Steven ★★★★★ Oct 22, 2026

Finally, a simple way to connect my older telescope mount to my laptop without any driver headaches. The compact size is perfect for my mobile setup and it worked on the first try, letting me control the scope with my planetarium software. A solid solution for anyone needing to bridge old serial gea

It's tiny and light so it doesn't weigh down the telescope setup, and it plugged right into my laptop without needing any extra drivers. I paired it with the RS-232 cable and the mount connected on the first try, no fiddling.

Finally, a converter that actually works with my telescope's serial cable without constant driver headaches. The USB connection is solid and recognized immediately on Windows 10.
