Messier 29 (M29) is an open cluster located in the constellation Cygnus, also known as the Northern Cross. Discovered by Charles Messier in 1764, M29 is a compact group of stars that can be observed through binoculars and small telescopes. Positioned approximately 4,000 light-years from Earth, this cluster spans about 11 light-years in diameter and contains around 50 stars. Its most prominent stars are young, hot, blue B-type giants, with the brightest being of spectral type B0, shining with a magnitude of around 8. These characteristics indicate that M29 is relatively young, with an estimated age of about 10 million years.
This image was taken on 26/6/2024 with the Meade 0.40 m LX200GPS telescope and QHY600M Pro CMOS camera by Isaac Laing (Physics UG at the University of Warwick). The image was created by stacking 10 images of 20s exposure into each of four filters, then assigning colors to each filter and stacking those.

M27, also known as the Dumbbell Nebula, is a prominent planetary nebula located in the constellation Vulpecula. Discovered by Charles Messier in 1764, it was the first planetary nebula to be identified. M27 is approximately 1,360 light-years away from Earth and spans about 2.5 light-years across. The nebula is the result of a dying star shedding its outer layers, creating a glowing shell of ionized gas illuminated by the central white dwarf. Its distinct dumbbell shape is due to the varying densities and structures of the ejected material.

M101, also known as the Pinwheel Galaxy, is a grand-design spiral galaxy located approximately 21 million light-years away in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 and later cataloged by Charles Messier. M101 is notable for its large size, with a diameter of about 170,000 light-years, making it nearly twice the size of the Milky Way. It exhibits a well-defined spiral structure with prominent arms rich in star-forming regions, containing numerous H II regions where new stars are born. The galaxy's asymmetrical appearance is likely due to gravitational interactions with neighboring galaxies.

M42, also known as the Orion Nebula, is a vast, diffuse nebula situated in the Milky Way, lying south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae visible to the naked eye and is located approximately 1,344 light-years from Earth. The nebula spans about 24 light-years across and is a prominent region of star formation, housing a young stellar cluster known as the Trapezium. M42's vibrant colors are primarily due to the ionization of hydrogen gas by ultraviolet light from the young, hot stars. The nebula's complex structure, including dense clouds of gas and dust, provides valuable insights into the processes of star birth and the dynamics of interstellar matter.

M13, also known as the Hercules Globular Cluster, is a prominent globular cluster located in the constellation Hercules. Discovered by Edmond Halley in 1714, M13 is one of the most impressive clusters visible in the northern hemisphere. It lies about 22,200 light-years from Earth and spans approximately 145 light-years in diameter. The cluster contains several hundred thousand stars, many of which are red giants and variable stars, packed densely into a relatively small region.The cluster provides valuable insights into the properties and evolution of stars, as well as the dynamics of star clusters.
This is a mosaic of 4 images taken on 07/07/23 with the CCD camera by Baidandri Saha (Physics UG at the University of Warwick). Each image of each filter is a stack of 5 images with 150s exposure.

NGC 6992 is part of the Veil Nebula, a large supernova remnant located in the constellation Cygnus. It is the eastern segment of this expansive nebula, also known as the Eastern Veil or the Network Nebula. It is the remnant of a massive star that exploded approximately 10,000 to 20,000 years ago. This nebula is characterized by its intricate, filamentous structure and vibrant colors, which are the result of ionized gases, primarily hydrogen, oxygen, and sulfur.

The Pelican Nebula, also known as IC 5070, is a striking emission nebula located about 1,800 light-years away in the constellation Cygnus. It forms part of a larger H II region complex along with its neighbor, the North America Nebula (NGC 7000). The nebula's distinctive shape, which resembles a pelican, is sculpted by intense ultraviolet radiation from nearby young, massive stars, which ionize the surrounding hydrogen gas, causing it to glow. This process also creates dark dust lanes and intricate structures within the nebula. The Pelican Nebula is a site of active star formation, where dense regions of gas and dust collapse under gravity to birth new stars.
This image was taken on 19/7/23 by Baidandri Saha. The BVRI filters were assigned colors of blue, green, red, and cyan respectively and each image is a stack of 5 - 150s exposure.

M51, also known as the Whirlpool Galaxy, is a grand-design spiral galaxy located in the constellation Canes Venatici, approximately 23 million light-years from Earth. It is one of the most well-studied and visually striking galaxies due to its distinctive spiral structure and interaction with its smaller companion galaxy, NGC 5195. This interaction has triggered intense star formation, particularly evident in the bright, well-defined spiral arms of M51. The galaxy spans about 76,000 light-years across and offers astronomers a vivid example of galaxy dynamics and evolution. Observations of M51 have provided critical insights into the processes of galactic interaction, star formation, and the nature of spiral galaxies.
