I mean the EQDirect cable shows up as a serial port device to the Raspberry, probably named /dev/ttyUSB0 if you don't have other devices connected. By default the driver doesn't know which port to use and doesn't connect automatically, so they need to be controlled by the client application, for example KStars. Connecting the cable to hand controller port is normal for EQDirect cable. So after you connect the cable to Raspberry and start indiserver -v indi_eqmod_telescope, connect to the indiserver from KStars (possibly from other machine via TCP or locally) and open INDI control panel tab. There select EQMod mount and go to connection tab, scan for system ports and select the correct one (probaly only one shows up). This should look something like this:



I have multiple serial port devices connected and they show up in random order each reboot so I have configured a link to the correct port to be as /dev/mount, but you don't need that unless there are multiple serial port devices connected. Then go to main control tab and select Connect. That initiates the actual connection to the mount and then you can control the mount normally.



KStars can also be set up to automatically connect devices when connecting to the INDI server and that can be used after the configurations have been finalized. Don't forget to save the configuration in INDI control panel too.

Snooping is a term used in INDI for getting information from other devices in the system. In this case the mount driver can utilitize time and location information from a GPS driver and as you probably don't have any specified, it uses the simulators by default. That doesn't actually do anything unless you start changing location or time in the simulator so it's harmless, nothing to do with controlling the mount as such. For EQDirect cable you should use EQMod driver, Synscan driver is use to drive the mount via the hand controller serial port in non-PC direct mode. In both cases you need to select the serial port and connect to it from a client application like KStars before there is any more output from the driver.

The power connector of HEQ5 is a bit flimsy, had all sorts of weird serial issues especially when it was cold until I replaced the stock connector with a screwed one.

The command set is documented in the SX wheel manual (www.sxccd.com/wp-content/uploads/2020/11...ard-Filter-Wheel.pdf), but it only has commands to get number of filters, get current filter and selecting new filter with no option for one-way motion.

I use Gemini SnapCap with flat light in my remote observatory, though I'm not sure if it's any cheaper than those options.

As said in some other thread, having just a little bit loose power connector which is quite typical to HEQ5 and others causes this sort of serial errors too so that is also something to test. And making sure the voltage the mount receives it high enough, more than 12V seems to work better, I ran mine at 13.8V.

Good to hear that helped, yes the regular barrel connector is not a very good choice for powering a device that is constantly moving. Also there seems to be some tolerances that some cables fit better than others and thus might work better. Skywatcher has better connectors in some of the higher end mounts like EQ8, but I guess there is a cent or two to be saved by not using those in the cheaper models...

Yes, 3.5.7 should be out pretty soon.

Yes, thought the limits set to the controller would prevent that, but it doesn't seem to quite work... Unfortunately my USB_FocusV3 controller stopped working a bit over year ago so can't test that anymore. It would show up normally, but just didn't respond to any commands anymore.

JPL changed the APIs for retrieving the orbital elements sometime around 3.5.6 was released and fixes are in GIT, to be released with 3.5.7. More info in merge requests invent.kde.org/education/kstars/-/merge_requests/452 and invent.kde.org/education/kstars/-/merge_requests/468
