Details
The popular 6" Newtonian in the Advanced series is now available on our heavy-duty CG-5 computerized mount. The C6-NGT Newtonian scope uses diffraction-limited parabolic primary mirrors for razor sharp star images across a wide field of view. The optics of these heavyduty telescopes are manufactured to Celestron's uncompromising standards with star images that are classic textbook Airy disks.
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. No matter at what level you are starting out, this precision instrument will satisfy your needs both visually and photographically.
CG-5 Mount - Precision engineered for stability.
Our new German Equatorial mount has precision worm gears on both axes for extremely smooth stability. The key element that makes this system the most stable in its class is the NEW heavy-duty tripod with larger and more substantial legs that offer excellent damping characteristics for more stable views. The CG-5 also has a convenient latitude scale for easier alignment and an optional polar finder scope for the ultimate in precision alignments.

All-Star Polar Alignment
All-Star Polar Alignment Technology
German Equatorial Mounts (GEM) have long since been recognized as the mount of choice for astrophotography. Needing to track in only one axis for long exposures; adjustable counterweights and tube position for perfect balance, the GEM has few short comings when it comes to imaging. However accurate tracking still depends on an accurate polar alignment. Even with a visible star very near the North Celestial Pole (NCP), the true celestial pole can be a very elusive place to find without assistance.
Now select Celestron mounts can utilize a new innovative Polar alignment procedure called All-Star™. All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment.
Here's how it works.
Once your telescope is aligned with two bright star, All-Star allows you to choose any bright star listed in the NexStar hand control to assist in accurately aligning your telescope's mount with the North Celestial Pole. Using the telescope's Sync function, the mount is able to point and center a bright star with a high degree of accuracy. Once centered, the mount will point the telescope to the exact position that the star should be if the mount were precisely polar aligned. By simply adjusting the mounts altitude and azimuth controls to re-center the star in the center of the eyepiece, you are actually moving the mounts polar axis to the exact position of the North Celestial Pole.
FAQ
Can I use Polaris to polar align my telescope?
Since Polaris is very close to the NCP and not very bright, it is actually not a recommended star for the "All-Star" method. The advantages of being able to use stars other than Polaris are
two fold:
- Polaris is not always visible. So not only can you use a variety of other stars but they are also brighter and more prominent.
- The star you choose will be farther away from the NCP thus allowing for greater accuracy when centering the star in your eyepiece.
Which stars are best to use for polar aligning?
For best results choose a bright alignment star that is near the Meridian, preferably close to the celestial equator. Try to avoid stars that are close to the west/east horizon or directly
overhead because they can be more difficult to center using the mount's altitude and azimuth controls. Also stars too near the celestial pole are less accurate than those further away.
Will I lose my alignment after I polar align?
No, the mount will retain its alignment but some amount of accuracy may be compromised depending on how much the mount has been moved during polar alignment. Although the telscopes tracking
may be very good, pointing accuracy may need to be improved, especially if you are trying to located small objects on a ccd chip.
What are the steps to polar align my telescope using "All-Star" polar alignment?
- Align the telescope with the sky using the "Two-Star Alignment" method.
- Select a suitable bright star from the Hand Control's database and slew the telescope to the star.
- Press the Align button and select Polar Align => Align Mount from the list.
- The telescope will then re-slew to the alignment star and ask you to center it in the eyepiece in order to "Sync" on the star.
- The telescope will slew to the position that the star should be if it were accurately polar aligned.
- Use the mounts altitude and azimuth adjustments to place the star in the center of the eyepiece and press the Align button.
- Update the telescope's star alignment if necessary.
Motor Control Firmware Updates v.2.2.1
Our latest hand control firmware for computerized goto telescopes, version 4.13, now allows you to update the motor control (telescope mount) firmware through the hand control. Our hand control firmware is still updated by connecting the RS-232 hand control serial cable (part #93920) directly to the hand control, and then to a computer with an internet connection.
Previously, motor control updates were done through the telescope’s PC Port (CPC and CGE series) using our Programming Cable (part #93922). If your telescope did not have a PC Port (Advanced GT, NexStar SE and NexStar SLT series), you would also have needed our Auxilliary Port Accessory Kit (part #93965)
Our NexStar SE and CPC Series already ship with the RS-232 Cable. And, if your computer lacks a serial port for the RS-232 Cable, you will also need our USB to RS-232 Converter Cable (# 18775) to connect to your computer’s USB port.
For more information on connecting to a telescope to perform an upgrade, please install and run MCupdate and click on the Help button.
Hand Control Firmware Updates
Hand control firmware updates can be downloaded and installed using our new HCupdate application.
For assistance with performing a firmware update, simply download and install HCupdate and click on the Help button. Individual firmware versions and change history are available through HCupdate by clicking on the Download via the Web button.
VERSION: 1.1.12
SYSTEM REQUIREMENTS:
- Microsoft Windows® 98SE and newer.
Hand Controls running version 4.00 firmware or later are user upgradable. (This does not include GT series Hand Controls with version 100.0 or later.) The firmware version can be determined by entering the Utilities menu and selecting Version: the top line of the display shows the current hand control firmware version.
Upgradable hand control firmware is available for the following mount types:
- NexStar GPS
- CPC Series
- Special Edition Series
- Advanced-GT
- CGE Series
- GT Series
- SLT Series
Hand Control updates require a PC based computer with either a DB9 serial port or a USB port with a USB to DB9 serial adapter running Microsoft Windows 98SE or newer.
An RS-232 Cable (part #93920) must be made or purchased to connect between the mount and computer.
