Default ASTRO: M33 LRGB

This is a combination of some RGB data taken using the PL39000C on the
AP155EDF f/7 along with unfiltered luminance from the ML8300 used on the
same telescope, but with no filter

I had some superb seeing on the last night of luminance collection using the
ML8300 and AP155EDF: I was measuring 1.3" stars

unfortunately not all of the data was of such high quality :-(

this may be a bit excessive: I have 90 x 5 minutes of unfiltered luminance
(7.5 hours) along with 3.25 hours of RGB (11x15minutes) for a total of 10
hours 15 minutes

I've been doing tricolor emission line for so long that I have pretty much
had to go up a steep learning curve to do an LRGB.

I have some Red and Green data taken using only the ML8300 but haven't got
enough Blue to substitute it just yet so my color isn't quite as saturated
as I know it can be to make the image a bit more vivid

Initially I thought it had insufficient data in the luminance (looked
grainy) but then I realized I am actually seeing a very high density of
stars through nice optics with a fine image scale!

See how you like it...

Richard,

maybe a bit on the blue side, but otherwise an excellent image.

I plan to shoot new color for it when I get the chance

It looks blue to me as well
