A fast focal ratio of f/4
This is especially important for astrophotographers dealing with long exposure times. Imaging telescopes made of less thermally stable material can deviate from optimum focus after long time exposures. It can remain in focus for a longer period of time and long exposure images will stay clear and in focus. Tube interiors are equipped with knife-edge ray traced baffles.
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.
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.
The EQ6-R boasts a number of features to aid astrophotographers. The built in ST-4 Autoguider port turns this mount into an astrophotography powerhouse, allowing you to utilize most of today’s best autoguiders. Using the integrated RS232 port, you can control the telescope from your computer and take advantage of today’s most advanced astronomy software. With a weight capacity of 44 lbs, the EQ6-R can handily support an optical tube, imaging accessories and camera.
Silent Yet Precise Slewing
The EQ6-R Pro uses Stepper motors with a 1.8° step angle and 64 micro steps driven. Stepper motors are quieter than servo motors, providing accuracy up to 1 arc minute without waking your neighbors from buzzing motors.
42,000 Object Database
Using our proprietary SynScan hand controller, the EQ6-R Pro provides a user-friendly interface with automatic slewing to over 42,000 objects in the night sky. The hand controller can also connect to a computer using the supplied RS232 cable (USB adapter available), enabling computer control with most astronomy programs. For the astrophotographers looking to reduce Periodic Error, the SynScan hand controller has built in PEC training that can be configured while in the field!
Flexible Polar Alignment
Sky-Watcher includes an illuminated polar finderscope to aid the polar alignment process. The finderscope features a circular grid reticle for the northern hemisphere, consistent with todays popular polar alignment apps. For astronomers in the southern hemisphere, the constellation Octans is built into the reticle as well. Even without a clear view of Polaris, the EQ Pro can be polar aligned using our SynScan hand controller. Simply choose one of the visible stars listed and use the latitude adjustment screws to center it in the eyepiece.
Bundle of Accessories
As customary with all Sky-Watcher products, an assortment of accessories are included with the EQ Pro mount. A retractable counterweight bar is supplied, allowing for easier transportation as well as two 11-lb counterweights are included to help balance any payload. The EQ Pro features a saddle compatible with both D and V style mounting plates, granting users the flexibility to utilize multiple optical tubes, even if the mounting plate is different.
