Celestron NexStar Evolution 6

Worth knowing before you buy

How do I update the firmware on my Evolution mount?

You need to connect the hand controller to your Windows PC using either a USB-to-serial adapter (older HC models) or a mini-USB cable (newer NexStar+ HC), install the PL2303 driver, install Java, and run Celestron Firmware Manager. Multiple users report this process is confusing and poorly documented by Celestron, but following the detailed step-by-step procedure in the firmware update thread works reliably.

Can I update my Evolution firmware wirelessly using WiFi?

WiFi firmware updates are possible but less reliable than USB connections. You need SkyQ Link, both StarSense camera and HC plugged into the mount, your computer connected to the mount's WiFi network, and both camera and HC connected to the computer via USB.

What CFM (Celestron Firmware Manager) version should I use?

Version 2.1.

Do I need both USB cables connected to update the StarSense camera firmware?

Yes—you must connect the StarSense camera directly to your PC via a mini-USB cable in addition to connecting the HC to the PC. If you only connect the HC, CFM will falsely report that the camera has been updated when it has not.

What should I do if my hand controller won't update or gets stuck in bootloader mode?

Try pressing MENU and OPTIONS (Celestron Logo) simultaneously to force bootloader mode, then retry the update with CFM. If that fails, try reverting to an older CFM version like 2.

Does the Evolution mount come with the latest firmware from the factory?

No—even new Evolution mounts ship with outdated firmware that may be a year or more old. Users report receiving mounts with firmware versions significantly behind the latest available, so checking and updating is recommended, especially if you encounter GoTo accuracy issues or plan to use StarSense.
