Hand Control Version 4 for the NexStar GPS, CPC, SE, SLT, GT and 'i' SeriesClick here for a consolidated User's Guide to all the new features in hand control version 4. Owners of most older scope models can now purchase this hand control - click this for details. In February 2005, Celestron introduced NexStar hand control version 4. First available to the public with NexRemote, version 4 is also available on the new user-upgradeable NexStar hand control. The upgradeable hand control ships as standard equipment on the CPC, SE and SLT. The upgradeable hand control is also available for purchase separately for owners of existing GPS, GT and 'i' Series scopes. This version also shipped with the last of the GT scopes (they have been replaced by the SLT) with these differences - while the GT-compatible version for the upgradeable hand control is 4, the hand control that shipped with the last of the GTs will not be user upgradeable and the version number was 104. At least some of these NexStar GTs with the version 104 hand control have been re-branded as the Celestron StarSeeker - distinctive by its blue-green optical tube - sold through Orion. Note that the GT hand control is compatible with Tasco StarGuide mounts. Some additional notes about the 104/4 version firmware for the GT/StarGuides. This version greatly improves tracking accuracy, keeping objects in the field of view for as long as you care to view them. The tracking is still suited mainly for visual and perhaps web cam imaging as the necessary corrections made by the hand control are significant and don't lend the scope to imaging. Also, this version supports the more advanced serial port control commands. This allows programs like NexRemote and NexStar Control Pad to work with the GT/StarSeeker scopes. The following new alignment methods are available in NexStar hand control version 4.03: Since there is no longer a Quick Align method, if you wish to do some indoors testing follow this guide to perform an Indoor Alignment. The following new features are available in NexStar hand control version 4.03:
Additional new features are added as the firmware is updated, refer to the Firmware Versions section of this web site for details. Also, see the Manuals section of this web site for a version 4 user's guide detailing use of the new features.
