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.
