NGC 104, also known as 47 Tucanae, is a massive globular cluster located in the constellation Tucana, about 13,000 light-years from Earth. It’s one of the brightest and most massive globular clusters in the Milky Way, containing several million stars densely packed within a roughly spherical shape. With a diameter of around 120 light-years, NGC 104 is easily visible to the naked eye in the southern hemisphere. The cluster is rich in older stars, giving it a golden hue, and is known for its dense core, where stars are packed thousands of times closer together than in our solar neighborhood.

M78 Nebula

The M78 Nebula, also known as Messier 78, is a bright reflection nebula located in the constellation Orion, about 1,350 light-years from Earth. Known for its striking blue color, M78 is illuminated by the light of young, hot stars embedded within it. The nebula’s dust particles reflect this starlight, creating a luminous glow that highlights its wispy clouds and dark lanes of dust. M78 is one of the brightest reflection nebulae in the sky and is a fascinating region of active star formation, where new stars continue to emerge within dense pockets of gas and dust.

Moon – Waxing Crescent

After long period of bad weather, I had the opportunity to take the telescope out and enjoy the clear skies. In the early evening, waxing crescent was setting down, so I took the opportunity and pointed my newton on the Moon. The illumination was only 34%, which means that as soon it gets dark, the Moon is not far from horizon and you have to capture it through thick layer of turbulent atmosphere. The picture is a stack of 700 frames.
