ASTRO: M33 Normal LRGB view

Leaving out the one 30 minute H-alpha frame really changes things. Even
the color balance changes. Yet it wasn't used for color, just the L
image. I don't get how that works. I see Gendler has a page on LRGB
imaging that shows the same effect for the Running Man Nebula when using
HA (all HA in his case) for the L frame. It goes from blue in LRGB to
red in HaRGB. Weird.

I increased contrast of the core to bring out the dust lanes and that
motor oil color seemed to show up again. Before I did that it was
mostly blue. Another odd change I don't understand.

Mighty image Rick. The Ha version is also a good effect. I once did
something similar for M101.
