An Astrophotography Powerhouse The EQ6-R boasts a plethora of features to support astrophotographers in their craft. The built-in ST-4 autoguider port turns this mount into an astrophotography powerhouse, allowing you to use most of today’s best autoguiders. Using the supplied USB-B cable, you can control the telescope from your computer and take advantage of today’s most advanced astronomy software. With a weight capacity of 44 pounds, 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 to the tune of 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 USB-B cable, 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!

The polar scope features a circular grid reticle for the Northern Hemisphere, consistent with today’s 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 EQ6-R 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.
