Description

Second target yesterday. Great to see what details this camera can produce even with these short exposures

Quote from Eric Solis (which I find a great description of this target):
The Crab Nebula is a very exciting but odd-looking object. I find it fascinating that something so beautiful (and strange) had an incredibly violent birth: the nebula we see today is the remnant of a super nova whose explosion in the year 1054AD was so violent that it suddenly appeared as the brightest object in the sky, so bright it was visible during the day.

B

Complete rework. I was frustrated at the loss of details in my processing so I tried a different approach

C

Decided to work a bit on a closeup. Had some blown out pixel and decided to do it a bit more artistic and use the smudge tool :D Still not very happy with the color, it looks a bit to "candy style"

D

desaturated a bit to get rid of the candy look. still the red is a bit to magenta but with selective colors I get nasty pixel artifacts...
