NGC 5128 and supernova

[DiscoDuck]

Had a go at Centaurus A last night to see if the recent supernova was visible.

14 x 20 minute images with a QHY8 on a GSO RC8. The supernova is visible when viewed at 100%
(see full size version on Astrobin (http://www.astrobin.com/full/238897/0/?real=&mod=)) as a small red bump on the bright star in the top left of the central dust lanes.

I presume less aggressive processing would bring it out better?? i.e. rather than focussing on bringing out details in the dust lanes, etc :shrug:

Great detail Paul!

Really crisp.

Cheers,

Paul, that's a great shot even without the supernova. Nicely processed too.

The supernova is obvious, but in my ignorance I'm surprised at how faint it is. Only ever photographed two others. They were brilliant blue and outshone the host galaxy. Perhaps this one is partially obscured by dust, which would account for both the low brightness and the redness. Just making it up.

Best,
Mike

[astroron]

Mike you are correct on both counts.:)
Just think of the colour of the Sun at Sunrise and Sunset, it is reddened by dust and aerosol's in our atmosphere.

oh my mate do not be disappointed, that is a cracking centaurus A!

Finally managed a visual observation of this last night. Barry cranked up his 28" to about 1250x and it was visible, and at 650x in the 25" I was able to get it during the steady seeing in between wind gusts.
Very tough, and only possible because we knew where to look. No way would a visual search have nailed this one.
Cheers,
Andrew.

Great stuff Andrew..1250X in a 28" huh? :eyepop: (yud wanna have Servo Cat to do that!) and lovely capture of it Paul :thumbsup:

Yep - despite initial reports to the contrary, that Kennedy mirror in Barry's scope is a gem! And he's got the 32k encoders, servo cat and Argo tuned to perfection.
Cheers,
Andrew.

That is a really nice image Paul. Thanks for presenting.

Excellent!
Nothing ever stays the same, hey!

Thanks all for your comments.



:) It sounds convincing, Mike! Yes, only ever taken one image before with a supernova, when I was first getting into imaging a few years back, and that was a really bright star even with the host galaxy just a fuzzy faint blob. Not sure if the type of supernova's been settled yet with this one either. Presumably that dust has been hampering classification too.



Wow! My 14" dob suddenly seems very inadequate!:(
