I'm new to the astroberry community. I'm looking to do stacking for planetary and some deep sky objects. Any recommendations for software preinstalled on the astroberry o/s installation or anything that I could install that folks have been happy with?

Siril is available on Raspian OS (buster), the OS that Astroberry is based on. You can use the Debian package search to see which packages are available out of the box, by looking for „armhf“ architecture. Then use „sudo apt install <package>“

I was more looking for the names of possible programs that others have had success with using. Installing them would be the easy part.

Rob,
I recommend ASTAP.
I have not tried it on astroberry but it works fine on Raspberry Pi OS, which is what I believe astroberry is using.

For planetary stacking there are no real solution. I've been trying to install PlanetarySystemStacker with no luck (there are some dependencies not available yet on arm or arm64).

For deep sky stacking and some preprocessing and analysis I've been using SiriL. You must download and compile the most recent code on the repo, because the version included on Astroberry is very old. I've been using SiriL for more than a year with good results.

But this will be useful for a quick and dirty stack on the field. The Raspberry Pi doesn't have the needed performance for any serious image processing task.
