Eta Carina Nebula is the southern hemisphere’s most prominent deep space object. In fact, this nebula is the reason why I packed all my portable astro-gear and flew to Namibia. Carina is approximately 4x brighter than the Orion nebula, which could be considered a highlight of the northern hemisphere. Moreover, it’s much larger. The nebula is a combination of emission and dark nebulae, located in the constellation Carina and it’s roughly 8500 light-years away from us.

It was a struggle to get the rig working in Namibia, but after two nights I managed and the next day, when I processed the pictures, a big smile appeared on my face. Well done, mission accomplished.

During our stay at Kiripotib Namibia, the other guest rented a 14.5-inch Dobsonian telescope and allowed us to have a look at the Carina (thank you so much, Peter). It was a simply spectacular view. Such a huge aperture combined with TeleVue eyepieces – WOW effect was there. Moreover, the Dobsonian had a filter wheel with OIII, UHC, and H-beta filters. Just by turning it, one could see a completely different nebulosity. I was really happy to see this beautiful deep space object with my own eyes.
