NGC 5139 drawing inverted into positive.

We were getting close to the end of our two weeks stay in Namibia when I realised that I didn't have a drawing of one of my main objectives the Omega Centauri. So I was quite in a hurry with the drawing and therefore it got be very inaccurate: I had to erase a considerable part of the starfield and shift it a little bit.

Omega Centauri itself is the biggest and brightest globular cluster in the sky. Or rather the remnanat of a galaxy that was engulfed by our Milky Way. It is indeed enormous and very bright. It is practically totally resolved with the little 4" tlescope even in the central regions. It has no core. The bright central part is circular while the faint outer regions are slightly enongated in the East-West direction. It looks like a spilled sack of poppy seed with its thousands of tiny faint stars. It doesn't have characteristic star chains.
