Since I started using the CCD to run longer and longer integrations over individual objects, and considering that the nights available for imaging are one or two per month (at best!) I started thinking in terms of projects. Well, one of the projects it is now concluded and it concerns this region. I had taken from Saint Barthélemy (AO) and the RGB Halfa on September 10, 2010, thinking that the object was practically completed (http://skymonsters.net/immagine.php?img=Sh2-129.jpg). Then, browsing the net for information related to this subject, I came across this little article: http://www.outters.fr/images%20site%...rte-OU4-eu.pdf
So I picked up the project again and last August, from Tortorici (ME) I integrated for 8 hours with the OIII filter in same field. I find the result very rewarding and I hope you like it too.
That's a tremendous effort; beautifully coloured and processed. I'm very surprised by your exposure lengths with the BabyQ, up to 1800secs! Based on the excellent result, they were necessary. It's a very interesting object, thanks for sharing.
Great picture Nicola. It does look like the extensions of a planetary nebula doesn't it? That's a lot of integration time. Well done on the processing too.
Very nice image. Love the twisted shells pushing out. The explanation at the AAIC this year of the expulsion of gases from a dying star is clearly demonstrated here albeit not of the end of a main sequence star.
This is a wonderful image of an object I had never seen before.
An off the beaten track image makes it even more appealing.
Just stunning.
Thanks for sharing.
Fantastic effort of a very obscure object, I believe this the best image available today of OU4. Remarkable it was obtained with a mere 85mm of aperture
Many thanks for your kind comments, I'm glad you found it interesting, as much as I thought when I started to image it. The only suggestion I have if you try it is...don't give up when you don't see almost anything on the single uncalibrated frame

Steve, think that I was even using the focal reducer!!
An amaizing capture of an awesome target Nicola, a very rewarding result after the long period of time to finally gather the data needed, Job well done
