NGC1097 with tidal streams

[gregbradley]

I was looking over this image I took last year and noticed it had more data to reveal.

There are 2 tidal streams of stars coming off this galaxy that were picked up in the image. It was taken during a night of excellent seeing.

I have processed it to show these tidal streams which seem to be more common with galaxies than perhaps first thought.

About 5 hours total exposure, FLI ML8300, Tak BRC250, Baader Clear RGB filters. Taken at my dark site observatory.

Very nice! I remember seeing a similar shot on Jay Gabany's website. Very well done indeed. Very good processing. Detailed and soft. :thumbsup::thumbsup::thumbsup:

No gradients, pristine tight stars , great S/N matched with tidy processing...nicely done indeed :thumbsup::thumbsup:

Wow – excellent – looks like the famed Ben Lexen’s winged keel. Nicely extracted

Great image Greg, just stunning.

To me, a long suffering Parramatta Eels fan, it looks like the Walking Eel Galaxy.

Well done Greg in teasing this detail out.
This is becoming a very popular pursuit it would seem and there has been a couple of APODs showing these tidal streams.

The BRC250/dark sky combination is certainly what is needed.

Great work
cheers

Yes there is also an ESO image showing it as well.



Thanks. I occasionally get it right. Now to do it regularly.



Thanks David. It was nice to see it there and bring it out and then check on the net to see a large scope had picked up the same thing so I was sure it wasn't some sort of gradient or artifact.



hehe, thanks.



Thanks Tom. I may end up being a tidal stream specialist!:lol:



You can have that name for it.



Thanks Martin. Yes it is the popular galaxy pursuit. Its nice to have one in the Southern Hemisphere.
