USB to RJ9 Cable for Celestron NexStar Telescope Console Upgrade Cable (Length: 6feet/180cm)

Worked with my Celestron AVX Nexstar + hand controller. Window 11 recognized it without having to install any drivers.

Great cable and yes, it replaces the necessity for a serial cable. If ya know, ya know!

I have had a Celestron Nexstar 8SE since 2017. It has the RJ9 connector on the hand controller and the adapter cables were too expensive fro Celestron. I saw this cable and purchased it. It works great. I connected it to my Windows 10 laptop and it set it up with no issues. I then connected the telescope to the laptop and brought up the Celestron software. It found the telescope right away and I was able to update it for the first time. I am also able to control the telescope with no problems. Very happy with it.

the cable I purchased from you was bad, and made pretty cheap for the cost. I purchased it to connect my laptop to my Celestron - NexStar 90SLT Computerized Telescope, the about this item in Amazon says it is compatible with this telescope. It most defiantly is not. It was connected to my laptop and scope for maybe 15 minutes doing a download. I felt the cord and it was very hot, in which time I stopped the whole process. As you can see per the pictures it ruined Telescope which makes it unable to anything in that port, which is used to connect the laptop. CAN NOT USE THE LAPTOP WITH IT !!! and that was one of the biggest reason i got it!!the Amazon about this product:About this itemFTDI USB to RJ9 (4P4C) Serial Cable, Please double check the port of your device ( like Hand Controller) before placing order.

Worked great after I downloaded the driver. I did have to use it on a Windows 7 PC for some reason my Windows 10 PC did not like it. Therefore the 4 stars.Once connected I was able to update my Celestron Hand Controller.

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!

I bought it thinking I could use it to control my NexStar* mount. Unfortunately, that requires a NexStar+ hand controller. I guess punctuation matters. At least I was able to use it to update my firmware. But I don't know if I want to shell out for a new hand controller.

So simple. Plug one end into the bottom of the hand controller and the USB into the computer. I was able to update the controller firmware with it and can control the go-to mount with a computer using it too. It worked with both a Windows computer and. Raspberry Pi. Note that if your Nexstar hand controller is newer and has the mini USB, you don't need this cable.
