NGC 1097.... repro...eeeek!

[strongmanmike]

Well after looking at my NGC 1097 again (errr and Martins ridiculously good version :whistle:)...ummm...I decided to redo the processing...meah just cause :P

There were a few issues apparent so I removed the slight megenta cast, improved the star colour, improved the colour dynamics of the galaxy and brought out the HII regions a little better, tightened the stars, revealed a little more in the very core without disrespecting the light :P...and improved the background through a variation of DDP on the Lum (no noise reduction though)...phew...:lol:

What do you recon?

I like the colour better in this version, Mike. In case you're looking for reasons to do another repro :lol: the subtle shells around NGC 1097A aren't as visible in either version as I've seen in a few other images.

I must get my NCG 1097 finished one of these days so you can poke holes in it, Mike :D I have quite a queue of images that need to be processed. Unfortunately, I've been spending too many nights catching up on my day job.

Cheers,
Rick.

Don't recall seeing the previous version Mike, but this rendition looks the goods. You running AO these days? The detail in the core is something I'd expect from a much longer focal length and image scale than 1120mm scope.

[strongmanmike]

He he and yes I knew about the shell and it is there.. just not quite as delineated as I would like...probably needs more exposure and better seeing to reveal that one well

Thanks for the comments though :thumbsup:

Mike

[strongmanmike]

Cheers Jase, appreciate the feedback :)

AO??? naaah not in the mix yet, nor is PEC or ProTrack for that matter...just NJP power :lol:

Mike

[RickS]

Mike is using an ICX694 with smallish pixels (4.54 microns) so his image scale is around 0.8 arcsec/pixel despite the short focal length.

[strongmanmike]

Yes, that is true :) and it has helped with galaxies and PN's for sure...but still no real substitute for longer FL + AO, PEC and ProTrack on thse smaller objects..one day...one day :lol: the fast F3.8 is good though.

Boooootiful! :thumbsup::thumbsup:

[rustigsmed]

that is one seriously cool looking galaxy, you can really see the arms bending away from the plane. awesomely done as usual Mike!

Cheers!

I like it alot.... :thumbsup: Mi piace molto!!! :thumbsup:

Looks great Mike.
I can't compare the old to the new -
they have the same picture:

Yes I like that. That is super good.

[strongmanmike]

Thanks for checking it out guys...repos still have their uses :thumbsup:

Allan I am too ashamed to post the previous version :ashamed: :lol:

...although :scared3: you can peek at the previous thread thumbnail here (http://www.iceinspace.com.au/forum/showthread.php?t=112950)

Come on Mike - my Flickr photos show all my old DSLR failures.
It's good to see the improvement.
:)

[Shiraz]

yep, that's even better - very nice repro. regards Ray

[E_ri_k]

Looks great Mike :) Well done:thumbsup:

[RobF]

The repro is great Mike, but I think it needs a bit more magenta maybe? :whistle:
Actually another 10hrs data might help bring out those tones a little better? :evil:

[strongmanmike]

Ha-ha :rolleyes: :lol: :thumbsup:

[Paul Haese]

Yep like that colour, maybe could be a touch bluer, but personal preference. Good detail in the arms now.

[strongmanmike]

Thanks Paul, funny I was thinking it might be a tad too blue :lol:...so I guess I'd better leave it as is :thumbsup:

That's a magnificent looking image Mike, great colours and processing, I really like it. And the galaxy is such a cool target. I'll promptly add it to my todo list :D

I really look forward to getting back into imaging, I've been busy finishing the new scope for a while. Yesterday I put it up on the mount for the first time and it only needs the final tuning i.e. collimation, new flats/darks etc.

[strongmanmike]

Cheers Rolf :thumbsup: Sooo, any pictures of the new beast?:D

Mike

[SkyViking]

Cheers Mike, I have plenty of pics but have been too busy tinkering in the last couple of days to post them anywhere. It looks to be clear again tonight here :thumbsup:
Once the rain sets in I'll post a thorough update :P

The new Royce mirror seems superb. With the old 10" my FWHM was usually 2.5-3.5" and only once have I seen it below 2" in the two years I've been measuring...
Last night was first light with the new scope: In average seeing between clouds I got consistently 1.5-2" and lowest I saw was 1.37". That was just insane. :D

Anyway, I don't want to hijack your thread! :lol:

[strongmanmike]

Hey, quite alright...wow, that sounds pretty exciting :thumbsup:

What will you be doing with the department store quality, old antiquated, crappy 10" now? Guitar strings...reeeally :rolleyes: :lol:

Mike :P

[leinad]

Superb, love the composition too.

Mike,
you are starting to pick up some of the strangeness of the companion galaxy NGC 1097A.

Have you seen this image of it, taken by the VLT and VIMOS
(this is a cutout from ESO Public Image No. eso0438d)

152351

Nice angular resolution on this one!

Arguably, this little galaxy is a lot weirder than its big friend NGC 1097.

Bad Galaxy Man's puzzlers of the day;
What type of galaxy is this?
What Hubble type is it?
What is its structure?
What is its orientation in the sky?

It seems highly probable that while NGC 1097 seems to have some unusual outer arm structures due to a likely interaction with NGC 1097A, the big galaxy is modifying the little galaxy in a very major way.

Best Regards,
Robert

P.S.
I think that the origin of those structures in the Olsen-Sidonio deep field of Centaurus A should be modelled by some of the "pros".

[strongmanmike]

Yes the shells are just starting to show



Yes saw that, well the full frame anyway



Yes, be interesting huh?

Mike

[strongmanmike]

Cheers, glad it was of interest :thumbsup:

[Ross G]

The original looked great Mike.

This version is even better....a stunning galaxy photo!

ooooh and ahhhhhh

[allan gould]

Im amazed at the quality of images that IIS members are turning out at this point in time. I guess its a combination of great scopes, cameras and the marriage of computing and glass which shows when combined with talent and dedication. I wont name individuals but some of the images are just spectacular but it gives the rest of us something to aim for.
Oh, by the way - nice image Mike, way out of my league.

[LewisM]

Going to have to call you Captain Sidonio soon with all this talk of jets.

:)

Good images indeed, but I reckon there's some light pollution artifacts in there. Maybe someone struck a match 77km away from you Mike :)

[prokyon]

Hey man, that is fantastic! Great pic with many details and wonderful colors! :thumbsup:
