NGC 7023 Iris Nebula

NGC 7023 is a refection nebula, blue light from central hot young star SAO 19158 reflects off the dust grains illuminating the nebula. The nebula spans some 6 light years across. Spent some 33 hours imaging this object over August and September 2019.

NGC 2261 - Hubble's Variable Nebula 2019

NGC 2261 - Hubble's Variable Nebula. Patterns in the nebula vary over time probably due to dust clouds that cover the star R Monocerotis at the tip are casting shadows on the illuminated nebula. Located in the constellation of Monoceros. It is at a distance of 2,500 light years away. The star R Monocerotis is a T Tauri type of variable star which is an young star that hasn't yet entered the main sequence for stars. Imaged over several nights with an Explore Scientific 127 mm refractor and Atik 314l+ mono ccd camera using Clear, Red, Green, and Blue filters.

The Flame and the Horse

NGC 2024 - Flame Nebula, Barnard 33 - Horse Head Nebula, and the bright star Alnitak that ionizes the Flame causing it to glow. Thicker patches of dust and gas in front of the nebula shows up as the dark patches. The center of the nebula contains a cluster of stars, many newly formed.

The Horse Head Nebula is a dark nebula that lies in front of an area of ionized hydrogen gas that is energized by the star Sigma Orionis. It also is a stellar nursery containing newly and currently forming stars.

Both are part of the Orion Molecular Cloud.

Cropped version as the bright stars in that area causes nice rainbow patterns in my camera. 80mm refractor and Asi071 camera.

M 1

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.

Orion Nebula and Surrounding Area

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.

NGC 2244, M52 The Bubble and the Open Cluster

he 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.

NGC 6992 Eastern Veil Nebula

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. 

Imaged with 80mm scope and HaRGB filters

M 17

Messier 17 or often called the Omega nebula or Swan nebula due to its appereance visually in a telescope. A massive nebula and star forming region located in the constellation of Sagittarius with the dense cluster of stars of the Milky Way Galaxy in the background. The nebula spans some 15 light years in diameter and lies at a distance of some 5000+ light years. It is simular to the more famous Orion nebula.

The object was imaged using red, green, and blue filters with a Ha filter added to the red channel to highlight the nebulosity of the region. Imaged with the 80 mm refractor and using a mono Zwo1600 camera.

M 20, M 8 - The Trifid and Lagoon Nebulae

The Trifid Nebula (M20) and the Lagoon Nebula (M8) against the backdrop of the summer Milky Way Galaxy. The Trifid is a combination of an emission nebula, the reddish glow, a dark nebula, the dark areas in the nebula and a reflection nebula, the blueish area. The red emission is caused by hot massive stars in the nebula ionizing the surrounding cloud causing it to glow. The dark areas are thicker concentrations of the nebula that block light from behind it. The blue parts is caused by light from the hot massive blueish stars reflecting off of the dust grains.

The Lagoon nebula is primary an emission nebula but it has thicker concentrations of material in it. The small dark ones are referred to as Bok globules which are collapsing areas of the nebula. Both nebulae contain new and protostars forming out of the surrounding regions.

Imaged with the ED80cft and Zwo 1600 mono camera using R/G/B filters.

M 16, The Eagle Nebula (2019)

Messier 16, or often called the Eagle Nebula from the shape of the nebula, or Star Queen Nebula, from the shape of the pillars. The nebula is a star forming region in the constellation of Serpens. The bright cluster of O type stars seen in the right side of the nebula (NGC 6611) are responsible for illuminating the nebula.

The most famous part of the nebula, made famous by a Hubble image is the central spires in the nebula nicknamed the "pillars of creation". The hot white stars of NGC 6611 are gradually the dust structures in the nebula creating the spires. The spires are also locations of new stars being born in the clouds of dust, hence the name. The tallest pillar is approximately 4 light years in length. The entire nebula is located at a distance of 7,000 light years.

Imaged with the ES127 refractor, and Atik 314l+ ccd camera Ha, R/G/B filters with the Ha signal mixed into the red channel to highlight the nebula.
