Drive Meade ETX70 via Stellarium

[Hadron2023]

Hi, I have installed Stellarium 25.1 on my PC / Windows11 x86-64 and tried zu control my Meade ETX70AT 1. via direct connection via COM4 (using USBtoSerial & cable set #506) using plugin "Meade ETX70 (#494 Autostar #506 CCS)"- embedded driver and also
2. via ASCOM (V7.0.x) "Meade Classic & Autostar 1" driver via COM4.
In both cases a connection could be established and a slew to object can be started with CTRL0, but the target coordinates are transmitted as RA/DEC (not as AltAZ ). While the ETX70 is AltAZ mounted, the resulting slew is totally wrong.
There is also an ASCOM "AZGoto.."- driver (using observation site coordinatates), but Stellarium freezes, when using it.
Does anyone know a solution for this problem (except using an equatorial wedge) ? Any appropriate telescope drivers ?
Thanks a lot

Stellarium only ever sends GOTO(RA, Dec). The only way to "fix" this is more coding, after fully understanding the existing Telescope Control plugin code. Or using an equatorial wedge.

Coding should not be such a problem, needs only converting RA-Dec into Altitude-Azimuth using observation site coordinates Long., Lat. and sideral time and replace Autostar target comands RA :SrHH:MM:SS#, DEC :SdsDDMM# with Alt :SasDDMM#, Az :SzDDD*MM#.
Noone did this before ?
