3 years ago Thanks for this bug report.
Turns out, this was solved in https://github.com/dstndstn/astrometry.net/issues/174
BUT, a couple of releases ago I renamed the 'blind' directory to 'solver', and Nova was still pointing to the old executable!
Should be fixed now. (You'll have to resubmit images to get them re-run though.)

If in nova.astrometry.net the advanced option CRPIX in "center" is used, a wrong angle is reported and the new-image.fits contains a wrong solution:

As comparison ASTAP solution: CRVAL1 = 2.980104696514E+002 / RA of reference point
CRVAL2 = 7.314186520962E+001 / DEC of reference point CRPIX1 = 3.690500000000E+003 / X reference pixel
CRPIX2 = 2.454500000000E+003 / Y reference pixel
CROTA1 = 4.978703101753E-001 / Image twist of X axis (deg)
CROTA2 = 4.937158410148E-001 / Image twist of Y axis (deg)
