Refrator apocromático AP 70/420 ED V2 OTA

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 Field flattener for PhotoLine apos ,72mm, 1.0X The focal length and aperture ratio are not changed. The corrector is ideal for DSLR cameras and CCD cameras with larger sensors. The recommended working distance from the M48 thread is 55 mm. The flattener is screwed directly to the M54 connection thread of the focuser.
• TS Optics Reducer Flattener Photoline 0,8x 2" for 80ED f/7 APO This corrector is actually designed for the 80 mm f/7 ED. But it also performs well at 70 mm f/6. The focal length is shortened to 336 mm and the speed increases to f/4.8. We recommend a working distance of 63 mm to improve the correction factor. Adapting a DSLR camera is easy, all you need is a T2 extension tube with 8 mm (TS Optics Cilíndro de extensão T2 extension tube, 8mm optical path) and the matching T2 ring.

TS Optics Dovetail Mounting Base for Finder Scopes Deluxe 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.
