I managed to image ISON every morning again this week.
I think the nicest is ISON Mars, dwarf galaxy Leo1 and Regulus. This is a combination of (15) 6 min exposures where a median combined ISON aligned image was composited with a median combined star aligned image. The non background uniformity to the right "south" is from Zodiacal light, I think it adds to the image so I left it in. The 4.5" F/4 astrograph and a Sloan yellow filter were used...
