Default ASTRO: M-51

I took the liberty of making a tweak or two

you have excellent data: good flats too.

but the blue channel's black point was skewed brighter than the red and
green

there were a few other things regarding the relative strength of blue
relative to red and green was also adjusted

i can't do anything with the cores though and there's only so much I can do
starting with a jpeg.

calibrated FIT stacks of LRGB would be a lot of fun...
