Description

The Levenhuk Ra FT72 ED PhotoScope is an apochromatic refractor for astrophotography. This telescope can be used as a spotting scope as well as a camera objective lens. It can be used to observe space, but the main purpose of the telescope is photography. Due to the extra-low dispersion optics and eyepiece that efficiently collects light, this telescope renders a highly contrasting image with a minimum of chromatic distortion. The kit also includes an aluminum case that makes the transportation and storage of the telescope easier.

The Levenhuk Ra FT72 ED’s main feature is a 2" helical focuser. It is robust and allows for very accurate focusing and smooth movement without backlash. It provides crisper and sharper images than a rack and pinion focuser or even the more advanced Crayford focuser can provide. It is also compatible with heavy accessories.

The optical tube has a standard 1/4" thread, so that it is compatible with the most of modern mounts and tripods. To install a SLR camera, you need a special adapter, which is not included in the kit.

Features:

  • Apochromatic refractor with extra-low dispersion optics
  • Fully multi-coated lenses render the brightest picture
  • Minimum chromatic distortion, wide field of view, and high contrast
  • Helical focuser provides precise focusing
  • Suitable for professional astrophotography
  • Compatible with 2'' accessories

The kit includes:

  • PhotoScope
  • Cleaning wipe
  • Aluminum case
  • Focuser protective cap
  • Eyepiece protective cap
  • User manual and lifetime warranty
