I had dreadful problems with capturing this image due to equipment problems, see my thread:

This has resulted in very little data, only 2 1/4 hours out of a possible 12 hours clear sky over 2 nights it was very frustrating.
So this is noisy and definitely a work in progress.

Lum 7 x 600secs
red 7 x 150secs binned
Green and Blue 5 x 150secs binned each
Probably doesn't need too close an inspection at this stage.
Nice , really well defined shark there, think its a Thresher,
Roger
Thanks Roger, had to look Thresher up, not heard of that one.
At least I managed to rescue the colour data but very odd.

You did very well for that little time in this object. It is faint and will take quite a few more hours to start showing detail above background noise. Keep at it! ;)
Roberto
Thanks Roberto, would not attempt it from Home, will wait until I next go to a dark site, which won';t be until end of September as I am on holiday for next DSC.

I spent almost 15hrs on this one a year ago: https://www.astrobin.com/full/367046/C/ I did it later in the year when nights were longer but still when it was culminating past midnight. I was pretty happy that the double star that sits at the back of the "shark's eye" showed the spectral colours proper measurements show.
Keep adding data to it anytime there's a clear night; eventually it will become much easier to process.
Roberto
Very good Carole
Now I see the shark!
Noel
Thanks Roberto, well now I have the Idas Hutech LP filter, I will give it a try from home.
Thanks Noel, you were there at the time and saw all the problems.
Carole
That's a really ghostly shark, very nice Carole.
Thanks Duncan, really needs a lot more data.
