In the vast expanse of the Centaurus constellation, a celestial wonder awaits the gaze of astronomers and stargazers alike. NGC 5367, a mesmerizing reflection nebula, beckons us with its ethereal beauty and enigmatic allure. At the heart of NGC 5367 lies a stellar nursery, where new stars come to life. The nebula’s blue hues reflect the presence of young, hot stars, illuminating the surrounding gas and dust. NGC 5367, a reflection nebula in Centaurus, invites us to witness the cosmic artistry of light and dust. As we gaze upon this celestial wonder, we are reminded of the vastness and splendor of the universe, fueling our sense of wonder and exploration.

I had to dedicate a lot of imaging time to this deep-space object. Specifically, my camera was collecting 11 hours and 30 minutes, because all reflection nebulae need a lot of time to reveal all the details.

Leo triplet

Leo triplet is a group of galaxies in the constellation Leo. It contains galaxies NGC 3628 (upper left), Messier 65 (upper right), and Messier 66 (middle down). These galaxies are visible nicely in spring when the constellation Leo rises in the southern part of the sky.

I captured the picture shown here last year, but I haven’t had time to process it so far. It is interesting to compare the progress I made in astrophotography in the last few years. I made the very first picture of this group of galaxies in 2015 and for the first time, I used Pixinsight software for post-processing. The improvement over the freeware Deep Space Stacker was enormous. Similar boost I got recently when I installed BlurXterminator (Pixinsight plugin), which significantly improved the sharpness, but without any unrealistic artifacts.

M63 Sunflower galaxy

Messier 63 is a stunning spiral galaxy located about 37 million light-years away from Earth in the constellation Canes Venatici. The galaxy gets its name from the striking pattern of dust and gas that resembles the petals of a sunflower surrounding its bright yellow core.

The Sunflower Galaxy was first discovered by the French astronomer Pierre Méchain in 1779 and later added to the Messier catalog by Charles Messier in 1781. With an apparent magnitude of 8.6, it is easily visible with a small telescope or binoculars.

Spring is a great time to observe galaxies like Messier 63 because, during this season, the Earth is oriented in such a way that we are looking out towards the outer regions of our Milky Way galaxy. This means that the sky is darker and clearer, providing ideal conditions for observing distant galaxies.
