About this image

Supernova at magnitude 12.7, but enhanced by galaxy background, so is approximate (Measured from Lum image). The star image is saturated in 2 min, so its fairly bright ! Ill use shorter subs next time.
Detail: Gain 100 (21%), T= -10 C. Four darks. Auto guided, but not quite focused (unintentional). Imaged with SharpCap, stacked in DSS, and combined in AstroArt5. Saturation increased.

Looks like M60 could be old stars, whereas 4647 is new blue stars by colour contrast. Is this real?
