Comets are fascinating celestial bodies that are excellent subjects for astrophotography. These "tail stars" consist of ice, dust, and loose rock. I focus on the brighter comets near earth ...

Emission nebulae are fascinating – mostly red – objects for astrophotographers. These interstellar gas clouds shine on their own, stimulated by the energetic UV radiation of nearby hot stars ...

Open star clusters are beautiful astronomical objects that are excellent for astrophotography. These clusters of stars consist of a few dozen to thousands of stars. My focus is on the Melotte Catalogue, but I also select additional objects ...

Globular clusters are fascinating objects for astrophotography, characterized by their dense collection of thousands or even millions of ancient stars. My focus is on objects from the Melotte Catalogue, though I do not limit myself to it ...

Galaxies are fantastic deep-sky objects for astrophotography. They offer a wide variety of shapes and structures. I do not limit myself exclusively to the Caldwell and Messier catalogs ...

Reflection nebulae are interstellar clouds of gas and dust that reflect the light of nearby stars, making them visible. Most objects in this category are part of the van den Bergh catalog ...

Planetary nebulae are glowing shells of gas and dust that are formed when a low-mass star reaches the end of its life and runs out of fuel to sustain nuclear fusion in its core. As the star's core contracts and heats up, the outer layers of the star expand and are ejected into space, forming a glowing shell of gas and dust around the dying star. Despite their name, planetary nebulae have nothing to do ...

A supernova is an extremely bright and energetic explosion of a massive star. It marks the end of the life cycle of a star that must be at least about 1.4 times the mass of our Sun. The brightness of a supernova can, for a brief period, be as great as the entire galaxy in which it resides. During this short time, supernovae can emit more light than billions of normal stars. They are also ...

Dark nebulae are dense clouds of interstellar gas and dust that block the light of stars or glowing nebulae behind them. They appear in the sky as dark, silhouette-like regions set against brighter backgrounds. Astronomically, dark nebulae are primarily composed of cold molecular hydrogen and dust particles. While the dust accounts for only about one percent of their mass, it is responsible for the obstruction of light. The temperatures in dark nebulae are extremely low, ...
