DESC: Its 102mm, fully multi-coated front corrector lens renders the rings of Saturn in razor-sharp detail and coaxes out the gaseous tendrils of the Orion Nebula. And with its 1300mm focal length (f/12.7) it has the same magnification range (up to 200x) as longer, bulkier refractors in a tube less than 12" long! T-threads on the eyepiece adapter enable direct attachment of a 35mm camera body (with optional T-ring) for short-exposure shoots.
