Description

10 Subs at 10 minutes - but sadly "only" @ 400 ISO. Should have taken 800 ISO.
This pic really needed (and got) a flat, since I was stretching vignetting otherwise.
This has some brutal processing with Fitswork in it.
tonal correction, then leveling the background while protecting the center, then wavelet filter.
