SharpStar 71SDQ Quadruplet Apochromatic Refractor Telescope - Flatfield Astrograph

The ultimate portable astro photo and nature photography instrument!

FOR FULL-FRAME IMAGING!

SharpStar 71SDQ telescope features:

• 71MM f/6.3 four-element full separation optical design
• Includes one Super ED Japanese lens
• Flatfield performance (no need for field flattener due to the optical design...)
• New 2" dual-speed rack and pinion focuser, 10:1 fine focus
• 2" and 1.25" universal interfaces
• Angle adjuster for 360 degree rotation
• Universal (Vixen-style) dovetail bar with tube rings
• Comes with a finderscope shoe

Based on the enormous success of the 65Q, SharpStar now launched their latest gem, the 71SDQ to meet the increasing demand of fans.
 
The 71SDQ adopts a four-element fully-separated structure. One of them is a Japanese brand of Super ED glass with a focal length of 450 mm, focal ratio F6.3, the focal plane is 145 mm from the end face of the 360° rotation adapter. The enormous back focal distance provides ample space for any visual or photographic equipment. It can also be used to connect 1.25" or 2" zenith mirrors (diagonal mirrors) and corresponding standard eyepieces available through our website, making the 71SDQ a multi-purpose star observation and imaging APO telescope.
