Thanks Kevin, will check tomorrow (have my mount indoors, it's raining here too), although do not have high hopes for the driver level control of the goto slew rate.
Btw. I've checked the Celestron CPWI User Manual and there the user can change the goto slew rate:

Custom Rate 9
Your telescope slews to objects selected for GoTo at motor speed Rate 9. Lower the Rate to conserve battery life if you are using an external power source. Raise the Rate to slew to objects as quickly as possible.


The comms syntax for GOTO commands looks identical to the one of SkyWatcher but I cannot find the goto slew rate set function like the above-one in CPWI :o(

Hi Kevin,

I've recompiled skywatcher.cpp with the suggested changes but see/hear no change in the speed of the goto/park movement - any other ideas?

Hi Kevin,
my mount has firmware 3.14.23 - there has been few updates since then, and one of them says:

Version 3.23
1. Fixed a bug with the SET_SPEED extended command.


Can this be the cause for my mount ignoring the speed setting?
Do you recommend an upgrade?

Thanks,
Mariusz

Hello,

so, to answer my own question: I've upgraded to 3.23 but it changed nothing concerning the use case.
Hope, Kevin will get some clear weather to try the code change suggestions - the weather is getting better here :)

Cheers,
Mariusz

I'm traveling for the next week, so it will be a while before I can test.
