M42 Short exposure alt/az.

Messier 42 or NGC 1976.

This image of the Great Orion Nebula was taken on Saturday evening the 29th September 2017.

It has taken me a while to post as processing was a real pain. You can process this one so many ways that finding the right balance is tough!
I am sure I will still abuse this data for some time, hoping to squeeze out a few more drops and improve on the star quality and colours. Keeping the core tamed and getting the finer outlaying detail is a fine balancing act.
Then there is noise,light pollution and gradients to contend with.

At any rate I have settled on this image to share here with you the reader.
The details of my little photo-shoot on the night are as follows:

Skywatcher 102 F5 mounted on a alt/az goto.
Canon 1200D DSLR with no modifications.
Meade Nebular filter.
ISO 1600
60 X 30 second light frames.
60 X 30 second dark frames.
60 X light frames in AV mode.
All stacked in DeepSky Stacker and processed with both Star tools and Photoshop.

With the processing on this image I tried to use PS more extensively and get to grips with processing DSO with it.
PS and Star tools work well together and the more I learn about PS the more I like it, used in combination they will produce better images together as my skills with each improves.

For those of you not too familiar with the night skies here is a image taken from the planetarium freeware, Stellerium.
It shows where the constellation of Orion is and the red arrow points to M42 in the small green block.
For those in the Northern hemisphere you may notice that Orion appears "upside down" from your perspective. This is the way we see it in the Southern hemisphere.





And here is my rendition of this fine nebula.



Many thanks for reading and looking.
