Bubble Wide Ha

[Allinthehead]

Another ha image with rgb in mind for later. Something that struck me while gathering information on the bubble is the size of it. 7 light years across. This thing would reach Alpha Centauri and beyond if it were in our solar system. Another interesting tit bit is that the star which illuminates the bubble is actually in the center but appears off centre, and is 45 times more massive than Sol.

Will be interesting to see it in RGB.

Lovely framing and context Richard. I generally prefer these wider scapes as b&w grey scale but also interested to see the finished rgb.

I hope so. I think there's some interesting blue nebulosity in the ha region above the bubble.

Thanks i'll tag you in the final version.

Nice! With that scope of yours, you can finish an image in no-time compared to others

There's also something below the area

A nice example from our colleague @Rodd

Thanks Alex. Yes i considered framing it with the Lobster Claw, maybe mosaic time. ?

Yes, that's how I tried to be subtle

Not often framed this wide, very refreshing to see the Bubble in context and I'm sure will be a delight when complete.

Thanks Barry, this one could take a while as the devil on my shoulder @moise212 has put ideas of mosaics in my head.

I also have some data on this target from last year, but the processing skills at that time didn't help too much. I can try to reprocess, but I should probably get better data too.

Anyway, you know that you keep the resolution you have now, you just extend the area... that will be about 4600x6800 pixels or a ~60x40cm high res print at 300dpi ?
