In order to better understand the empirical description of the Moon halo we need more deep images of the Moon itself. We have studies of point sources that show the halo but need a connected set of images from one night that allows tracing of the Moon halo out far, and then a set of images of the sky that show the halo but without the Moon in the image. We almost did this for one night but could improve the data in the following way: Image where Moon is in the frame should be deeper which probably means overexposing the CCD or we should get MANY shorter exposures and then stack them. We also need longer exposures from the non-Moon part of the scan to go as far out as possible.
SWARP may be useful for generating one connected picture of the Moon Halo, suitable for study and display in papers.
