Hello.

I'm trying to do astrometric calibration in my images. I need to obtain the astrometric solution and compare with a reference catalog, for example 2MASS. The separation between my calibrated stars and the catalog should not be higher than 1 arcsec.

For that I have tried Astrometry.net, Sextractor and Scamp. 70% of my stars have a separation less than 1''.

Do you know other softwares/methodologies to do some astrometric calibration?

Cheers,

Cédric Pereira
