71mm f/4.9 Quadruplet APO Refractor Telescope - Ultimate Astrograph for Grab-and-Go Astro Photography - 71mm aperture / 347mm focal length / 45mm well corrected and illuminated field diameter

Five elements in three groups. APO telescope with perfect field correction for astrophotography - 2.5" Dual-Speed Rack and Pinion focuser - FPL53 triplec objective

This apochromatic refractor is ultimately designed for astronomers who want the best results in photographic/CCD imaging. The TS Imaging Star 71 provides pinpoint stars even at the very edge of a 45mm imaging circle.

  • The Imaging Star 71 mm f/4.9 Imaging refractor is one of the best telescopes for astrophotography, we've ever have seen.
  • The telescope is highly portable. Weighs only 2 kg and is just over 320 mm long. This telescope can go anywhere including under an airplane seat! It´s a great grab-and-go scope for the digital astrophotographer.
  • The optical design of the Star71 is a very new design using five element FPL-53 fluorite glass in three groups to produce color free, pin-point images across a 45 mm flat field. No flatteners or reducers are needed.
  • A heavy- duty 2.5" rack and pinion 10:1 dual-speed focuser is super sturdy and will not slip when locked down, even with heavier cameras attached.

The new 2.5" dual speed R&P focuser holds also very heavy cameras. The focuser offers 360° rotation and a M48 direct camera connection.

The 5-element optical system (3 groups) works more effective than a conventional objective - flattener - reducer design.

For people who want use the apo as a visual instrument, we offer a 1.25" diagonal TSIS-ZS1 which connects directly to the Bajonet of the Apo. The Backfocus is too short for 2" Diagonal.
