Where do I start ?

Again, thanks to everyone for your input and encouragement,
it is truly appreciated.

I had posted an earlier image of Orion and the Running Man nebulae,
and honestly, I was quite pleased with the result, and then....well.....

I posted a tweaked version.

To be honest, Orion isn't my favorite object in the sky,
but, know what ?

I have grown to embrace it over the days.

Short story, I took several sequences on the night, same camera and scope, but different filters, ISO and exposure times.

Something I didn't think of at the time was.....
camera orientation.

I removed the camera several times from the scope to change the filter.

Yes......I have a filter draw.......

I changed from a Optolong clip in CLS to a 2 inch IDAS LPS2 filter,
and also Cameras.

In doing so, I unknowingly rotated the DSLR 180 degrees.

That said................

I revisited to the sequence I took and decided to stack them.

Thanks again Martin, and Robert.

40 x subs and this time....I created a dark sequence.

The process was simple yet gave so much.

I have so much to say, but will keep this short for now.

Image details as follows:

Sky watcher 80x400mm refractor
Canon 1100D DSLR modded
IDAS LPS2 filter
Skywatcher StarAdventurer
40 x 45 second subs
ISO 1600

Stacked in Deep Sky Stacker.

Processed in Windows live Photo Gallery.

No cropping. ( yep there`s artifacts )

Comments welcomed.

Thanks again everyone.

Oh and .......

I`m still happy !!!

Paul.

You've created something very unique Paul.

Reminds me of a water colour painting

I love it!

Thanks Peter,

I am becoming very aware of the fine line between
science and art when processing an image.

The other thing I am noticing is the difference in
screen resolutions when viewing and processing images.

I would imagine using automated prepossessing programs
would produce the same final data image irregardless of the
computer being used, but the image would take on a varied
visual result depending on the screen resolution and settings ?

I have noticed on sites that post black and white images, the use
of a grey scale for screen calibration. I don`t know if there is a similar
test pattern for colour ?

That said, I do look at images in various screens to gauge how
things are looking.

I take the term `very unique` as a huge compliment !

Thanks again.

Paul.
