Updating local copy of astrometry.net

[Astro Keith]

I've been struggling with compatibility issues on my Raspberry Pi builds.

Bookworm OS seems to be best avoided for now. Too many issues. However will be needed eventually for the new Pi5 hardware.

Beware of the latest numpy, ver 1.26. It's not backwards compatible. v1.24.0 seems good.

I want to update the astrometry.net version (currently I'm on 0.90 ) on my Pi. Is there a straightforward way. (I installed using sudo make, sudo make py, sudo make extra, sudo make install)

TIA Keith

Hi,

If you're getting errors compiling the astrometry.net code, please go ahead and post them.  As far as I know, it should build fine on any typical Linux machine.  I just tested Ubuntu 23.10 and numpy 1.26.1 and it worked.

cheers,

dustin

oh, and to your question, there isn't an 'uninstall' command, so to upgrade you can just `make install` over top of the existing version.

[Astro Keith]

Thanks Dustin.

I've been using 0.90 so far. Great.

I updated to 0.94 last night. Works, except for one thing. Previously I was using the fact that in the solve result any bright stars in the field would be listed. In 0.94 this seems to have gone. I went back to 0.90 and it reappeared.

So can I get the equivalent result in 0.94?

What I am doing is during telescope to finder camera alignment calibration, the main scope is pointed accurately at a bright star, and then the next solve reports the name of the brightest star found and its offset is saved for future reports of scope RA & Dec.

TIA

Hi Keith,

I looked through the source code but I don't see any changes between 0.90 and 0.94 that would result in different sets of objects being labelled.  Are you building from source or using Debian packages?

If you can send an example image or xylist, that might help track this down.

cheers,

dustin

Hi all,

I don't get my local raspberry pi 5 with bookworm 32bit to solve an image, even though nova can[0].

Is there something else still "to be avoided" with the current raspbian and astrometry.net?

[0] https://nova.astrometry.net/user_images/9941687#annotated

I got astrometry.net to run well on my pi 4 and previous raspbian versions. I installed astrometry and the 4100er indices as before but it cannot make it solve the linked image [0] and also other images I know to be solvable within seconds from the previous raspbians.

solve-field --version says 0.93

I do not see any errors when it is running through all the indices. It just does not find a solution and finishes.

Maybe I miss something obvious and you can help :).

Best regards,

Andreas

What's the full solve-field command-line arg you are using, and what are the full logs it prints out?

You probably want  "--downsample 2", that's what the web service does.

Hi Andreas,

I'm now running astrometry.net on a Pi5 64 bit Bookworm/Debian 12 with no problems. It's about x3 faster than the Pi4.

I found that I had to install libnetpbm11-dev instead of libnetpbm10-dev

Some of the dependencies (pip ones)  had to be install in a the virtual environment , others (apt-get) not.

Hi Dustin,

I used this cmd before and it did not work...

solve-field -u degw --crpix-center --tag-all --overwrite Stacked_screenshot_05.05.2024_2.png

When I use the --downsample 2 then it works. It gets a Ra/Dec solution, but it does not solve it. There is no final print of the solution and the .solution file is not stored, which it does both with other images.

What interests me is why the nova solution tells me it solved it. Does this mean as long as there is a .wcs stored, even though it misses the .solution file, nova says it was solved?

When checking nova, it does stop sooner. My run tries longer with more field objects being tested.

Best regards, Andreas

Hi,

If you have an old .wcs file in the current directory, it will print the results from that file even if it doesn't find a solution.

I think you mean .solved, not .solution ...

Can you please send the link to the nova.astrometry.net submission?

cheers,

dustin
