Hello all, I am interested in how one can generate an astronomical map based on Right Ascension (RA) and Declination (Dec), without converting RA to degrees and reversing (-15 * RA).
There is the affine transform tool which can be used to scale X and flip, but this then generates the 0-360 degree scale. The main issue is that the IAU standard is for the RA to start at 24 and run east to 0! Any ideas would be most welcome. Lester
