Hi Basil,
In the current daily build version of AIJ, I have added an option to specify RA in hours to the "General FITS Header Settings" panel that can be accessed in the DP panel by clicking the "Wrench" tool as shown below. When that panel opens, you should see
the new "Degrees" setting next to the "Target RA Keyword" text box. Enable that option and let me know if it solves your problem properly.
To update to the AIJ daily build, follow the instructions here:

My CCD records the Target RA in decimal degrees (not hours) causing the DPCC module to calculate incorrect altitudes + azimuths (airmass, J2000 positions, etc.) Is there a way to tell DPCC the target RA from the FITS headeris in decimal degrees?
Extract of FITS header:
33 RA 165.7209568 [deg] Telescope pointing RA R
34 DEC 18.66424214 [deg] Telescope pointing DEC R
Log extract from DPCC
Observatory name "Custom Lon, Lat, and Alt entry" manually selected
Target coordinates = 21:43:05.484 +18:39:25.39 (Epoch of Observation) (from FITS header RA and DEC)
JD = 2457871.613519 (mid-exp)
HJD = 2457871.611227 (mid-exp) (correction = -3.2991 minutes)
BJD(TDB) = 2457871.612031 (mid-exp) (correction = -2.1415 minutes)
Altitude = -26.91 (mid-exp)
Azimuth = 28.84 (mid-exp)
Hour Angle = -10.20 (mid-exp)
Zenith Distance = 116.91 (mid-exp)
Airmass = -1.0000 (mid-exp)
Bias corrected with mbias.fits
Dark corrected with mdark.fits and exposure time scaling factor 10.0/10.0=1.0
Flat corrected with mflat.fits
