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
MOUNT FEATURES
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.
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.
