar design to the popular 15 and 18 inch Ultra Compacts.
