TUBE FEATURES
The Sky-Watcher BKP 250 OTAW-dual speed Newtonian Reflector incorporates the same superb mirror-set as the Sky-Watcher Black Diamond 250/1200 OTAW Series, but with two significant advantages. A Dual-Speed 10:1 ratio focuser is now included for excellent focusing precision. Also, the tube length has been slightly shortened to optimize performance for prime-focus photography. Even better performance for astrophotography and visual use can be achieved when used in combination with Sky-Watcher
MOUNT FEATURES
2'' Dual-Speed Linear Power Focuser
The new linear power focuser utilises 4 precision ball bearings to support the drawtube and provide great stability and zero image shift while supporting a heavy eyepiece or camera. Moving the drawtube by the roller rather than a rack and pinion ensures exceptionally smooth operation and precise adjustability. The dual-speed feature has a second focus knob that has a 10:1-speed reduction to provide the super-fine adjustments even the most demanding users can appreciate.
Quality Mirror
It features paraboloidal primary mirrors made of Low-Expansion Borosilicate Glass resulting in substantially shorter cooling-down times.
It comes with an impressive 0.5 mm Ultra-Thin Secondary Mirror Support and it is 77% more Light-Gathering than 150mm.
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.
