Introducing our best value for an 11" computerized telescope.
The largest aperture Advanced telescope in the series, this 11" Schmidt-Cassegrain optical system is mounted on the computerized CG-5 EQ mount, which features precision worm gears for extremely smooth motion. And with the heaviest component under 30 lbs this telescope won't break your bank or your back.
The C11 optical system comes with our premium StarBright® XLT coatings and its large aperture offers light gathering power 1593 times that of the human eye and 89% more than our 8" model. An optional polar alignment scope for quick alignment is available.
Mounted on the Advanced GT Series computerized mount, this telescope has some high performance software and hardware features. Operated by our proven NexStar® computer control technology the telescope has a 40,000+ object database with 100 user-definable objects and expanded information on over 200 objects. Custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; variable star; solar systems; objects and asterisms.
Using the RS-232 communication port on the hand control, you can control the telescope via a personal computer and our new flash upgradeable hand controls allow you to update your telescope's operating software via the internet. An autoguider port is also included for astrophotography.
