| Editorial Reviews:
Product Description This version of the popular ShortTube 80 is sold without accessories. It is ideal for use as a guide scope with a CCD autoguider. All air-to-glass surfaces are now fully multicoated, ensuring maximum light transmission for enhanced brightness and clarity. The ST80's 80mm objective doublet lens and 400mm focal length (f/5.0) deliver bright, wide-field images. Only 15-1/2" in length, the ST80 is easily portable. The 1.25" cast aluminum rack-and-pinion focuser has a focus lock knob and a dovetail fitting to accommodate Orion finder scopes. For use as a guidescope, use guidescope rings #7381. One-year limited warranty. Dovetail mounting bar not included.
