Messier 1 is a supernova remnant located in Taurus. In 1054, Chinese astronomers recorded a bright new star that faded away over time. For awhile it was the 2nd brightest object in the night sky after the Moon shining at a magnitude of -7. Venus on occasions will only make it to around -4,8 magnitude. Independently discovered by Charles Messier while looking for Halley's Comet, it gave him the ideal to record non-moving objects that could be mistaken for comets. It is also called the Crab Nebula because of a drawing William Parsons made that he thought it resembled a crab.
At the heart of the nebula is a pulsar, which is the remains of the progenitor star that collapsed down to a neutron star. The highly magnetized star is spinning around 30 times a second that creates the pulses of radiation. The progenitor star was thought to be between 9 and 11 solar masses, the existing star is around 1.4 to 2 solar masses and is compressed down to a size less that 30 kilometers across.

The Orion Nebula or M42 is one of the brightest nebulae in the sky, visible as a "fuzzy" star in Orion's sword hanging from the belt. The Trapezium cluster named for the four brightest OB stars form a trapezoid figure ionizes and illuminates the nebula. The nebula contains hundreds of young stars and more than 700 stars associated with the cluster.

Sometimes called the Oyster Nebula, NGC 1501 is a planetary nebula located in Camelopardalis (The Giraffe). The central star shed its outer layers and those layers are now illuminated by the central star. The central star is also reported to be a pulsating variable star with an extremely short period of brightness changes.

The Bubble Nebula or NGC 7635 is an hydrogen emission nebula with a bubble structure that is formed by stellar wind from a massive central star. Also in the field of view is the open cluster of Messier 52. M 52 is at a distance of 4,600 light years and the Bubble Nebula is a more distant 7,000 to 11,000 light years away.

NGC6992, or Eastern Veil Nebula, is the eastern part of a supernova remnant of a star that went supernova about 8,000 years ago. The whole object is around the diameter of 6 full Moons. Shock waves create the delicate looking structures as they encounter interstellar gas and dust.

Messier 57 is a planetary nebula located in the constellation of Lyra. Often referred to as the Ring nebula as it resembles a small ring visually in a telescope. A planetary nebula is formed when a star in the latter stages of its life swells up into a red giant phase and the outer layers are expelled into the surrounding space as the star contracts down to a white dwarf. The ionizing radiation causes the surrounding gas to fluoresce.
Independently discovered by Charles Messier and Antoine Darquier de Pellepoix in January 1779.
Imaged with the ES127 refractor and the Atik314L+ mono camera.
Also visible in this highly stretched version are several background galaxies.
