Ngc 1097

[richardo (Rich)]

Hi all.
Amazing that during the last few days it has been really poor with cloud and wind.. , but last night included, the skies remarkably cleared.
There has been some upper level smoke haze from the fires in Alice Springs that has played havoc with my focus...
But managed to get some time on Ngc1097.
Haven't imaged this for a long while so it was good to revisit it and see what better results I could obtain, albeit not in pristine conditions.

For a look please hit the thumb on my front page

All the best

Another sensational image.

That is a wonderful 1097. You got 2 of the 3 tidal streams there. There is another fainter jet on the bottom right to be gotten that is very very faint.

That is a good and deep image, Rich.

The unusual optically-luminous material near to the small peculiar lenticular (type S0) Companion Galaxy is extremely well shown.

A lot of these bright southern galaxies are only now getting imaging done at the depth that had been achieved for prominent northern galaxies in the past.

I am sure that there are discoveries to be made in imagery as deep as yours.

The little S0 galaxy is, in itself, an unusual object, as can be seen in the images of NGC 1097 at www.eso.org

Rich,lovely image I observed 1097 a couple of nights ago with my 16" scope as part of my Supenova search .
Ngc 1097A is the Dwarf elliptical galaxy at 42.000 light years from the center of NGC1097,it was like a fuzzy stellar blob but on nights of good seeing is quite a bright object.
Cheers

Heck Rich, what a stunner. Job very well done there.
When I stop to think about exactly what it is that appeals so much I think it's the the subtle warm colours you've achieved in the centre showing great dust detail, but also the blues in the outer arms - wonderful to see a quality image that brings out bluish hues in a galaxy!

Thanks for sharing.

Getting those jets is very impressive indeed and colours are just amazing.

Thanks Greg! Yes was happy to see those jets even in the single exposures..
The others, 3 & 4 are definitely super faint.. I'll have to increase my exposure lengths next time to get them down..

Thanks for the nice comments and info Robert!..
I do try to keep an comparative eye open when I look at what others have done on these galaxies... just incase there's a SN ..
I missed out on one by a day.. but that was quite a strange one as it went off in between two nebulas.

Hi Ron and thank you!
It would look great through the eye piece on a nice big scope and dark skies for sure....
Good luck with your SN searches!

Cheers for that Rob!
Putting in the time on colour helped me saturate it while using the lum to add plenty of highlights.
I was surprised there is so much new star activity along the arms of this galaxy.

Hi John, thanks for that!
The clarity wasn't all that great on the first couple of nights so was happy enough with the result in the lum after teasing more details out.. the colour came together nicely which made processing fairly straight forward.

Thanks again all for your nice comments.

All the best

Sensational work Rich. I dig the tidal streams and what looks like jets. Such a lovely looking galaxy. I have never seen this galaxy imaged before so it is such a special treat. Excellent work.

[jase (Jason)]

Absolutely pumping them out Rich. Lovely work all round. This and NGC300 are probably your best galaxy images to date. Whatever you are doing, keep doing it! The super faint structure and jets (possible star streams from the interaction) look awesome. Very well done.

[Martin Pugh]

I agree, very well done Rich.

Congratulations,

fantastic result...

Hi Rich,

What a great galaxy photo.

Amazing, colours and detail.

I would love to be able to take photos like this one day.


Thanks.

Ross.

[Star Catcher (Ted Dobosz)]

Wonderful image! Love the detail.

Ted

[Stevec35 (Steve)]

Now that's a seriously good NGC 1097 there Rich. I love the colour and the nice natural appearance. You could probably work on the centre a bit to get even more detail.

Cheers

Lovely image to view and pan around, the stars look great too.

Your OAG looks to have assisted your results nicely

One day I'll get back out there too

As can be seen from this VLT image at less than 1 arcseconds resolution, the small companion galaxy NGC 1097A looks very strange.



If there is no immediate recognition of which morphological class (Hubble type) a galaxy belongs to, one way to decide where it is in the orthodox Hubble Sequence is to ask: "Is this an elliptical galaxy?", "Is this an S0 galaxy?", etc.

But it is really hard to decide what type of galaxy this is, in the absence of information about its three-dimensional shape and about how the stars within it move.....
A Nucleated Dwarf Elliptical galaxy? An S0 galaxy?
Hmmmmm........

It is really hard to tell what type of galaxy this is, as the concept of a spheroid fits the observed structure moderately well, but the concept of a disk also fits the observed structure moderately well.

These Hubble "types" are conceptual templates (morphological classes) that do not apply to all known galaxies, though they are widely applicable in the local galaxy populations at the current time in the evolution of the universe.

You can find quite a lot of galaxies that look like this in very distant Galaxy Cluster environments;
yet this is not a familiar look, to us, because the nearby galaxy population contains very few galaxies that look like this.

Any punters as to what is going on in this galaxy?

Absolutely magnificent image.Thanks for the view.

Very very nice Richardo, another great shot in your collection! You have several really impressive images in you home page..

Hey Paul, thanks mate!
Was lucky with the weather and never thought I'd get enough time..

Thanks a heap Jase!... definitely the extra time on the subs has helped bucket loads as now I'm picking up a lot more detail... the system is working well with the OAG..

Cheers Ross... it's all a lot of time and investment.. even when you don't have the money... but the bug bites hard as i'm sure you know!
But the end results are the pay off

Thanks Steve for the nice comments... yeah I've pretty much pushed the core as far as it will go now... contrast/ sharpening.. any more and it starts showing up course and pixellated.

Cheers Big Migel!
Yes the OAG has certainly helped heaps mate... I've never had stars line up spot on before... so I had to start dithering in between each exposure.. yep certainly something new for me!
Hope you can get out soon ol' chap, miss your images and especially with Agie!

Cheers all for your great comments!

All the best

Hi Robert, as usual, thanks for the extra info... lots of stuff about on this galaxy!

I'll give it a go...
It is very similar in appearance to another galaxy I had imaged earlier on in the year.
It appears to have been stripped of all its new and mid age star formation, leaving very little in the way of HII and star building matter... only some odd, old stars and dust from its core are only now being extracted. It could have been a Sba galaxy in its life, the weird non uniformity of 1097's arms about 1097A could be a tell tale sign.. or whether it was an Elliptic galaxy, the bar formation is the effects of an extreme tug of war between 1097's arms and the 'disrupted' non uniformity of 1097's arms are from 1097As blackhole core...
This of course is a very simplistic non scientific highly speculative account from some one with little scientific knowledge..... so my apologies in advance

Thanks Marco. Have had a not so bad year weather wise as there's been some good nights which certainly helps in this game.! Lots of little upgrades which have also made life a little easier.

Cheers guys for your great comments.
Muchly appreciated!

All the best
