This firmware allows the SynScan V4/V5 hand controller to work as a transceiver between a computer's serial port and a Skywatcher GOTO telescope mount's hand control port. There is this Skywatcher firmware which I may try:. So I don't think it is anything to do with the RS232 to USB connection. When attempting to slew into the dead sector, I can hear the motors react a little, but there is no movement. Since this occurs on both the Linux and Windows laptops, it suggests to me that it may be a Synscan problem, but I can find nothing in the Syscan setup that controls this. The scope is properly balanced, so it is not a question of motors losing lock

Slewing with the HC is not a problem, it does what it is told. Do you think it is a Stellarium or hand controller issue? Updating the Synscan to the latest version: 4.39.10, made no difference. It is not possible to slew to any object on that sector. It seems to be always the Eastern half from roughly North West to South East, regardless of time and RA. I have equatorial selected, and allow auto flipping in the Synscan HC: this occurs in exactly the same way on the Windows laptop and the Linux laptop. I can now slew the scope from Stellarium, however, it will only slew to targets in approximately half of the sky if I try to get it to acquire a target in the problem half of the sky, Stellarium then loses lock, meaning that slewing to a target in the working half of the sky, it points entirely the wrong way. I now have a replacement HC which connects properly to Stellarium. I was having trouble getting a connection to my EQ3/2 Synscan hand controller. I have Stellarium installed on a Windows 10 laptop, also installed on a Linux laptop with Ubuntu19.10 Eoan Ermine. Hand set version 4.15 with firmware v 4.39.10, upgraded from 4.39.04.

I have a Skywatcher EQ3/2 Pro mount with Synscan GOTO.
