Is ASTAP ready for seamless integration in EKOS? #47082
I would hazard a guess that your system is actually an arm64 system rather than amd, so try an intstaller based on ARM. I have it running on an Odroid without problems, using astap_arm64.deb.

120 MM Skywatcher Esprit on Celestron CGEM DX HC: GEM 5.29.7137 MC: 6.50 6.50,
ZWO ASI 224MC or QHY-5L-II-M for guiding,
Nikon Z7 8256 x 5504, 35.9 x 23.9mm 4.34 um pixel size.
1) StellarMate on RPI4
2) Kstars on Odroid-N2 on Ubuntu-mate 20.04 and
3) KStars on Astroberry on RPI3.

As Jerry said the NanoPC T4 is an arm computer so:

program, 64 bit arm version:
sourceforge.net/projects/astap-program/f...p_arm64.deb/download

if that doesn't work the 32 bit arm version:
sourceforge.net/projects/astap-program/f...p_armhf.deb/download

plus the universal star database probably already downloaded.

Is ASTAP ready for seamless integration in EKOS? #52167
On macOS the app ASTAP solves fits files extremely rapidly.
However I can't succeed solving the same files with KStars using the ASTAP solver option (it works very well using the Astro.net solver option)
ERROR : 2020-04-19T17:47:27 Solver failed. Try again.
What am I missing ?

Can you provide to me both the image and the .ini file from the temporary directory for investigation? In the .ini file, I can see the command used and compare whats required to solve the image.

Han

The generic checklist is as follows:

At least 30 stars are visible.
Reasonable round stars.
Image dimensions at least 1280x960 pixels.
An approximate position for a spiral search is specified correctly. (unless you do a 180 degrees search)
Image is not stretched or heavily photo-shopped.
Correct image height in degrees specified within 5% accuracy. (Check focal length, sensor size settings or try FOV=auto once)

Hi Han,
In the Solver panel I clicked on "Load & Slew..." and selected a .fits of M 106

That looks all good except that it is reaching the mag 17 limit of the database. It can just solve your image. You better install the G18 up to magnitude 18 database. For detecting the smallest star pattern, the database should go equal or go deeper then your image. Your image contains stars at least up to magnitude 17.8.

The G18 you can download from Sourceforge at:
sourceforge.net/projects/astap-program/files/star_databases/

There is only a ZIP file. You should extract it and move the .290 files to /opt/astap The database is selectable in ASTAP, but it's probably easier to just delete the G17 files. It will find the G18 automatically.

Cheers, Han

p.s could you report back about the performance of ASTAP? I have no experience with images created with long focal length like yours. I'm only working with a short focal length telescope.

I work at 1320mm focal length with an old sony h9 based camera, so quite narrow fov. And I most say that ASTAP works very well! Only if the scope is way off, I find that astrometry.net (online) is more stable. But in 95% of my usage, ASTAP works fine and is much much faster than astrometry.net. So thanks for this and well done :-)

Hi Han

I downloaded the G18 package and copied the 280 g18 files in the database /opt/astap.
I deleted the older v17 files.
The ASTAP.app works well on both sets v17 and g18
However this didn't improve the situation with the KStars/ASTAP solver : "2020-04-20T09:59:10 Solver failed. Try again."

I don't think that upgrading from v17 to g18 is the explanation of the failure in KStars because ASTAP.app works with v17.

Let's further investigate. For the image which fails, could provide me with two files from the the following path

\tmp

The image with a name similar like: fitsZ13964.fits
The astap report file: solution.ini
