Sh2-129 and the mysterious OU4

[Nicola]

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%20astro/decouverte-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.

Hello Nicola,

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. :thumbsup:

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.

That's a sensational image.

Beautiful image, Nicola

Lovely image and an intriguing object. Well done, Nicola!

Thanks for sharing Nicola. Very intriguing, interesting object.

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 :thumbsup::thumbsup::thumbsup:

Ah yes, can tell an Italian took that...its red and green! :P

Fantastico! and what an intriguing object, love the contrast between the green bubble against the red background :thumbsup:

Beautiful photo Nicole.

I love the contrast of colours.

thanks for posting such a very interesting image - foreground object sure does look like a bipolar PN - a big one.

[Nicola]

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 :)

Wonderful Nicola ... your best for me. The subject are incredible and the color are stunning like the contrast. Way to go.

All the best,
Leo

[Nicola]

Thanks Leo, much appreciated! :)

That is a beautiful and delicate result Nicola.

Steve, think that I was even using the focal reducer!! :rofl:

[Nicola]

Thank you John!

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 :thumbsup:

You've done well Nicola.
In this picture from Steffen Behnke - you can hardly see it.

I think people might start chasing this target now.
It must surely be worth an APOD to whoever can get the best pic?
Yours is the best I could find so far.
What an interesting target -
a planetary nebula close by & very large in apparent dimensions.
I wonder what an RH-200 would do with that target?

cheers
Allan

wow what an intricately delicate object, so complex yet so difficult to get - world class!!! fantastic effort

What a fascinating object.

A wonderful image Nicola.
