Product description

This ED refractor is an ideal telescope for travel and mobile use. The telescope weighs only about 2 kg and thanks to the retractable dew cap it is only 30 cm short.

The high-quality 2-element objective provides sharp and high-contrast images and enables magnifications of up to approx. 180x. With it you can already observe details on planets. The newly developed 2" RAP (rack and pinion) focuser is superior to standard Crayford focusers and holds even heavy photographic accessories safe. The micro-reduction is ideal for astrophotography and allows precise focusing.

The precise focuser and the powerful optics make the 70 mm ED a good telescope for astrophotography. Connect your SLR camera or astro camera to the telescope and start the adventure of astrophotography. In order to correct the image field for the photography of nebulae, star clusters and galaxies (deep-sky photography), we recommend correctors:

TS Optics Sucherschuh universal This viewfinder shoe fits directly on the focuser. Here only one of the two M4 blind screws has to be unscrewed. The finder shoe is then fastened with an M4 countersunk head screw.

The flexible plate at the base makes mounting easy. You can mount the refractor like a spotting scope or telephoto lens directly on photo tripods. With the matching dovetail bars you achieve a stable attachment to altazimuth and equatorial mounts.
