Yes, but it is better to modify it somehow. Fortunately it is very well commented.

Hi, there is a nice script made by Robert Lancaster: github.com/rlancaste/AstroPi3/blob/master/setupUbuntuSBC.sh
You can run it as it is or study its content, and run only those commands you are interested in.

Also when using pulse guiding instead of ST4, you can get rid of one additional cable, which is (for me) the biggest benefit.

I have also seen that during that SNR drop to 0, also the green lines between stars disappeared for a while, until SNR returns to normal value. I am using multistar guiding.
BTW: The SNR has been calculated around 500, isn't that too much?

I have just seen exactly the same behavior. The calibration was good, after that first run of guiding also. Then I have sleved to another target (on the same pier side) and then every second guide frame has SNR=0.

Hi Tim, if the checkbox is disabled, you are not dithering, it is so simple. And there is one thing that you lose when dithering is enabled: the time, which is dithering consuming. In my case it typically takes 5-15 seconds between two exposures if dithering is enabled.
Alfred: I am not sure about so big setting (7 pixels). It may depend on your resolution. I am using the default 2 pixels and so far it is enough. My resolution is 1,5 arcsec/pixel.
Hy: I agree with Tim about the default ON setting of dithering. Can you please take it as a "feature request"? :) Thank you

Hi Ron, what settings are you using for Initial Step size and Out Step Multiple?
I understand your point, that during the autofocus procedure the set of stars in "full field" is changing. Sometimes happens that small portion of a star ,that is too much out of focus, is identified as a small star, with small HFR. This then can lead to incorrect calculation of average HFR of stars in "full field". At least this happens to me sometimes.
Now I have discovered that I have better results if I use Step size = 200 instead of 300, which I used to have before. It is also good to set the Out Step Multiple setting to be half of number of typical iteration in first focusing run, eg: if the first automatic focus procedure takes 13 iterations (from right to left of the chart), I am setting the Out Step Multiple to 6. So the best focus should be somewhere in the middle of the V-curve.
All of this applies to Iterative algortihm

There is a difference between shorter and longer exposures, I think it has something to do with amplifiers in sensor. The bias is too different for exposure under 1/100s. It seems that the sensor is working in different mode when the exposure is too short.

It would be nice to add another one parameter into automated flat capture routine. Now there is possibility to set target ADU and range, in which the ADU will be. For CMOS cameras (like mine ASI294MC Pro) is better to capture flats with exposures longer than 1 second. In case of sky-flats this means, that I am capturing flats with trial and error techniques. When the sky is still too bright, the exposure time is too short and I cancel the automatic sequence. Then I need to wait until the sky is dim enough to start the sequence with at least 1 second exposure.
So the feature request is to add also a range setting, in which I can set the exposure length, and if the length is (typically) shorter, the sequence is canceled, and re-executed again after some time, lets say after 1 minute.
