Sharp Guide 70 télescope

With a useful aperture of 70mm and a focal length of 400mm (F5.7), it lends itself well to focal lengths up to 1500 / 1700mm.
The air-spaced doublet is FMC-treated and thanks to the not-too-high focal ratio, the chromaticism is minimal, which makes it both a traveling and a telescope using (optional) a rectifying prism
In addition to the helical focusing device, a threaded ring near the doublet cell is used to extract the back focus and allows the use of a bend or other accessories.
The equipment includes a pair of rings and a plate compatible with the supports for the find scope Sky Watcher, Celestron, Orion, GSO, etc.
On the tube there are also 2 threaded holes to directly screw a dovetail and have a more solid support both as a telescope guide (not removable) or as a travel telescope.

Characteristics:

- spaced doublet air and treated FMC of 70 / 400mm
- Weight 1260 grams
- SW-type shank and fixing rings
- Long back focus excursion for use with bend and rectifiers
- micrometric helical focuser
