NGC 6188 in Ara - Mark II

This is my second attempt at this beautiful object, and, I'm still not happy with it, but, it is a marked improvement from the first attempt several years ago. I finished capturing this as the sky started to turn blue at dawn.

I will re-attempt this with the STL-11000M during winter when it will be at a good point in the sky in the middle of the night.

NGC 6188 is a diffuse/emission nebula.

North is left.

This composite consists of one set of images; one set of 19 images taken at ISO-800.
Each individual image was a 300 second exposure.
IRIS was used to calibrate each image (dark subtraction [median combined master dark] and flat field division [median combined master flat {lights and darks}]), to register, align, stack, and stretch.
Photoshop CS4 was used to adjust levels, curves, saturation, colour balance, local contrast, miscellaneous editing, frame and resize the final composite.
