Soap Bubble nebula bi-colour

[Lars]

Here is my second attempt with a bi-colour image, the soap bubble nebula. I tried to follow Cannistra's method, but still learning and didn't quite get the result I wanted. Probably need to reshoot it some night with longer subs and less wind as the heavy winds forced me to take short subs but I still had to throw away quite a bunch.

This area is as rich in Ha as it is deficient in OIII and the nebula became more visible when I desaturated the red.

The soap bubble is about 5ly in diameter with an apparent size of 260" and lies about 4000ly away in Cygnus.

Imaged with Orion AG12/Atik 460

Ha 28x4 min Bin2, OIII 43x4 min Bin2.

That's nice - very delicate bubble I tried to find this last night without any succes!

Thats a great capture and I imagine a hard one to get well done

That's the first time I've ever seen it. I *think* I've seen it on other people's pictures when they say it's there. That is a fantastic capture.

That's lovely - I have yet to capture this elusive beauty.

Never heard of this object but the name if spot on. Great picture of a very interesting object.

Thanks for your kind comments. Yes, it is very weak, but it is a great help to have a F/3.8 photon bucket to work with.

I decided to crop it and tweak it (I hope!) a little before I move on to the next target.

Btw, does anybody know how I can publish a thumbnail and not only the large size?

Wow, stunning! Never seen this nebula so detailed before!!!

[farunj]

Wow!! Absolutely stunning!!

Wonderful Lovely delicate looking bubble

Very nice capture! It is really amazing that an object 5 ly across could still be such a neat sphere

[Bizibilder]

Lovely picture!

If you post a link to an album or remote site (eg photobucket) then you get the picture full size. To get a thumbnail you have to upload the picture to the thread directly (and are limited on size). (I think!).

[Lars]

Thanks for your comments.

Roger, I try to attach it as a file directly to the thread and it looks ok in the preview. Fingers crossed this works.

Thanks again.

That's really impressive. You've done well to get it to show so sharply. I'm surpised by your short Ha subs, though. Why not go for a bit longer? I do 15 or 20 minutes at F3.9.

Thanks for the comment Olly.

The short subs are only due to the heavy wind gusts that night. I started out with longer subs but realized it wouldn't work, so I went for short subs and binned them. I remember I threw away about 30% of the OIII subs, probably a little less of the Ha. I would have liked to throw away even more but that wouldn't have left much signal.
