Telescope Esprit ED 120/840 AZEQ6 DS GOTO SkyWatcher

TUBE FEATURES

Esprit 80ED, 100ED, 120ED and 150ED Super APO refractors have a doublet field flattener to get a flat field and minimize aberration and distortion. Their wide 48mm opener ensures a larger and clearer aperture and also extremely minimized halation. Connect the triplet and doublet field flattener with a high precision thin thread to keep the optical axis perpendicular to the image. 

Main Features: 

- Premium optical materials 

- Short focal length and full frame corrected focal plane 

- Excellent field flatness 

- Precision linear power focuser is standard 

- Metallic high-transmission lens coatings 

- Light-baffled optical systems 

- Telescope tube attachment hardware 

- Zero detectable Colour Fringing even on Bright Objects

- Knife-edge Baffled Optical System

FEATURES MOUNT

The Sky-Watcher AZ-EQ6 SynScan mount gives optimal stability and pointing accuracy for a wide variety of heavy professional photo and video equipment. It is a hybrid mount with alt-azimuth capability for general use and equatorial capability for astrophotography use. Supplied with a SynScan handset with dual AZ/EQ firmware, it can automatically find and track 42,900+ celestial objects with its database.

AZ-EQ6 SynScan is capable of carrying heavy-duty photographic equipment for professional shooting and video recording. It is a very efficient transportable mount weighing only 15 kg, for a load capacity of 20 kg (counterweight excluded).

Freedom Find™ - tracking made easy!

With the patented Freedom Find (dual-encoder) technology which allows the telescope to be moved manually or electronically in either axis without losing its alignment or positional information. After moving to a new object the telescope will automatically begin to track the new object accurately. No re-setup is required in one observing session.

German Equatorial / Alt-Az dual mode

Permanent periodic error correction(PPEC). PPEC can be trained with Autoguider or PC.

Belt drive - Super smooth PE curve. Low backlash, silent slewing. 

DSLR Electronic Shutter Release Port for batch exposures of astrophotography.
