NGC 5139 Omega Centauri

NGC 5139 Omega Centauri is the biggest globular cluster in Milky Way. Even though this cluster is approximately 17 thousand light-years away from Earth, it can be seen even by unaided eyes. This is because it contains roughly 10 million stars. I managed to see this cluster in a very dark place in Namibia and I must say, it’s brighter than any other object in the sky.

IC 2944 Running Chicken Nebula

IC 2944 Running Chicken Nebula is an H II region located in the constellation Centaurus. It’s a galactic neighbor of the Carina Nebula because they both belong to the Sagittarius spiral arm of the Milky Way Galaxy. I must admit that this was my secondary nebula target for my trip to Namibia. Therefore, I didn’t dedicate much time – only 3 hours. However, the details popped out, so overall, I am happy with this “fake” Hubble palette picture.

And here is an even more “fake” picture, where the stars are completely removed. However, the nebulosity gained a 3D-like look.

NGC 5128 Centaurus A Galaxy

NGC 5128 Centaurus A is a galaxy, which can be found in cancellation, you can guess which one, Centarus. This galaxy is not visible from Europe or from the northern hemisphere. If anyone wants to observe or photograph it, has to go south. And this is exactly what I did. I went to Namibia, specifically to an Astrofarm Kiripotib. I went there with a plan and this Galaxy was my first and primary target. As for most galaxies, one needs a long focal length. Therefore, I rented a telescope there. Specifically, it was Meade 10″. I brought my own focal reducer TS 0.67 and attached my old ASI071. I made in total 133 pictures, each 3 minutes long, and stacked them together. This means nearly 7 hours of exposure time. The dust cloud blocking the light from the galaxy really popped out with a slight help of deconvolution.
