Celestron recommends that you always use the latest version of the firmware in your devices. Firmware updates can deal with bug fixes or see the addition of a new feature(s).
However, did you know that Celestron has a page specially dedicated to firmware updates for its range of computerised mounts and a wide range of accessories, such as SkyPortal and StarSense? Having all these on one page makes looking for the update for your device easier. The page is for devices whose firmware can be updated using Celestron’s Firmware Manager (CFM) software which can be downloaded here.
On the page you can easily see the products that firmware versions are available for, their release date and history, firmware versions and any notes relating to the update(s) too.
What is also very helpful is that you can be notified of any updates by email too when they become available.
The firmware update page can found here, and you can submit your email address for notification of updates by clicking on the orange “Notify me of updates” button on the page.
