NGC 55 Sting of Pearls with DSLR and RC6

Around 5.5 hours of 3 minute exposures with darks, flats and bias stacked in DSS, processed in Startools.

Bit noisy but I guess that's a limitation of using a DSLR.

Looking at the histogram in Astrophotography Tool, all the channels are way to the left, with the red channel being clipped a bit. I suspect that's to do with the long focal length of this scope and using an unmodded DSLR?

I'm happy with the result.

thanks for looking

Mark
