Firmware Versions on the CGE Pro Series
Non-English Hand Control Owners - read
this. The
information below is for English-version hand controls. |
CGE Pro scopes have two sets of processors. There are processors
in the hand control (HC) and there are processors in the base of the scope
in a section known as the motor control (MC). The MC firmware can be
updated by the owner (read
this).
There have been two versions of hand control available for the CGE Pro:
- Hand control version 4.X. This hand control can be updated by the
owner. Read
this
for step by step instructions on upgrading the firmware.
- The NexStar+ hand control. This hand control can be updated by the
owner and began shipping with new CGE Pro scopes in January 2012. It
is also available for purchase since February 2012. Read
this
for info on this new hand control and

for step by step instructions on upgrading the firmware.
NexStar+ Hand Control
Celestron has posted an official page detailing all firmware versions

Version 4 Hand Control (firmware files are named GEM)
- 4.22 - Fixes the date when the scope is used with a GPS receiver that
returns a date 20 years in the past.
- 4.21 - Fixed bugs related to tandem operation (OTA orientation), Meridian
Mode and land objects.
- 4.20 - Fixed a problem with a runaway slow slew if a GoTo is too near the
meridian flip point. No Response errors now give a "Press UNDO to
continue" option. For mounts with a GPS module in use, changed the
messages displayed to clarify when the GPS was still attempting a link and
when it was successful. Fixed and error when syncing on stars in
southern hemisphere via the RS-232 sync command (for example, from a
planetarium program running on a laptop).
- 4.19 - Adjust communication protocol to assist MCupdate. Added
"Custom Rate 9": the ability to set the maximum slew rate during a GoTo
(requires MC version 6.12 or higher). Fixed an error in the GoTo
RA-Dec menu item. Hand Control now reports immediately if the are
communication ("No Response") difficulties at start up.
- 4.16 - Corrects alignment system errors for use in the Southern
Hemisphere. Fixed error when using SAO stars (selected from the STAR
button) as alignment objects.
- 4.15 - Original version for the CGE Pro Series. This version is
largely unusable in the Southern Hemisphere.
MC Versions
- 6.51 - Improves guiding in Declination: solves problems caused by
mechanical backlash and motor cogging, Smoother and more precise
anti-backlash compensation. Improved tracking. This version may
consume additional power and some people have noticed a different sound from
the motors while slewing.
* One beta tester (of many) observed violent oscillations, if this happens
to you, please report it Celestron and discontinue use.
- 6.17 - Fixed problem with sudden motor deceleration for high values of
"Custom Rate 9". The final GoTo approach is now faster and
quieter. Fixed error in GoTos near celestial equator. Partial fix for
declination guiding error (final fix to come in next version).
- 6.12 - Fixed a backlash correction error. Support for "Custom Rate
9" (introduced in HC version 4.19 - see above). Added new "Aux"
command to support better autoguiding via RS-232 communication via the port
on the bottom of the hand control. Fixed an error that prevented some
user settings from being restored when the scope is powered up.
- 6.09 - Fixed an error which caused RA limits to partially active even when
disabled. Fixed errors which caused GoTos to fail in rare
circumstances. Pauses motors while trained PEC values are stored to
permanent memory. Fixed an error causing bad GoTos after canceling PEC
training or using PECTool.
- 6.07 - Activated user defined RA Limits.
- 6.06 - Original version on the CGE Pro Series.
