My first go at Centaurus A. Conditions weren't ideal, especially since there were loads of moisture in the air and the cold didn't help much.

:bigshock: That's awesome! I looked at this one a few months ago, all I can see of it is a vague hint that something is there with averted vision.

KJ,

Impressive close in sketch. This target is a bit too low from my location. Someday when I am further south I'd like to have a go at this one. Excellent post! :waytogo: :bow: :rainbow:

Frank :)

KJ,

An impressive observation of one of the most interesting celestial objects visible in the heavens. Centaurus A (NGC 5128) is a very interesting lenticular (elliptical) galaxy in Centaurus that lies approximately 14 million light-years from the Earth. A supermassive back hole is believed to lie at the center of Centaurus A which produces an impressive relativistic jet detected at radio and x-ray wavelengths. I have seen this object from South Florida in large aperture instruments and it is very impressive in the eyepiece field. Thank you for sharing it with us all.

KJ,

Wonderful sketch! :bow:
This must be one of the showpieces from your sky, I guess.
Too bad its too low from my site.

Thanks for all the input guys. I'm sad to say that my sketch doesn't do it justice. It definitely is one of the showpieces in the Southern sky if you can manage to drag yourself away from Omega Centauri to observe it.

What is most surprising to me is that the dark dust lane appears to have very straight edges, at least it did to me at 150x in the 10".

Tremendous sketch KJ! :bow: :bow: :bow: The nebulosity and dark dust lane is wonderfully rendered in your beautiful sketch. Nice to see southern hemisphere sketches, so keep 'em coming!

KJ,
Great sketch of a very interesting object with an unusual appearance. I searched for it this spring when I took my annual look at Omega Centauri. Even though it is higher than OC, ~9 degrees above my horizon, I was unable to detect it with the 108mm reflector. I think I'll have to use more aperture next time. Meanwhile, thanks for the view. :)

You have a much better view of this radio galaxy than I do, which I can barely see with the haze and light pollution that lurks near the horizon. A very good rendition of this weird and active elliptical galaxy. Nice rendering of the dark lane that divides the disk in two.
