Celestron has been in the forefront of computerized telescope technology for over two decades. We have taken this expertise in telescope technology one step further by introducing the NexRemote™ Telescope Control Software. NexRemote allows the user to control their Celestron computerized telescope from their personal computer. Everything that is done using the telescope’s hand control can now be done remotely from a PC or laptop. This software was developed for Celestron’s high-end telescopes that use the NexStar control system including the NexStar "i" Series, Advanced Series, NexStar GPS Series and CGE Series.

NexRemote provides full emulation of every aspect of the Celestron Computerized Hand Control including:

  • Alignment in any tracking mode
  • Database of objects
  • User objects
  • Hibernation
  • Connect to popular planetarium programs

NexRemote began shipping in March 2005 with select high-end computerized Celestron telescopes including NexStar i Series models, NexStar GPS models and CGE models. Contact your Celestron dealer to find out availability of upgraded models that include NexRemote. Software will also come with an RS-232 cable to connect your Celestron telescope to a PC. For those who already own a compatible Celestron computerized telescope and want to take it to the next level of convenience and enjoyment, the software can be purchased separately as a kit through an authorized Celestron dealer (item# 93710). Kit includes the NexRemote software & license, RS-232 cable and a Serial-to-USB adapter.

Celestron CGE Pro Mount
n addition to being fully computerized with a database of over 40,000 celestial objects, the New CGE Pro German Equatorial mount has been completely redesign to offer numerous design advantages for the Astrophotographer:

Increased Payload Capacity
Able to hold our 14" SCT telescope more securely as well as larger optical tubes up to a maximum instrument capacity of 90lbs (not including counterweights).

All-Star Polar Alignment
Choose any bright alignment star for a software assisted alignment of the mounts polar axis that will have you ready for imaging even if you can't see the North Star.

No-Tool polar alignment
Larger hand knobs for both Altitude and Azimuth adjustments.

Meridian Tracking
Extended tracking past the Meridian of up to 20 degrees of uninterrupted imaging through the best part of the sky.

Faster slew speed
Improved gearing and motors provide faster slew speeds than ever before with a maximum slew rate of over 5°/per second.

Power Management
Redesigned electronics deliver constant regulated power to the motors making them capable of driving the telescope even when not perfectly balanced. This allows the CGE Pro to have the payload capacity of that of much larger (and expensive) mounts without sacrificing smooth tracking motion and pointing accuracy across the entire sky.

The hallmark of any telescope mount is its ability to find, center and track celestial objects with the highest degree of accuracy.

With just a standard hand control alignment, CGE Pro has the ability to center a star in your eyepiece or ccd chip to within 5 arc minutes. Using NexStar's advanced pointing features such as Calibration Stars, Sync and Precise GoTo, further improves the pointing accuracy to as low as 1 arc minute in the desired region of the sky.

With larger .75" pitch diameter worm, precision made cut-steel gears in gearboxes, and seven slot skewed armature motors the CGE Pro delivers typical tracking performance of +-9 arc seconds, which can be further reduced with the mounts permanent periodic error correction (PPEC).

Mount Modeling
Celestron's NexStar hand control has built-in mount modeling features essential for accurately placing small objects on the center of your ccd chip or high power eyepiece. Aligning on multiple Calibration Stars creates a mathematical model of the opto-mechanical inaccuracies inherent in all equatorial mounts. This model is stored within the hand control and is used to compensate for these inaccuracies thus improving your pointing precision each time you slew your telescope.

And of course the CGE Pro is also fully T-Point compatible (available from Software Bisque) for ultra precise pointing across the entire sky.

In addition to these improvements, the Celestron line of German Equatorial mounts has long been recognized for features preferred by visual observers and astrophotographer alike. Among them include:

Portability - Set up and transportation of the CGE Pro telescopes is made easy by separating the mount into smaller, easy-to-carry components. Unlike fork arm mounted telescopes, the CGE's optical tubes can be quickly removed from their mounts making even the CGE Pro1400 easily assembled in minutes.

Stability - Recognized for superior stability, German Equatorial mounts place the center of gravity directly over the tripod legs and can be easily polar aligned without the use of an optional equatorial wedge. This proven design reduces the "tuning fork" vibration that can be associated with undersized fork mounts. An improved Super HD Tripod supports the CGE Pro mount. This fully extendable tripod is made from the finest 2.75" stainless steel and can be raised to a height of 55". The tripod uses a dual leg support for maximum rigidity with an upper leg brace to provide an outward preload and a lower leg brace providing inward tension.

Balance - CGE Pro equatorial mounts can easily be balanced in both axes. Simply sliding the counterweight for Right Ascension and moving the optical tube along its dovetail mounting for Declination accomplish balancing the weight of camera equipment and other visual accessories. This means that no additional weight needs to be added to balance the telescope when additional accessories are added.

Clearance - CGE Pro mounts support their tubes at a single contact point allowing the tube to move freely around its polar axis without making contact with the telescope's mount. Software features allow the user to set the mounts slew limits to guaranty safe motion.  This is particularly useful when adding photographic and CCD instruments that extend from the rear of the telescopes.

All CGE mounted telescopes are compatible with Celestron's CN-16 GPS accessory. Combine the GPS and built-in real time clock and these telescopes will keep track and remember their exact location and time without having to enter the information into the hand control.
