Looking into a Seyfert galaxy in Horologium

[strongmanmike]

Part of the Dorado group of galaxies, NGC 1433 is a modest sized 6' X 5' barred spiral galaxy with a double ring structure located in the southern constellation of Horologium.
At a modest distance of 30 million light years from Earth, it is a Seyfert galaxy with an active galactic nuclei. NGC 1433 is also known as PGC 13586 or (apparently..?) Miltron's Galaxy.

As is regularly the case and helped by the good seeing, my kit worked flawlessly all three nights and I didn't need to chuck a single sub frame of the 15.5hrs collected :D

While not up to the standards of Cerro Tololo and Mt Lemmon et al...the Wallaroo seeing was relatively kind to me on two of the three nights (luckily both when I was gathering the 11 hours of luminance) and this galaxy exhibits mostly very fine structural features ..so I have made a comparison with HST to help identify what I have managed to differentiate deep within the galaxy.

Hope you enjoy :)

:thumbsup:
Nice colour Mike. Not over the top super saturated stuff. This porridge is just right...

[Stevec35]

Nicely done Mike. It looks very like NGC 1097

Cheers

Steve

[strongmanmike]

Cheers guys...and glad you liked the porridge little bear :) and Steve, I agree, definitely some similarities with 1097. Actually there are quite a few similar ring Seyfert galaxies out there.

Great picture Mike & it's an interesting galaxy too:

Another off the beaten track target, Mike? I haven't seen that one before. Expertly captured and processed, as we'd expect :thumbsup:

Cheers,
Rick.

[strongmanmike]

Cheers Alan, yes I saw that piece :)



Thanks Rick :thumbsup:..it's funny, there are just so many amazing and or cool and beautiful things to shoot up there. I think many find themselves thinking that the popular targets (and I have shot my fair share of'em :P) are the only ones worth shooting...when they clearly aren't :)

Mike

[rally]

Thanks Mike
Very pretty indeed

[atalas]

Horo who?:lol:jokes aside.....great galaxy shot Mike:thumbsup:

[gregbradley]

That's a beauty. Good to see a new galaxy.

Greg.

[Atmos]

Very nice Mike, well done! :thumbsup:

[Bassnut]

Geez, thats good Mike, the detail towards the core is excellent and the colour is excellent too. Thats a lot of exposure time for RGB, paid off. Cant see any diff with the HST pic, dont know why they bother with it.

[strongmanmike]

Thanks for checking her out guys, glad it was worth a look..and Fred, I agree, meah!.. Hubble Shmubble :shrug:... :lol: Seriously though, when we lowly Earth bound mortals expose through our wonderfully fresh and life giving but pea soup atmosphere...it is nice to kinda try and gauge what we have actually captured..aaand what we haven't....although you can see the HII regions in mine at least :P

Mike

[Andy01]

Pretty cool Mike - havn't seen that one before - you've done a great job with it too, amazing what's out there :thumbsup:

[Slawomir]

Not only H2 regions but also dark lines of cooler galactic dust that block the stars behind them :thumbsup:

[strongmanmike]

Thanks Andy, seeing is king for good galaxy images and I got lucky for this project :)



Yes, quite an intricate network of them within this galaxy too.

Mike

[Placidus]

Very beautiful and well photographed. The symmetry (and slight departure from symmetry) is lovely, as is the sharp and accurate capture of the intriguing ring of dust. And the important bright centre is not burned out!

[Adriano]

Very beautiful galaxy. Thanks for posting.

[cometcatcher]

One of the best images of it out there. Better colour than Hubble too.

[rogerg]

Love it ... small and obscure :)

[strongmanmike]

The symmetry-yet-not was something that I liked too guys, I think we have similar perceptive biases :thumbsup:



Grazie Adriano



Thanks heaps, I was happy with the result too :D



Shouldn't be though really...just misses out on the publicity it deserves :)

Mike

[PRejto]

Great image, Mike. I love the way the colour looks. Seems perfect!

Peter

[strongmanmike]

Thanks a lot Peter, the galaxy details are pretty subtle and fine, so I was quite happy with that part of the result too :)

Mike

[Geoff45]

Nice one Mike. It was on my list for Sunday, but the weather didn't feel like cooperating.
You've handled the processing nicely--detail right down to the core and then out to the faint arms.
Geoff

[strongmanmike]

Cheers Geoff :thumbsup: yes, the lack of attention this little beauty receives is somewhat puzzling. I'm over respecting the light too, I like to see the details in the bright areas but having said that, I did try to keep the dynamic range close to reality.

Mike

[Shiraz]

thanks for finding this beautiful object - an outstanding image.
kept coming back for another view.

[gregbradley]

Just looking at that image again. Its really quite catching. You got some great Ha areas and the yellow core and processing overall is very good.

One of your better images I think Mike. Pushing that setup to the extreme there as well. Perhaps what you would get all the time with an AO unit?

Greg.

[Phil Hart]

Tis a lovely view.. echo the other sentiments.. nicely colour balanced galaxy and wonderful shading/detail in the core that doesn't feel pushed at all in the full frame view.

Hi Mike,

A great galaxy and a great image!

Awesome!
Cheers,
Tim

[strongmanmike]

Thanks Ray, glad it caused a second look, always a good sign you have done something right at least :P :thumbsup:



Thanks Greg, glad ya think so mate :thumbsup:

I have to say my seeing in recent months (in fact most of this year) has not been poor too often and is often pretty good and when this happens it makes all the difference, it is that simple. Sure an AO might help on those good nights but it might not be as dramatic as expected, my OAG errors are minuscule (http://www.pbase.com/strongmanmike2002/image/163975596/original) in those sort of conditions anyway...:shrug: As I said in 15.5hrs worth of LHaRGB subs, I did not need to discard a single one :shrug:...anyway, can't afford an AO unit and given my system is working so well all the time (touch wood) I dunni wanna touch aaaanyyyything Jock :lol:



Thanks Phil :thumbsup:



Glad you liked it Tim :)

Mike

[marc4darkskies]

What a great shot! :thumbsup: Love it! :love: Obscure AND beautiful at the same time! What a difference good seeing makes eh?

[strongmanmike]

So glad you liked it Marcus, I was happy with the result and yes always good when the seeing is settled :)

You been away?

Mike

[andyc]

Well I see that I'm about a page and a bit behind in my "oohh it looks like NGC1097" comment, but hey, it does! And that's a great shot again Mike, must be a good feeling not to chuck a single sub :lol:

[strongmanmike]

Cheers Andy, yes I agree, a little like 1097 but a lot like NGC 1512 (http://www.pbase.com/strongmanmike2002/ngc_1512_in_horologium) (which is also in Horologium) but without the distorting effect of a companion.

I rarely have to discard subs, except due to cloud or really bright satellites if they go right through the object .

Mike

[marc4darkskies]

Yep, was in the US for 3 weeks visiting friends and family. Had a ball!

Sadly, I don't see one clear night coming my way - all the way out to as far as CFN predicts :( I'll have to live vicariously through images like this I guess.

Again, this is a lovely image Mike! :thumbsup: Not sure I'd bother with a Hubble comparison though :question: :lol:

[strongmanmike]

Ah yes, I do recall seeing something on FB now, glad you had a good time mate :thumbsup:

Move to the Canberra region..and you can come to the brewery I live above on a regular basis then :D

Meah, well, I recon it's great fun and worthwhile :P...and a great way to determine what is real detail and what is really just bright worms or dots induced by decon and wavelets and what is not ;)....neither of which you will find in my work of course :D

Mike
