Dunno about this one, and if it's "of note" or not.
Not seen listed in the search database.

It might have a fairly high redshift, but on the other hand, it may be an intriguingly red galaxy. In fact that might be the reddest close-up thing I have seen on this forum so far! :o

I'd alert the Team to that if I were you.

Infuriatingly it doesn't have a redshift. There is a topic for the highest redshifts we can find, but as you will see, none of them look like that.

Not exactly sure how to "Alert the Team"

To whom are you referring?

Replied by PM, but you can send a message to Edd or one of the zookeepers on this forum. :)

It's not just me is it? This looks like a purplish-orangey-red dwarf/irregular galaxy and I am certain I have never seen anything like that on this forum . . . and believe me I do look at a lot of stuff . . . :o

NED has it as "[ISI96] 0354-0043", a "dE" .. dwarf elliptical ..

And for my thousandth post, I will return to being the stick in the mud.

I noticed that everything in this region has a reddish tinge to it.  Perhaps
the color is an imaging problem.  (There are green regions, why not red?)

SIMBAD shows it's in a catalogue of low surface brightness galaxies. I don't know if the colour is terribly unusual.

http://www.obspm.fr/actual/nouvelle/may03/lsb.en.shtml says red LSBs are rare, but I don't know how rare!

I don't know much about LSB galaxies... who in the team would?

Re: Very dim - high redshift? - another LSB - blue

LSB irregular, in blue (star forming?)

Sorry if I've raised false hopes and wasted scientist time . . . :(

It's always worth asking though I'm sure.

I'm astonished you'd think that Alice! That's not time wasted!

that should be incentive enough to keep looking for LSB's
