Can I download firmware updates for my NexStar 8i SE-SA?
Since the NexStar 8i and 8i SE do not have PC ports, you must attach the Auxiliary Port Accessory item #93965 to download firmware updates. The Auxiliary Port Accessory has a PC port which allows the user to update motor control firmware downloaded from the internet. This kit includes the Auxiliary Port Accessory and Programming Cable (#93922). You can update the hand control software with the new flash upgradeable hand control that can connect to your computer using an optional RS-232 Cable (#93920). For more information click here.
