Unable to put a hi-res image on the web site for some reason - probably lack of €... :unsure:

Very nice image, Kinch!

Your stars look nice and round also.

The orange star left of centre sure looks very circular and smooth.
Great details on your website too.

Keep up the good work.

Aubrey.

Wow 30 Hrs. Great processing, lovely tight stars.

We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills

Thanks very much Aubrey & John. I don't think I have ever done an image with so many stars before. There was quite a bit of processing done to tighten them up (as you can imagine with 30 hours of total exposure). I am not sure I like that end result myself (i.e. so many small stars) - but it is a lot better than things looked without using 'deconvolution' in PixInsight.
It is an interesting subject nevertheless. I'll see about putting the SII, Ha & OII images up on the web page (soon) to show why the colours come as they do....especially that large blue (OIII) area at the bottom right. Although I slightly mixed the mapping, it is basically: R=SII, G=Ha (with green removed from the final image) and of course B=OIII. (Ha mixed back in as a Lum to help the detail. So: LRGB = Ha SII Ha OIII)

I have just now put up the SII, Ha & OIII thumbnails of the 3 images used to make the final. I also have been able to put a much higher resolution image up - available when you click on the image on the SH2-132 page.
