After showing my widefield image of this area to a friend, he sent me this thread. I used a FSQ for my image, so resolution isn't too good for detecting this bubble, but I found it.

I cranked up the contrast to get a better view of the bubble:

Hello,
I am a new member of this forum, sot let me present myself in a few lines. My name is Emmanuel Mallart, 46years old, I am a French astrophotographer, also involved in high precision scopes (Newton, Newton-Cassegrain, ...) and high precision mounts making.
You can see the equipement there, sorry th site is not yet translated in English : http://www.axisinstruments.com
Direct access to the mounts page :
http://www.axisinstruments.com/francais/produits/montures/montures-equatoriales.htm
For my pictures : http://www.astrophoto-mallart.com/francais/galerie/nouvelles/galerie_nouvelles.htm
I shooted this picture of NGC6888 region, were you can see easily the new bubble. It was captured last week-end using my homemade 16inch NewtonCassegrain used at Newton f:4 focus, and astrooptik 3" corrector and the STL11k + 6nm astrodon Ha filter. The global exposure is three hours.
You can see it on the French Astrosurf forum :

I hope you will enjoy !
Emmanuel

Sorry, my scope is not a 16" but a 12" Newton-Cassegrain.
I will post a picture of the setup soon.
Regards,
Emmanuel

Hello Emmanuel, I was coming to put a link for your picture, but the work is done 
Splendid view of this area

Just for update interest this object does show on the IPHAS survey but not yet in the publicly released bit. They said it was quite faint for them and only appeared on their highest quality images. As to be expexted it will appear in the PN catalogue form this survey when ever that comes out.

I take it I won't be sweeping this up with my BT100 binoculars? 
OTOH, I see a lot of the associated bright nebulosity around 6888; sometimes under REALLY dark skies it is hard to separate out 6888 from the surrounding field.

Thanks for the update, Owen.
Mr Bill adding the diameters of all your instruments should (perhaps) make it...

And by the way, do some very big dobson owner try to give a look at this nebula ?
In France, a forummate try from under a very good sky with a 22" and see nothing.

Perhaps you could try getting in touch with Jimi Lowrey in Fort Davis and he could have a go at it with Barbarella.

Hi Denis,
I had tried it shortly after you posted the new PN here using my 22", but without success. The contrast of the bubble to the "background" nebulosity is very small.

The APOD today :

Thanks Reiner for the report, and Bill for the suggestion. I'll try to contact Jimi Lowrey.

I'll chime in on the possible visibility of this ring... forget it! The excessively low surface brightness, combined with the *very* small ring width, will render this one invisible to the human eye with any instrument/filter conceivable. After all, just look at the high degree of processing required just to make it barely visible in DEEP images.

I, too, see a second bubble in this APOD picture. It is over 1/3 the diameter of the newly discovered bubble, and in the APOD image it is immediately to the larger bubble's left, and overlaps the larger bubble by a little over 1/3 its diameter. I see it also in the contrast-enhanced image posted earlier by John T.
I believe this second bubble might be created by some chance curves of faint stars that seem to outline a circular area. But I would like to see the image contrast-enhanced a bit more. We could be looking at two new "bubble" planetaries.

They are many nebulosities in this sector and also many star and chain star.
I don't see other evidence of another bubble.
I think the best image we have to work on this area is the one of Keith Quattrocchi and Mel Helm which make the Apod.
You can try to enhance the large version of this one to search more precisely : http://antwrp.gsfc.nasa.gov/apod/image/0811/UndesignatedBubbleFC_kbqmh2546.jpg
