The invisible arms of NGC 1512

NGC 1512 is a lovely ring galaxy with a prominent bar and companion galaxy in Horologium. It's quite modest in size with the main visible component around 9' X 5' and shines at Mag 11 with a low surface brightness of just 22.7 mag/squ arc sec

The cool thing is, I saw a Galaxy Evolution Explorer Satellite (GALEX) image taken in UV of NGC 1512 and it showed some otherwise invisible or almost invisible (in visible light) outer arms extending a long way form the galaxy plus a bit of a tangle of shorter faint arms, all looking like a complex history of interactions...and I thought hmm? I wonder what the AG12 could get with a bit of exposure time

Well here is the answer

NGC 1512

Inside the core

Comparison with GALEX satellite image (hopefully I'm not a deluded emperor this time )

Comparison with UK Schmidt

Well..at 10hrs it is almost Mega data Paul and since it was through a 12" at F3.8.. is probably equivalent to about 50+hrs through a 4" @ F8 and marks the longest exposure I have taken so far with the AG12 YAAAY

You keep excelling yourself every time I see a pic you take. This is no exception and it's a damn great shot

Nice Mike! Definitely no substitute for a bit of exposure.

Cheers

That's a great shot Mike -
I can't find a better amateur pic of NGC 1512.

cheers

Great work Mike!

Like the full field version best, the spiral arms look like they have been disrupted.

Cheers,

Justin.

Thanks for checking it out and passing comment guys

Thanks a lot Carl, I am really enjoying imaging galaxies at the moment...could ya tell?

Cheers Allan too, glad you think so I couldn't find many amateur images period

Yeah I like this one. Maybe a little blue magenta, but heaps of cool detail.

For the record though it is a 4" f5.6, so that would make it 28 hours instead of 50.

Needs more data though still. Another 10 hours it would look slick, slick slick. So mega up dude.

Ahh huuuh....

Soooo, a galaxy I have NEVER seen posted on IIS before and it reveals things that are outside the realm of the usual NGC 253 or Lagoon Nebula (love the Lagoon Marc ) aaaand it is just too magenta/blue?? geeeez

3 X the aperture and two F-stops...hmmm? I think the mathematicians out there might be able to clarify things here...any takers?

That's a good pick up of the faint arm, Eridanus has so many galaxies perhaps you could try NGC1532.
