This was a quickie while I waited for M17 to drift into my sights tonight.
LRGB unbinned (L=7x200s, R=3x180s, G=3x200s, B=3x220s) for a total of about 53 mins data.
I'm embarassed to say I set it up to run without turning on cooling, noise is at 11 degrees, not usual -25
Still, leaves earlier attempts in years gone by with the 450 in the dust. Only stretches and colour saturation and a bit of shadows/highlights in PS at the end. Haven't bothered trying to sharpen or use the 100sec L subs I took. Pretty happy how its been guiding tonight too.
Bit bigger version available

Sure beats gazing at this one wistfully for a long periods in the old Tasco 4.5" reflector too, trying to figure just how far in I could resolve
