Yet another NGC 5128

It's obviously the season for this galaxy

NGC 5128 or Centaurus A is one of the closest radio galaxies to Earth at a distance of approximately 12 million light-years. It has a distinctive central dust lane and an active galactic nucleus containing a supermassive black hole creating a relativistic jet which emits in visual, radio and X-ray wavelengths. The inner and outer filaments of the optical jet are visible here as the red streaks between 2 and 3 o'clock. It is an unusual galaxy, possibly the result of a merger between an elliptical galaxy and a smaller spiral galaxy.

Scope: Planewave CDK17 @ f/6.8 = 2939mm FL
Mount: Paramount ME
Camera: SBIG STXL-11002/AOX
Filters: Astrodon LRGB gen II, 3nm NB
Image scale: 0.63 arcsec/pixel
Exposures: 15x1200s R, 15x1200s G, 15x1200s B, 22x1200s L, 11x1800s Ha (27.83 hours)
Processing: PixInsight 1.8.5

Fantastic data captured at Heaven's Mirror observatory by Martin Pugh, processed by yours truly.

Cheers,
Rick.

Superb shot!
PS: dithering + flat fielding should get rid of those two smears at 2 o'clock.

I've never seen this galaxy before. Intriguing beastie...



Stack 'em up like cord-wood

Great rendition of it, and nice processing.

A jolly good hamburger Rick. Nice capture of the optical jets.

* Edit: I've just looked at my own image of Centaurus A and there is no sign of the Ha jet and then realised of course that I only imaged in LRGB. We might just be going back in with the Ha filter to see what we can pick up. Thanks Rick.

Hi Rick,

Wow - that's one of the best I've ever seen.
The full resolution is amazing & those jets are so clear.
Nice to see an Ha filter used.
That should be an APOD.


cheers
Allan

Thanks for the helpful advice, Marc. It's probably a Camembert stain

Thanks, Rodney. You never know what you'll find with a few hours of NB!

Thanks, Peter. I like this long FL stuff. Will have to put a big Alluna on my wishlist.

Great image Rick. I think that deserves two bottles of FG champagne.

Cheers Rob

Outstanding image Rick

I also do not recall seeing the jet so clearly in any other image - and the scarce photons from the jet were captured with the old school “noisy n with apparently so-so QE” CCD

Thanks, Suavi. I probably should have mentioned that we binned x2 the Ha.

Nicely done Rick. I've never realised that the jet was there. Definitely something to aim for. Good idea binning the Ha--you're not really after a lot of detail.
