Taken in NB as Ha Ha,SII OIII 30mins subs total exposure some 42 hrs.
Its very dim, the brightest bits in 3nm Ha are about 50 IDUs above the background.
I cant find a name or any designation for it for the life of me, ive checked stellarium,astrometry.net, and others and nothin. You can vaguely see it in the stellarium home screen and i can just see it in a very few wide angle pics but no one bothers to annotate it.
Its location is RA 04 53 57 DEC -70 00 42.
Im not really just asking for what it is, more where do I look?.
Cheers
Fred
Thanks Trevor. Weathers been good lately at siding spring, finally .

Thats it, that would be a classy name for sure

Peter and Geoff. Thanks guys.
Well, pointing is not perfect right now but good enough. I was aiming for NGC1848 but where i landed was a bit dull so I nudged around a bit and this popped up. I then log a star in the field to get me back next session.

Then there is the weather
Thanks Peter. Wow, that really does pop in your widefield
Your rendition must be deep!. There is quite a bit going on in that field, perhaps thats why noone has bothered to name it, but a lot smaller objects near it are labeled, i wonder if its in some obscure catalog noone uses. Ive tried all I could find. its a puzzle.
I'm not (nor will be) an astrophotographer, but I really like seeing what you lot do.
What a wonderful image!
Your question got me very badly distracted from work. After updating and correcting some things in my Stellarium, this is what I found: after turning on all DSO catalogues, setting DSO markers and hints at max, and removing all magnitude limits - almost nothing to be seen at those coordinates!
The basic Deep-sky objects background images shows the faintest of edges on the east side, but when turning on instead the Digitized Sky Survey (TOAST), your bubble could be very faintly seen.
Stellarium reports the position about:
RA/Dec (J2000): 4h 54m 01.95s / -70° 00' 08.0"
RA/Dec (on date): 4h 53m 52.23s / -69° 57' 49.8"
Another way for others to find it: it is sitting in the centre of the triangle of three identified star clusters:
NGC 1711
NGC 1751
NGC 1766
As to where else you could search for info, no idea, sorry, so can’t help further at the moment. Hopefully some professional astronomers could help.
Thanks Peter for your image too. You AP people bring out things the rest of us just can't see, so thanks.

Thanks for the effort Barry, sorry for the distraction from work, but you know, sacrifices for science .
I did pretty much what you did in Stallarium. Stallarium seems pretty comprehensive, as does astrometry.com I dont know if any other app has more data.
Peters WF shot shows its a fair size and obvious, im sure vast numbers of people have seen it before and wondered what it is. Makes me wonder how many other objects there are without designations!, perhaps this is common.
If it doesn't have a name, I guess not many would image it at long FLs, given you cant just look it up in a catalog and slew to it.
I cant see other efforts on the web either, without a name to search on, bit frustrating.
I suspect, really, its in some catalog, must be

Thanks Adam, I got lucky this time with random slewing, happens vary rarely.
My bad....just did a plate solve and it would seem if this little sucker is near NGC 1848 it is not
clear in my wide field image (NGC 1848 is lower left). I mis-identified the object
Had hoped to give it an ID.....it will have to remain a mystery for now.

Still distracting me.
I've gone a little cross-eyed comparing images, but IF we have the right coordinates (and it seems you do), then it is not in Peter's image. NGC 1848 is lower left, above Beta Mensae. Of the 3 NGCs I mentioned above only 1766 is visible in Peter's plate solve image and shells image. Fred's bubble, along with 1751 and 1711, are below the image border, almost directly below NGC 1791.
It does seem surprising that there is no designation, or it shows there are still things to identify.
Oh dear ,astrometry.net also showed an image of another plate solve attempt which was titled "N_185".
And blow me down, on googling N_185, I see Astrodon has imaged it.
Dons description:
Description
N185 nebula is a nearly circular 6.7 arcminute super bubble in the northwest portion of the Large Magellanic Cloud (LMC) 170,000 light years distant in the southern constellation of Mensa.
Sorry for the confusion guys. What catalog is "N" ?
Oh OK. When I say near NGC1848, thats where I started the random slew, it could have been a largeish slew. Perhaps ignor the NGC1848 reference.
I plate solved the image in astrometry.net and it came up with the coordinates I and Barry posted convincingly. astrometry.net also showed an image of another plate solve attempt, it was the same.
Im wondering if it does have a designation but was missed in one catalog and every other publication just copied data from it.
The object does show up in a SIMBAD search of your co-ordinates (attached)
When I did the search however, it returned 900 objects in a 1/4 degree
space.
