Sun with Herschelprism

Doing astrophotography, i make photos of millions of stars, but the most important one is always missing. This was the reason to purchase a herschelprism. After 1,5 months of clouds i finally wanted to test it for the first time.

Emission Nebulae (H II)

An emission nebula is a nebula formed of ionized gases that emit light of various wavelengths. The most common source of ionization is high-energy […] emitted from a nearby hot star. Among the several different types of emission nebulae are H II regions, in which star formation is taking place and young, massive stars are […]

Globular Clusters

A globular cluster is a spheroidal conglomeration of stars. Globular clusters are bound together by gravity, with a higher concentration of stars towards their centers. They can contain anywhere from tens of thousands to many millions of member stars. Their name is derived from Latin globulus (small sphere). [1] Globular cluster – Wikipedia 22/10/06[↩]

Open Clusters

An open cluster is a type of star cluster made of up to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age. More than 1,100 open clusters have been discovered within the Milky Way galaxy, and many more are thought to exist. [1] https://en.wikipedia.org/wiki/Open_cluster 22/10/06[↩]

Galaxies

A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. […] Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a hundred million stars, to the largest galaxies known – supergiants with one hundred trillion stars, each orbiting its galaxy’s center of […]

Reflection Nebulae

In astronomy, reflection nebula are clouds of interstellar dust which might reflect the light of a nearby star or stars. The energy from the nearby stars is insufficient to ionize the gas of the nebula to create an emission nebula, but is enough to give sufficient scattering to make the dust visible. [1] Reflection nebula […]
