Fabulous image as always, Pete. I wish I had the patience to create a 21 image stack!

Fantastic image.

@Pete_XL
After referring people to this thread when as subject of using the old 200/4 lenses with astrophotography comes up somewhat frequently I am now curious what this would look like if you reprocessed it now.

Hi Andrew, if you say it would be of interest for others I could search for the old data and give it another try. It really might be that APP plus starnet++ and two years more of spent living time in front of the computer might give better results....

I was wondering mostly because the background is black and rather flat and having seen how much you have been able to pull out recently even from old data I thought this might be a good candidate. I've been surprised with what I've managed with astrotracer, a monster of a 400mm lens, and a light pollution filter, in that same area of the sky, and from my horribly light polluted backyard yet getting some of the dark nebulae detail. So given all that I would think that you now could pull a fair amount of data out of the dark even if it is a nosier image.

I'll have a go at it if I still have the data....

Cheers

So I did my best to reprocess the old data with new sotware and more "experience". The stars are more and the field is deeper. But I am not sure if the DSOs are really better now.

Wow Pete!
That is quite a different processing. A lot more blues in the nebulosity.
And a lot less saturation in the reds.
The stars are better too, a bit fainter stars become visible, the colors show better and the brighter stars are deeply blue now.

How did you evaluate the differences?

Kind regards Jetze

Hi Jetze,
The differences are a new better workflow and a higher position on the never ending learning curve. In the past my skills in holding the noise down without affecting the faint Signal and detail too much were not so good. I learned a bit in the past two years.

Glad you like it!

All the best
Pete
