Off-Axis Guiders End Differential Flexure

The FLI ProGuider is designed as an alternative method for auto-guiding a telescope during imaging sessions. Why use the ProGuider? A guide-scope can be expensive and can introduce differential flexure; A dual chip CCD camera must guide thru filters which makes finding suitably bright guide stars difficult.

The FLI ProGuider Off-Axis Guider has important features that distinguish it from the other off axis guiders.
