Not a regularly imaged galaxy, IC 5332 is a somewhat tenuous spiral galaxy with a very low surface brightness of just 23.8 mag/squ arc sec, making it a challenging target with elusive features that are hard to reveal well. Dark skies and some decent exposure are necessary for a good result and this may explain its relative obscurity, despite it's subtle beauty.
Despite one clouded hickup one night (grumble, grumble hurumff), I enjoyed some good clear dark skies over the past New Moon week and this was collected over three of them and as usual, although somewhat variable, the seeing was relatively stable and I discarded not one single sub
Regarding it's low surface brightness, in comparison, the notoriously low surface brightness galaxy in Pavo, NGC 6744, is over a magnitude brighter per squ arc sec!
Not many images of this one around, unsurprisingly Mike. It's an interesting galaxy but I think the plethora of funky small galaxies are the highlight for me. Lovely work!
Nicely done Mike. I imaged this one myself a long time ago and I know it's a difficult target so you've done well. I would possibly tone the saturation down a bit though as there's some colour noise creeping in.
In addition to the exquisite detail in the main target, the extreme faintness of the main target means that the distant galaxies are very prominent and add a lot.
Thats a tough target Mike - very well done. Colour is king for me and I love the magenta in the spiral arms
Pete
Thanks heaps Pete as pointed out by Steve below, there was a little colour noise but I have just removed as much as I can

Thanks Steve and yes it is really faint this one. Thanks for pointing out the residual colour noise too, I had removed much of it but you were quite right some remained, I have now manually gone and removed as much as I can without affecting the many small HII regions ...after zooming in it was indeed quite difficult to tell the noise from real detail, particularly there are a lot of HII regions...so I did my best referring to the Ha only data.

Cheers M&T, I really like this galaxy and the only other time I imaged it, waaaay back when, with my old LX200, it was next to impossible to render anything worthwhile...times they have'a changed

Well, arhem, as per the image credits ..there is 2hrs worth in there already Col just to enhance the HII regions a tad

Cheers Rick T'is funny how when one spends some time working on something that they used to think was a bit ? lack luster?...feelings can change I now think this is one of my favourite galaxy images I have done, I really like the subtlety of the delicate arms and the tight spiral detail in the core and it really reminded me of a delicate corsage
One of those images where you don't quite know where to look first, so much going on.
Do you look at the huge amount of star forming stuff in the arms? the arms themselves drawing you to the outer edges where there is some disorder of some sort which is pretty neat? and of the course the number of background galaxies splattered all over the place which as was said earlier have come out well.

Nice image!
Thnaks for haveing a good look Dave and glad you enjoyed it

I'd love to image that one but at Mag 10.6 - it's just too faint.
I don't know how you do it!
cheers

Thanks Al
I plug away like the rest of us really, I have some reasonably capable gear that just works with relatively little input and that helps a lot, the rest is good old fashioned imaging with very little automation and just making a hobby of it, you know?...just sitting by the river with a rod and the right bait in the water while sipping a cold beer on a deck chair on the bank and enjoying our Universe overhead
Nice one Mike. Our galactic education continues - another one from the road less travelled. And definitely lots of faint fuzzies to enjoy besides the main show.
Nice one Mike - great to see something different too. I guess targets like this are where F3.8 really shines eh? 17 hours is practically mega data territory for you - well done!
That's a horrible image of a beautiful galaxy...just kidding
Splendid work Mike, I really like how you maintained pleasant star colours while gently brining our attention to the main object by skilfully highlighting structures within the galaxy...
Nice image Mike. You got some nice colour there as well. I imaged this one recently as well. Both our setups are uniquely able to image these faint ones and bring them out. The Ha has added some nice colour there. I should do that myself whilst its still around.
Its a bit like NGC1232 this one and certainly one of the few side on spirals in the Southern Hemisphere.

Cheers Rob, as I said it is a challenging target, soooo would have been muuuch easier to have a shot aaaat saaay NGC 253? But been there done that...although I will probably do it again someday

Thanks Marcus, he, he, yeah 17hrs is just 20min short of my longest exposure ever with the AG12 ...didn't realise how close I was to that figure actually, should'a gone another 25min, just to break my record

Yeah sorry to have made a corsage out of a very faint clump of weeds Slaw, I'll try harder next time

Cheers Greg, yes when I look at your result and compare I can't help but think that you really need to move that amazing observatory of yours to Bigga mate and remote it, go on.... Of course, err?.. I haven't done it soooo I can't talk, huh?

Yeah I guess, a bit, although 1232 has a prominent central bar like NGC 6744's and well defined thin arms and is significantly brighter at 22.6 mag/squ arc sec....oh and don't forget that faint Sidonio jet!
haha
..there is 2hrs worth in there already Col 
...or heck, the bloody post even
