The Pocket Borg is probably the world’s smallest quality refractor. This tiny telescope rides beautifully on small table top tripods, and its minuscule footprint eliminates all excuses for not bringing a telescope with you on non-astronomy related trips.The tiny 25mm objective lens secures a view virtually free from false color at this focal ratio.Check out the reviews available online for assessments of the Pocket Borg’s capabilities as an astronomical tool.This package includes a 1.25″ adapter for attaching a star diagonal, as well as an extension tube that transforms the Pocket Borg into a straight-through-view monocular (requires an 1.25″ eyepiece). The integrated 1/4-20 mounting hole makes it easy to attach the Pocket Borg to photo standard mounting accessories. The star diagonal, eyepiece and table-top tripod shown in the photo are not included in this package.

Scope tube diameters are no larger than absolutely required for the light cone, reducing tube weight (but without going to the point of sacrificing stiffness). Lighter scopes themselves make travel easier, but more significantly, they also translate to fewer counterweights and less flexure problems. Borg tubes can also be disassembled down to short pieces, a convenience for packing, especially for airline trips. And optics, including the objective lenses, can be removed so that only the critical components need be hand-carried. (Removable optics have also proven to be a benefit in humid climates where optical components need to be stored in climate-controlled boxes to prevent mildew damage.) Modular design is a strong point of the Borg system. This allows the use of many Borg components across several families of telescope sizes, thus reducing production costs and selling price to the user. This also means more system flexibility to the user. Upgradability was another goal achieved by modularization. A Borg system can start small and be upgraded incrementally as needs change. Even objectives can be upgraded with minimal impact on the rest of the system. Photo-visual design with no compromises was a primary concern of the system designer at Borg, an accomplished photographer with decades of experience. Borg scopes fully cover the 6×7 cm frame of the popular medium format Pentax 67 series cameras, and include photographer’s extras such as a precise, indexed, lockable (two lockscrews) helical focuser and a full range of field flatteners and teleconverters. Also available are a full line of 35mm camera accessories and visual adapters. Wide accessory selection is another distinguishing feature of the Borg line. Adapters for virtually all popular accessories (1-1/4″, 2″, SCT, many 35mm and medium format cameras) are available.
