Bubble in narrow band

Hi all,

Here is a Bubble image taken with narrow band filters (O3, Ha, S2). We used two scopes and 2 cameras. The Ha portion was taken by Gilles Cohen in France using a 155EDF refractor and ST8 camera at F7 focal ratio. The O3 and S2 portion was taken by me here in hazy Illinois with my 160EDF refractor and ST10XE camera.

There is only about 1 hour total exposure for each color, so the image is not particularly deep. It really needs about 4 to 8 times this exposure level to do it justice, and we plan to shoot more if the weather permits.

Roland,

Nice color on the bubble. It looks as if the bubble itself is contributing lots of OIII signal......I wonder if it would show up in Hydrogen Beta.

For those of you not familiar with narrowband imaging who may not fully appreciate this image, here is an image with a 20" RC and 24 hours! of exposure:

The OIII and the SII components in narrowband imaging are usually exceedingly dim. I was taking some SII exposures last night, and even though the subexposures were one hour long, I still couldn't see my object in the subs.
That's an excellent start, Rolando. Exquisite detail.

Roland,
Nice shot of the Bubble. I like that we are seeing more and more narrowband images on the forum. It gives a new perspective on some old friends.

Awesome detail !

OUT OF THIS WORLD.... literally! 8)
Beautiful detail Roland...

I don't recall ever seeing the Bubble in Narrowband before... excellent!

I'm most certainly looking forward to the version with more data...
