Step 3, I got an unrecognized command error when I tried the final line, did you mean for me to use "#add_path" in both instances? I did that after the error, hope that was ok. In case it isn't already obvious I'm a unix noob. Does #add_path make one directory automatically point to another? I see too that at least for now (I haven't launched Ekos yet) I have two copies of all the index files, ~640MB of data; once I confirm all is well can I delete the copies from their original directory in /usr/share/astrometry - will it let me..?


I was not precise in step #3 - add_path are lines in /etc/astrometry.cfg file - you should edit the file by running "sudo nano /etc/astrometry.cfg"
After opening the file add # to existing add_path line and add a new one with your new path. Write with ctrl+o and exit with ctrl+x. You're done

The solution is to change location of index files to your home folder e.g. ~/astrometry (/home/username/astrometry):
1. Create the folder

cd
mkdir astrometry
2. Copy index files it
cp /usr/share/astrometry/* ~/astrometry/
3. Change astrometry config
#add_path /usr/share/astrometry
add_path /home/username/astrometry

Well , it does store all the configuration on the raspberry - in /home/astroberry/.indi (INDI drivers) and /home/astroberry/.local/share/kstars (KStars) but only if you connect to Astroberry as a remote desktop (over VNC or via web browser).
If you start KStars from your PC/Mac INDI drivers configuration is on raspberry (as above) but KStars configuration (and Ekos profile) is saven on your PC/Mac.

You can reconfigure as already discussed OR use Local Scaling option available in Settings menu in the sliding panel.
This option is available only when Astroberry is accessed with a web browser. It will rescale 1920x1080 to your screen resolution, whatever it is.

So it looks like 5GHz wifi on RPi 3B+ is real pain in the neck :-/

I think you're absolutely right. In this view it's not even an image of even horizon, but particles sliding on it.
There's quite nice explanation of the topic in this video.

Is even horizon part of a black hole? I think it is, as it is specific to this object, also as Schwarzschild's solution to Einstein's field equations.

This actually true. It's like imaging silhouette of a man in a backlight. Still it is a picture of a man ;-)
