Good stuff, Ray, this is just the sort of ultra-faint material that I love to see!
As mentioned in my other recent N3621 post, there is a commonly used name for very-very extended Extremely Faint Disks which are much more prominently seen in the ultraviolet regime :
"XUV" disks
(short for extended ultraviolet)
cheers,Robert
Just to confuse the issue, some galaxies with outer extremely faint and extremely extended Outer disks, are also known in the professional literature as Low Surface Brightness Galaxies !!
(e.g. NGC 289)
