Hi Gary,

There's not enough info here to provide much feedback. Do you see the apertures landing on the stars correctly as the sequence processes? If not, maybe the plate solutions are off on images beyond the first two? If the stars are very faint, the centroiding may not work, but I assume your stars are fairly bright based on other questions from you. Also, make sure you are placing apertures using RA/Dec (in the Multi-aperture setup panel) if your guiding/pointing/tracking were not precise.
