Hello Karen,

About the photometry of moving targets, is there in AstroImageJ the possibility to fix, independently, the aperture used for the photometry and the one used for the searching of the centroid? This tool can be very useful for fast moving objects, in this case would be possible to use a small aperture for the photometry but a larger one for the centroid issue, allowing the track of the moving object, but doing the photometry using a small an independent aperture. Or may be this is solved in the new versions? Thanks a lot!
