OVERVIEW
General Features
- 11" RASA optical tube assembly
- CGX computerized equatorial mount
Astrograph Features
- Ultra-fast, 11-inch f/2.2 optical design with rare-earth glass for images free of false color, coma, and field curvature. Cuts imaging time by more than half
- Expansive 43.3 optimized image circle maintains pinpoint stars to the far corners of even the largest astroimaging sensors, while the usable field extends even further to 52mm for larger format sensors.
- Custom engineered linear brass focuser bearing reduces image shift, while dual-speed 10:1 FeatherTouch Micro Focus Knob provides the most precise focusing
- Quiet, high-output 12V MagLev fan reduces cooldown time and blocks dust
- Common camera adapters (T-thread and M48) included for easy attachment to popular CCD and DSLR cameras
Computerized Mount Features
- All-new design. Sturdier and more rigid with quicker dampening time
- Increased load capacity to 55 lbs.
- Improved motors provide more torque, better slewing and tracking under heavy loads
- Heavy Duty belt-drive system minimizes backlash while providing smooth motor operation under heavy loads
- Spring-loaded brass worm wheel and stainless steel worm gear reduce friction and provide optimum gear mesh
- Internal cabling for worry-free remote operation. Power input and accessory ports remain stationary while the mount slews to avoid snags
- Internal hard stops for both axes prevents cable tension and tripod strike
- Internal optical sensors on both axes for simple and safe remote operation
- Home sensors allow the mount to always start in the index position regardless of orientation before a power reset
- Limit sensors automatically shut off slewing or tracking before reaching the hard stop fail safe
- Brand new control software developed in conjunction with PlaneWave Instruments for professional level control operation and imaging
- Software includes multi-point mount modeling for extremely precise pointing accuracy and many more additional features for remote astroimaging
- Wider tripod stance for improved stability
- Adjustable EQ head position to optimize center of gravity over the tripod and fully utilize the increased 3º-65º latitude range
- Dual-fit CG-5/Vixen and CGE/Losmandy dovetail saddle
Improved tripod includes:
- 2" steel legs with height index marks for quick leveling
- "Jack of all trays" can hold three 1.25" eyepieces, two 2" eyepieces, your smartphone, or other accessories
- +20º of additional tracking past the meridian on either side
- Tripod legs can be collapsed with accessory tray installed for faster setup and transport
Improved ergonomics:
- Two handles for easy pickup and transport
- All-new ergonomically designed dovetail clamping knobs
- Innovative and improved polar alignment adjustment system
- All-new ergonomic latitude adjuster for smooth and easy adjustment under full loads
- Optional add-on polar axis finderscope - coming soon
