A billowing galaxy in Leo

Cobbled together over 6 nights from 19 March to 17 May in varying conditions, this was a challenge to collect and put together....

NGC 3521 is a beautiful colourful and glowing galaxy in Leo that is often overlooked for the more famous Leo Triplet of galaxies. The galaxy has a faint but complex system of billowing outer star clouds and if you look closely, a deep exposure like this also reveals a very faint extended halo arching out to the right and above the galaxy, with shell structure evident and well noticeable in a high contrast stretch. The galaxy seems to have a two tiered spiral structure (like a spring) too...?

Faint Extended Halo (High contrast stretch)

Wow! That galaxy looks like a monster! Definitely looks like its double stacked.

Incredible view, Mike! Great job!

Great job on this one Mike. Looks like a R J Gabany galaxy shot.

That's a beauty Mike. I esp like that little galaxy at 9 o'clock - being drawn into the big guy?

Lovely work, Mike! It's a very cool galaxy and you captured and processed it masterfully.

Twenty years ago we would have had no idea that so much was going on around a galaxy like this. Much turmoil.

Stunning impressive amazing. A shot to come back to many times.

Nice work Mike. 13.5 hours is a lot of exposure at F3.8.

Greg.

Great detail, good colour and very nicely processed Mike. It has now gone onto my imaging list. Well done.

Wow Mike, looks almost 3D. Great job of post processing too, oodles of information in those subs. Must have had great seeing!

Well done mike,love all those little fellas floating around the big guy.
I observed this galaxy only a few days ago,it's good even visually.
Cheers

Well done Mike. Lovely colours. Could do with some more focal length but its a pleasure to see the faint halo that would likely take quadruple the exposure time to extract with a slower scope.

A beautiful image of a fascinating galaxy Mike!! I like your colour saturation as well!

Cheers everybody

Steve, yeah I just had a squiz at RJ's actually and while his is a little grander (20" scope and all) I see what you mean (nice compliment)...but I notice the features in his billowing star clouds don't really match mine completely ....not sure why but I did almost exclusively global adjustments only to my data so I am confident the shapes and structures visible around my version are true and not manipulated, ie they are real.

Logan, I think all the other galaxies in the frame are background ones

Meru, actually the seeing wasn't really that good any night and when it was, it was only for short periods...one of the reasons I would love to live in the Andes being image time starved and not automated I tend to need to use my less than optimal data

Ron, Yeah I had a look at it a few times through the 12" dob while imaging was chugging along...can't say the view was anything like this image though

Jase, yeah wouldn't we all...and a better site, and AO and automation etc ...but in the end we do what we can with what we have. My image scale is pretty perfect for galaxies at 0.83"/pix so that's as good as a bigger pix camera on a longer focal length scope anyway, so 6 of one really

Lewis, (you idiot )....those two really faint outer arcs are almost like a jet, ie can't see'em on any other image of this galaxy out there

Marcus...come on, you looove saturation, I know I have turned you, I know I have ....

Cheers again everyone

Mike

Very nice Mike, but I would prefer a tone down of the red inner regions and a saturation boost to the blue outer ones. Nice job on the halo.

Now the insults. Fine. No jet.. OK... so where is the fluoro pink then? This is a plagiarised image if there is no signature Sidonio Pink.
