Hi everybody.

I'm having a lot of problems using EKOS and external autoguiding in PHD2. If I enable DEC guiding mode as "Auto" I always get a graph like the attached one. At first, it goes well but when a north correction pulse is done, the DEC red line goes down wildly.

Instead of that, if I only change USBs to my Windows laptop and start ASCOM + Cartes du ciel + APT + PHD2, the graph is perfect, as seen on attachment.

This is my equipement:

  • Mount: Skywatcher AZ-GTI + Star Adventurer wedge + serial cable
  • Main tube: Skywatcher Evostar 72ED 420mm + Canon 550D
  • Guiding tube: Svbony SV165 30mm/120mm + ZWO ASI178MC
  • System: Raspberry PI 4 & Astroberry (INDI Library v1.8.6 & KStars v3.4.3 using EQMod driver)

I have a friend with the same problem.

What could be the problem? Bad settings? Driver bug?

Here are PHD2 logs. I think I'm going to test it again tonight and I'll get INDI logs.


Thank you in advance.
