Super distorted galaxy NGC1316

This galaxy is huge and its heavily distorted.

CDK 17 FLI ML16.

Very nicely done, and certainly an intriguing object. ....but the caption reads LRGB...yet it looks like L only. Colour still to come?

That's a nice NGC 1316 Greg although it looks a bit monochrome. There are lots of nice dust lanes at the centre that you could probably work on to get them to stand out a bit better.

Wow! Nice one - Havn't seen that one before - sure is some cool stuff up there

Just this morning I was chatting with an astrophysicist about Hoag's object - Wonder if you or Peter W or any of the other long FL users here have had a crack at that one?

Cheers

Yes it is quite monochrome. I only got 1 red sub which isn't helping but the galaxy itself doesn't seem to have any colour. I looked at other examples.
Boosting saturation did not do anything either. But I was happy to get the shell structure and large extent of this galaxy. Its quite enormous really.

Next time I will try to get some more RGB and add to it.

Thanks Steve. Yes its quite lacking colour not that this galaxy has much. There might be some more detail I could bring out in the core but not a lot more than shown.

Thanks Andy. Does Hoag's object have an NGC number? I think I may have seen an image of that just last night if its the same one. Its a red nebula with a blue O111 type semi rectangle in the middle of it?

Greg.

It looks pretty small. I'll do a 10minute sub next time out and see if it shows up.


Is it up at the moment?

I believe it's in Serpens, so maybe mid-year?

A beautiful image of a fascinating but less commonly imaged object.

It seems from our reading that it's in the same camp as NGC 5128: an elliptical swallowing a spiral, hence the general lack of shape but some twisty dust lanes. A difference is that the Hamburger has lots of bright blue star formation but the Hubble shot of this one doesn't show that. A gentler galaxy crash!

Excellent work.

Cheers Andy. I'll check it out later in the year then but I suspect its very small.

Good start Greg, but you can get good colour and detail out of both galaxies. I spent a bit of time on this galaxy but needed a better guide star position. I may go over it again one day in the future.

Oh yes, that does show a lot of colour. I'll get more rgb data and add to it later on. I mainly wanted to image this galaxy again to show the extended distorted bits which came up well in the luminance but more colour is needed for sure.

Now in full colour

Oh goody, I found some colour data I had from a few years ago.

Plenty of colour now!

Same link:

https://pbase.com/gregbradley/image/168843238/large

Its close to double the exposure time now.

Thanks Geoff.

I am glad I was able to use the earlier data to bring it to life, it had the detail but not the colour before. The advantages of keeping a library of your past images and the power of RegiStar to make it all compatible.

Greg.

Hi Greg,
that's a great capture.
It's the kind of target that could do with larger exposure time
as it's at Mag 9.
Paul is probably on the money with 18 hours.


cheers
Allan

Yes it certainly could. More is always better. Practicalities though get in the way!

It's a fascinating object and that 17" of yours sure looks like it's delivering nice data. One question - looking closely at your original and updated versions, it seems as if the registration step has gone awry and there's a bit of a mismatch in the data before integrating. There's a nice small spiral and a lot of moderate brightness stars below and slightly left that appear to be repeated.
Either that or my eyes are really that bad...
cheers,
Andrew.

Thanks Andrew. Oh dear I think that is an error when using Registar. I aligned an older image that has good colour with the current data which lacks colour. Something missed but just in that area. Weird. I can redo it as it was late in the processing.

Its now fixed. Thanks for the tip.

Thanks Tim.

Its one of the more interesting southern galaxies.
