It's wicked cool. Review: Works with old Nexstar Hand controller - install the FTDI drivers - Initially I could not get it to work with my old Nexstar handcontroller (with the RJ9 jack), and I was about to buy the (5x more expensive) Celestron wifi dongle instead and send this cable return... But - after carefully reading the instructions from the vendor; turns out you need to download and install the drivers for the FTDI chip (link above). The ftdi website provides a setup file that you can just run and it automatically installs the drivers. After that windows recognizes your mount (you head the bleep when you plug in your usb cable). With that I can now control my mount with the free Celestron software (and later Sharpcap and NINA). Turning my junkyard Nexstar 127 SLT (with a planetary camera) into a great outreach telescope! Review: Worked perfectly! - Worked perfectly to update my Celestron Evolution mount with a MacBook Pro with M1 Pro using a USB A to C adapter. Just follow Celestron webpage instructions. ## Features - FTDI USB to RJ9 (4P4C) Serial Cable, Please double check the port of your device ( like Hand Controller) before placing order.
