Remote Astrometry #54124
Hoping someone can point me in the right direction to use remote astrometry.

The online version works fine. I installed the astrometry driver on my RPI/INDIserver. I downloaded the index FITS files. I moved them to /usr/share/astrometry/. I've added the Asrometry aux driver in my equipment profile. Capture and solve and "solver failed." I don't find the logs to be particularly informative:

Any insight would be appreciated.
Thanks.

"Remote" I believe is if you set up an Astrometry server on, say, a computer elsewhere on your home network with more space and/or processing power than what you're using at the mount and point your controlling Ekos installation to that server.

As you've got an RPi and have downloaded the index FITS to it, you just need to select "Offline" on the Align tab. You don't need the Astrometry Aux device at all; that would be for the case above.

I don't see an offline option. Only remote or online.

Have you got the program 'astrometry.net' installed, as per below? Your initial post says you installed the driver but I don't know if by that you mean what is below or something else.

I believe I did:
sudo apt-get install astrometry.net
per this: indilib.org/about/ekos/alignment-module.html
I did not do:
sudo apt-get install kstars-bleeding astrometry.net

Is there a way to check that I installed the program correctly?

Can check on both astrometry.net and kstars-bleeding with the 'apt-cache policy':

astroberry@astroberry:~ $ apt-cache policy astrometry.net
astrometry.net:
Installed: 0.76+dfsg-3+b1
Candidate: 0.76+dfsg-3+b1
Version table:
*** 0.76+dfsg-3+b1 500
500 raspbian.raspberrypi.org/raspbian buster/main armhf Packages
100 /var/lib/dpkg/status

astroberry@astroberry:~ $ apt-cache policy kstars-bleeding
kstars-bleeding:
Installed: 6:3.4.0
Candidate: 6:3.4.2
Version table:
6:3.4.2 500
500 www.astroberry.io/repo buster/main armhf Packages

Let's also take a look at the permissions of the astrometry files themselves:

astroberry@astroberry:~ $ ls -lh /usr/share/astrometry/
total 9.7G
-rw-r--r-- 1 nobody nogroup 101M Dec 7 2014 index-4202-00.fits
-rw-r--r-- 1 nobody nogroup 104M Dec 7 2014 index-4202-01.fits
... etc ...

astrometry looks good:
Installed: 0.67+dfsg-1

kstars-bleeding (presumably this is the issue?
Installed: (none)

permissions:
total 2.3G

-rw-r--r-- 1 vince vince 179M Dec 7 2014 index-4201-00.fits
etc..

You must have Kstars from the OS's repository installed? It's possible that version isn't recent enough to support offline astrometry plate solving.

So yes, best get the Kstars from the ppa in the links previously.

To help in daylight and without need of attaching mounts and such, you can create an additional Ekos profile. I call mine "Simulators" and I add a bunch of things like
Telescope Simulator for the mount
CCD Simulator for the imaging camera
Guide Simulator for the guide camera
That allows you to do a certain amount of "playing around".

Thanks for your help! I installed kstars-bleeding. Will test tonight and report back.

Yeah... so still doesn't work. Let's go over my setup real quick:

INDI server running on RPi3. Now includes the astrometry driver which i confirmed is running.
I've confirmed that the astrometry program is installed as is Kstars (but I haven't done anything with them... should I be launching Kstars on the pi?)
Kstars/EKOS client is a Windows 10 machine.
The equipment profile has Astrometry as an Aux driver.
We've confirmed the index files are where they are supposed to be and permissions are ok.
I get the same behavior: it captures a picture, sends it to the solver and then solver fails.

What else can I try?

On Windows, Offline is not available, so you have to select remote and select Astrometry driver in your equipment profile.
