Hi,
Simple guiding works both with live stacking and tacking frames. After first frame has taken the program should enter mount calibration mode. During this calibration mode program gives standard guiding commands to the mount and see how stars move in frame. For me calibration mode takes about one minute or two.

You can set verbose log level (from options menu) and and try again and upload last log here in forum. To open log folder use "Open logs folder" item in Help menu

I will give it a try when it's possible for me again.
One more question: do I have to stop tracking in EKOS when I want to use Simple Guiding in AstraLite?
My workflow is:
1. GoTo and track objects in KStars/EKOS
2. Start LiveStacking in AstraLite

So to connection to IndiServer are open at the same time.
Is this okay?

Yes, tracking is required and must be on

I'm thinking about how PHD2 and AstraLite can work together. The main problem is AstraLite have to inform PHD2 to stop guiding when AstraLite does dithering and to start guiding when dithering is finished. How to do it?

A quick dig into the kstars code (in phd2.cpp) shows that PHD2 exposes a JSON command interface. This is how kstars interacts with it. github.com/KDE/kstars/blob/master/kstars...ternalguide/phd2.cpp

Thanks! TCP + json is no problem for me ))

How works the "Test calibration"?
When I hit the button I see one frame is taken and nothing more happens.
I expected that the mount will be moved in the one or other direction.
Since we have had a cloudy sky for weeks, I tried this indoors with the dust cap on the telescope.

Hi, yes, it moves the mount and calculates stars offset on each move
I see the problem in you screenshot: you mount is parked (and not in tracking state) and can't be moved.
I'll fix the program so that it displays a message that you need to point the mount at the desired part of the sky and turn on tracking if the mount is parked

Hello Denis,

I tried it once more with unparked and tracking.
The behaviour is still the same.
I attached the log file. Perhaps this provides more info.

Thanks for the log file! I will try to investigate

Sorry for delay.
Your telescope coordinates are near Polar Star (RA=3.06238, DEC=89.3684). I think the mount can't correctly reacts to guidance signals from AstraLite in this case. Try to point you telescope far from Polar Star and try calibration again

What happens with the RawFrames when option "Substract master DARK frame:" is enabled?
Will the light frames be stored after the dark frame was substracted or are they still the raw frames?
In other words: when happens substraction in livestacking? In the resulting stacked frame?
