Eagle Nebula new and improved

I wasn't 100% happy with my RGB version so I went back and completely reprocessed (you knew I would ).

This was composed from 70min SII, 105min Ha and 80 min OIII with just 6min each for RG&B

The new version has (I hope)

1) Better more natural colour balance
2) Tightened and improved star quality
3) Better star colour
3) Reduced harshness around the pillars with more clarity while maintaing respect for the light
4) Reduced noise

This last outcome (4) was a tough ask with only 3 X 2min each of RGB but never the less very minimal noise reduction was used, instead I used the smoothness of the good NB signal to maximum advantage through special blend techniques.

The Eagle Nebula full frame @ 50%

Main Nebula Crop @ 70%

And although the seeing was very ordinary....here are The Pillars of Creation @ 100%

Nice repro Mike!, I missed the original one, however it seems the latter an improvement. I like in particular you reduced a bit the blue/magenta dominance that was quite evident in old version.

Overall a stunning M16
I have also the data to process mine but I will never get closer yours in terms of resolution

Clear skies

Cheers Marco, glad you liked it

The blue magenta is real...the intensity might be debatable (how to determine that, I don't know) but it is certainly there

I am sure your M16 will be a corker, look forward to it

Mike

That's a top photo now - it's much better.
It seems that all your work has paid off.
Its' always worth another go at reprocessing.
Every pic is different & it's almost as though
you have to learn how to process each picture.

Totally agree, over the years I have failed to get it right first go on quite a few occasions (impatient? ), my Deep Centaurus A is a perfect example, this took many repro's over a few months to finally nail and the final result has now been featured all over the World and been looked at many thousands of times at my web site since....perseverance pays off, never give up I say and don't be so proud as to not let us see the progress along the way , makes this forum fun

Yeah you got that just right.

That's the best version. Remarkable for such short hours in RGB.

Greg.

No doubt about it, definitely an improvement Mike. But as you say suffering from a lack of RGB data.

Cheers, Marcus

Thanks for looking men and nice to here I did actually manage to improve it and it's not just me going batty

Working wiith just a few minutes of RGB was certainly a challenge, lucky it was with a 12" at F3.8.

wow mike you are certainly full of surprises excellent result with the data you have. are you going to get some more rgb in the future to reduce the noise?

Hey thanks Dave more RGB..?...hmmm, ya know, if I had an observatory then probably yes but without I will most likely just want to move on to something new next session

Thanks Ross, not 100% ideal data but I was happy with the overall result in the end (after several tries )

Yep great effort, no data has gone to waste its all there from the faintest to the brightest.

I still love how those stars are so sharp and round right to the edges. It would be devastating under a very dark sky with many hours of exposure. Think of all those extreemly low surface brightness tidal streams around galaxies waiting to be captured
