Add settle down time after auto guiding start or resume

Currently Ekos supports setting settle time in align module, but there's no similar setting in guide module.

After guiding is started or resumed from dithering, it is better to wait several seconds before capturing the next light frame. So I hope that there is an option for this purpose in guide module: a settle down time setting. When settle down time is greater than 0 s, a delay should be added before capturing the next light frame after guiding is started or resumed from dithering.

Though I can set a delay in capture module, I think adding settle down time setting in guide module will make things more clear.

This is in the Guide options under "Dither"

It probably depends on the setup and would require testing but how many seconds would you typically recommend for the settle down time?

I noticed that this settle time is the delay after dithering and before guide resuming. My expectation is the delay after guide resuming. I am not very sure that settle time is the delay after guide resuming.

I usually settle for 5s after dithering and 15s after guide resuming to ensure the mount is stable enough. The settle time under "Dither" seems to be the delay between the dither and guide resuming, so that's why I said I add delay in capture module between each frame because this delay performs after resuming.

That's exactly my impression when using ditherring. I had hoped settle time was the time between re-starting guiding and taking the next picture but it doesn't look like it. I might be wrong though.

Hello,

I have the same issue: when Autofocus is pausing the guiding, then starting it again, the next image is captured without any delay.
After Autofocus, the star can have drifted a lot, and we need to wait a bit before capturing.

Thanks.
Regards,
Florian

We have the same discussion here indilib.org/forum/ekos/3466-lost-star-wh....html?start=48#27333 but I think no changes have been made yet. Unfortunately I am not in a position to make changes to the code myself.

Hi everyone
I find the pause after dither in the guide module works fine with the internal guider. With PHD2, I add a wait to the capture instead. I think that amounts to the same thing (?).

The pause is after dither but before guiding is resumed. That's why it fails to bring guiding into a stable state before the next picture is taken.

I was wondering why I was getting a blurred image after dithering, even though I had a 10 second delay set.
I noticed this weekend that as soon as the guiding resumed, the shutter opened. I need a delay between guiding and shutter control.
