The all night pain is really not necessary. Once you get the rig going, just let it go and go to bed
. Automation is not reallY required. Stay on one object and just have the capture prog change filters (if required) by itself . So what if it's still taking some dud subs due to clouds , dawn etc. just stop it when you get up. That's how I do it, and have for years.
If rain is a worry, invest in a rain sensor and have it alarm and wake you up when is very cloudy or raining for a quick coverup.
