Yes, this is perfectly true for the combination of a special instrument setup and an observer who can (have time and skill to) write the necessary code. But this condition is difficult to meet... This is why I requested general-purpose program. It would not be an easy job, but the current specifications of CCDs and telescopes would be better than automating general-purpose photographic measurements. > Regarding sequences and comparison stars - it took me > another 50 hours to select comparison stars for some 60 > fields.

Yes, the comparison stars need to be re-adujsted even long time after the initial observation. It would be better if the software does not require re-measurement of the original images, but can do re-adjustment on already measured data. PIXY has a disadvantage in this regard.
