Well here it is, M27 The Dumbbell Nebula in LHaGB with my new ZWO ASI183mmPro. 3/4 of it was taken with incorrect MPCC spacing, the green and blue filters are actually visual filters double stacked with a UV/IR cut filter cos I don't have the proper ones.

Details: Luminance was taken with a Baader Semi-Apo filter. 134 x 30 seconds unguided.
Ha (30nm) 122 x 30 seconds unguided.
G = 110x30 seconds unguided (Hoya X1 Green + Baader UV/IR cut)
B = 79 x 30 seconds unguided (GSO 80A + UV/IR cut double stack)

Total = 445 x 30 seconds of "lucky imaging" unguided on a HEQ5 Pro all Bin2 -10C. GSO 10" F4

There. That should leave you all scratching your heads for a while!

Great effort. Is the camera you are using cooled. Some of the uncooled versions have very low noise.

Cheers

Thanks Mike. I do like the colour of this one. Must be the good filters. :)

Feeling tired a lot lately. My blood pressure has been low since the stents so it's a bit of a struggle to do anything.



Thanks Tim!



Yeah getting there Dunk. I took time off guiding for this shot. I'll attempt that black art tonight, clouds permitting.

Thanks Paul. Getting there slowly. It's great to have no more angina pain.



Thanks Simon! I'll be at it ever clear night if I can.



Thanks M&T! Have the filter wheel now so all I need is the filters.
