48 hours on a 40 million pixel CCD

EDIT: Repro, see message 14

Tada! Now that I got your attention can reveal that I didn't win the lottery nor sold out a kidney, it is just a 4 panels mosaic with my trusty 16803, measuring more than 6350 pixels per side
Pay attention that the largest resolution may take a while to load, however it is worthing the wait to appreciate the smaller details on the subject.

I feel a bit ashamed to mention the subject, so I will instead let you discover it on the link below:

http://www.glitteringlights.com/Images/deepsky/13667287_7Mtr58#!i=1908719097&k=rdG W9Nb&lb=1&s=X3

A total light collection of more than 48 hours (mostly Ha and OIII) between this and last year.

I have been struggling with the color balance and overall appearance, I am not yet convinced about the final result so all your comments will be appreciated. Perhaps less contrasted? Or less saturated? I look forward for your inputs!

Clear skies
Marco

Oh man these are deep. Just looking at the other shots also.

I think you have a secret space telescope for your own personal use lol.

Sorry, looks a little " posterised" and un-natural to me. The dynamic range is compressed and colour a little too blue.

Still a pretty image, and I can see some rolling their eyes, but hey, it often comes down to personal taste...and I call it as I see it

I can see where Peter's coming from with the posterising comment.

Still, it is a beautiful work of art; as are all your others.

Good to see you've got PixInsight tamed for mosaics!

I looked at the full size - it's amazing Marco.

That's a lot of work & a photo mosaic to be proud of.

Agree with Peter. The image looks quite flat and at original resolution shows this very well. It does look a little blue, but colour in NB tends to be dealers choice.

I am sure you will go over this several times more yet and I look forward to your future interpretations of the data.

Plenty of detail and the nebulosity stands out well from the starry background. Lot of other nice images on your site too!

This looks very vibrant Marco and provides a great journey surfing around the large version. The resolution of the finer features seems a little lower than I would have expected but zoomed out a bit it is a great field and has plenty of zing . Certainly not conventional in appearence so it won't totally please everyone but c'est la vie... Another great project executed very nicely....look out when I finally get an observatory!!! ....

Thanks everybody for the nice words and even more for the constructive critics, as I wrote the first one doubtful about this processing was me. Indeed it is an unconventional version, I have reprocessed with your feedbacks the image and now I have uploaded a more traditional one, using the same dataset.

Here is the new version

(here is the old one)

I would really appreciate to have your opinion on which one you prefer, my preference is for the second one

Below some comments to your mex:

As per Peter, thanks Paul for the comment, made me repro the image (above). Now let me know if the new version addressed the problems of the former one please

Thanks Mike, well, my FL is still pretty little and I didn't apply any deconvolution on the luminance, but definitely there is margin to improve as per your note, thanks mate

That looks remarkably like Marcus Davies rendition from back in March, that was a unique colour palette "look" then...interesting how trends can start huh?

Looks great Marco

Wow , I swear forgot about the image of Marcus (great image by the way!) and got a similar palette with a serendipity approach

So which one would you pick mate, the old "peculiar" one or the "deja vu" new version?

Hmmm? not sure really, I like both versions . From a true colour perspective I think the latest is closer to natural RGB but the first one is quite striking...toss a coin

Hi Marco,

I think both versions are amazing photographs that give us inspiration and that you should be proud of.

Thank you.

Ross.
