NGC1291 Ring Galaxy (16 minutes)

[alexch]

At Border Stargaze I stumbled across this one by accident surveying galaxies in Eridanus visually with my 22" dob. Sony NEX-5 replaced the eyepiece and after looking at the first image I thought my Paracorr fogged up but a quick computer search confirmed the ring was real. So I left the camera in for 30 minutes. A half of 30-second subs were okay (the other half had trailing from the Dobsonian mount errors) and the result is below.

It is way too noisy for any greater resolution but I thought it looked interesting. It fits the FoV nicely and I should add more subs later.

NGC1291: 32x30 seconds, ISO 6400, Sony NEX-5, 22" Dob.

Cheers,
Alex

An amazing object Alex.

I also have never seen this object before.

Thanks.

Ah ring galaxies rock, don't they :D Very nice image, and it's full of distant background galaxies to, very cool.

That's a beauty Alex.

That's cool you found a galaxy not often imaged.

Greg.

Ring galaxies are fantastic...great catch Alex!

[Ric]

A wonderful looking galaxy.

I've added this one to my imaging list as well.

Nice! Such a tough object.

Thanks Alex for an interesting image.
James Dunlop found this object in 1826, here is his description.

John Herschel had two positions for this galaxy and it ended up with two NGC numbers, 1269 and 1291.

Click on "NGC 1269 data" for some history.

It looks like a moon halo :)

Nice work Alex!

Exceedingly well captured and processed! I believe that NGC 1291 is the brightest ring galaxy in the sky but I could be wrong.

:D
She's a wee beauty.
I have a feeling that we're going to be seeing a lot more of her very soon.

If you like imaging galaxies that contain one or more ring structures, try "The Catalog of Southern Ringed Galaxies"(the CSRG) by Ron Buta.

The variety of rings and bars that are found in galaxies has been thoroughly explored and characterized by Ron Buta, and because of the complexity of these phenomena, it can be a bit tough to figure out what the galaxy classifications and the descriptive notes mean, for each and every galaxy in this catalogue.
(Each galaxy is classified and characterized using an elaborate descriptive scheme. )

(If you want some help, I can sort it out for you!)

If I ever get "a Round Tuit" I shall prepare, for iceinspace, an illustrated guide to the various types of ring structures that are found in galaxies.

The literature reference for this catalog is:
(1995), ApJS, 96, 39
and one good way to get the catalog is to access Buta's webpage:

http://bama.ua.edu/~rbuta/csrg/csrg.html (http://bama.ua.edu/%7Erbuta/csrg/csrg.html)

and then follow the link(s) to the catalog from this webpage.

_____________________

Another way to access this catalog is to use the "Vizier" service at CDS :

http://vizier.u-strasbg.fr (http://vizier.u-strasbg.fr/)

You put in "CSRG" into the search field in order to find the catalogue, and then you can find the catalog entry for any galaxy of interest.

Hey, that's alright huh?.. :thumbsup:

The ring is beautiful

Great little capture, love your 22" snapshots :thumbsup:

Very nice Alex. You really are getting some incredible results with your big dob.
Nice result which I am sure you will improve on with more exposure.
