GENERAL FEATURES
11“ EdgeHD optics CGEM II computerized equatorial mount Celestron’s premium StarBright XLT coatings provide maximum light transmission A 9x50 finderscope, 2” mirror diagonal for more comfortable viewing, and wide-angle 23 mm Luminos 2" eyepiece are all included EdgeHD FEATURES
EdgeHD aplanatic, flat field SCT optics for pinpoint stars to the
edge of the largest imaging sensors and widest eyepieces. Lightweight
and portable Aluminum optical tube with tube vents featuring an integrated
95-micron mesh filter allows hot air to be released from behind the
primary mirror. Mirror support knobs hold the mirror in place and reduce
image shift during imaging Versatile design accommodates 3 focal ratios: native f/10, f/7 with
the addition of a focal reducer, or ultra-fast f/2 imaging with a
removable secondary mirror and third-party accessories COMPUTERIZED MOUNT FEATURES
40 lbs payload capacity Dual-fit Vixen/CG-5 and Losmandy/CGE dovetail saddle 2" steel legs with height index marks for quick leveling USB 2.0 port on hand control for direct links to a PC via ASCOM supported software. 40,000 object database with over 100 user-definable objects and expanded information on over 200 objects Internal cabling throughout for worry-free remote operation Low cog DC Servo motor with integrated optical encoders offer smooth, quiet operation Able to track past the meridian allowing seamless imaging Permanent periodic error corrections allow users to train out the
worm gears periodic errors once, while the mount retains the PEC
recordings. Software Features include: Mount Calibration, Database Filter
Limits, Hibernate, five Alignment Procedures, and user-defined slew
limits Built-in polar alignment program to polar align on any star in the sky Longer clutch levers to make tightening and loosening of clutches easier Custom database lists of all the most famous deep-sky objects by name and catalog number Solar System alignment method allows to view the moon and planets during the day Custom Rate 9 feature allows to set maximum slew rate Tandem mode allows to star align the mount even when positioned for tandem scope use USB hand control to control the telescope via a personal computer Includes NexRemote telescope control software, for advanced control of telescope via computer Precision machined 40 mm diameter steel Polar shafts supported by multiple tapered roller bearings and ball bearings GPS-compatible with optional SkySync GPS Accessory Introducing the EdgeHD Telescope Series, Celestron’s new flagship telescope line...
Ergonomic Design - The Celestrom CGEM-II mount was designed to
be ergonomically friendly with large Altitude and Azimuth adjustment
knobs for quick and easy polar alignment adjustment. The internal RA and
DEC motor wiring provides a clean look and an easy and trouble free set
up.
Innovation - The Celestron CGEM-II series has a new innovative
Polar alignment procedure called All-Star (patent pending). All-Star
allows users to choose any bright star, while the software calculates
and assists with polar alignment. Another great feature of the CGEM
91526, sure to please astroimagers, is the Permanent Periodic Error
Correction (PEC) which will allow users to train out the worm gears
periodic errors, while the mount retains the PEC recordings.
Furthermore, a new dual saddle has resulted in this stellar mount having
the capacity to mount either CGE-Pro style Dovetails or CGE-5
Dovetails.
Performance - For objects near the Meridian (imaginary line
passing from North to South), the Celestron CGEM mount will track well
past the Meridian for uninterrupted imaging through the most ideal part
of the sky. The CGEM 91526 mount has a robust database with over 40,000
objects, 400 user defined programmable objects and enhanced information
on over 200 objects.
Celestron's CGEM-II mount is the perfect fit between the Advanced
Series and CGE Series. Offering the portability of the Advanced Series
and the precision of the CGE.
