The Head of the Soul Nebula IC1871
This is a sectional view of the large star forming region called the Soul Nebula (Embryo Nebula, IC 1871, Sh2-199) and is found in the constellation Cassiopeia. This nebula is often shown next to the Heart Nebula (IC 1805). The Soul Nebula is about 6,500 light years away from Earth and contains several open clusters and few smaller emission nebulae around the perimeter. The star clusters are surrounded by hydrogen, which glows red from the young hot stars nearby. This view only shows about 1/3 of the entire nebula.

C/2022 E3 (ZTF) Observation
Here is a 60-minute combined exposure showing Comet C/2022 E3 (ZTF) in the early morning hours and moving through the constellation Bootes.
You can see the thin ion tails extending to the upper left, likely the result of a variable solar wind on ions ejected by the icy comet nucleus. The comet's white dust tail is visible to the left and much shorter. The green glow is the comet's coma, caused by glowing carbon gas. Comet ZTF is expected to pass nearest the Earth in early February, after which it should dim dramatically. (REF: https://apod.nasa.gov/apod/ap230109.html).
From EarthSky.org “Astronomers call this comet C/2022 E3 (ZTF). It got its name because it was the third such object to be discovered in the fifth half-month (A, B, C, D, E) of 2022. The ZTF stands for the Zwicky Transient Facility, which uses the 48-inch Samuel Oschin robotic telescope, located at Mt. Palomar in southern California.”

This is the Flaming Star Nebula (IC405) and the Tadpole Nebula (IC410). The Flaming Star Nebula is the coma-shaped nebula on the top, the Tadpole Nebula is the large, circular nebula near the bottom. From Wikipedia, IC405 is an emission and reflection nebula in the constellation Auriga, surrounding the bluish star AE Aurigae. It shines at magnitude +6.0. IC410 is a faint and dusty emission nebula of more than 100 light-years across approximately 12,000 light-years away from Earth in the northern constellation of Auriga. NGC 1893, an open cluster, is embedded inside IC410. High clouds filled the imaging area causing the fuzzy display.

The California Nebula - NGC1499 Through High Clouds
This is the California Nebula (NGC 1499 or Sharpless 220) an emission nebula in the constellation Perseus that I imaged back in September. This nebula is about 1,000 light years from the Earth. The nebula is being lit up by the star Menkib which is the brightest star in the image. During the imaging sessions high clouds passed overhead causing the fuzzy display shown.

The Ghost Nebula (Sh2-136)
The Ghost Nebula (Sh2-136)
The Ghost Nebula (designated Sharpless 2-136 (Sh2-136) is a rather isolated reflection nebula over 2 light-years across, located some 1200 light-years away at the edge of the Cepheus Flare molecular cloud complex in the constellation Cepheus. It is nicknamed the “Ghost Nebula” due its spooky appearance and to several human-like figures with arms raised, rising up from the top of the cloud structure to the left of the bright reflection. The complex process of star formation creates dust clouds of many shapes and sizes. In the case of the Ghost nebula, spooky shapes seem to haunt this starry expanse drifting through the night. Of course, these shapes are also cosmic dust clouds. Several stars are embedded in the nebula, and their light gives it a ghoulish brown color.
Also cataloged as Bok globule CB230, the core of the dark cloud on the right side of this image is collapsing and is likely a binary star system in the early stages of formation, identified as BD+67 1300. Bok globules are dark clouds of dense cosmic dust and gas within star-forming regions in which star formation usually takes place. They most commonly result in the formation of double or multiple star systems.
The name Sharpless comes from a catalog of 312 emission nebulae (H II regions). The first edition was published by Stewart Sharpless in 1953 with 142 objects (Sh1) and the second and final version was published in 1959 with 312 objects (Sh2).

Cygnus X-1 - Black Hole
While imaging and processing the The Tulip nebula, I was surprised to see I also captured the shock wave being produced from Cygnus X-1. It is the site of one of the first suspected black holes. Over the years the location of this X-ray source became more accurately determined. The X-ray source was found to lie very close to the position of a 9th magnitude star called HDE 226868. This star is a large blue supergiant, and its companion – the more compact of the two objects in the system – is thought to be between 20 and 35 solar masses. Since the largest possible mass of a neutron star can not exceed three solar masses, the compact object which is unseen, is almost certainly a black hole. These two objects share an orbital periodicity of 5.6 days.

Star-Forming Region Sh2-106
Star-Forming Region Sh2-106
Sharpless 2-106, Sh2-106 or S106 for short, lies nearly 2,000 light-years from us. The nebula measures several light-years in length. It appears in a relatively isolated region of the Milky Way galaxy. A massive, young star, IRS 4 (Infrared Source 4), is responsible for the furious activity we see in the nebula. Twin lobes of super-hot gas stretch outward from the central star. A ring of dust and gas orbiting the star acts like a belt, cinching the expanding nebula into an "hourglass" shape.
Detailed studies of the nebula have also uncovered several hundred brown dwarfs. At purely infrared wavelengths, more than 600 of these sub-stellar objects appear. These "failed" stars weigh less than a tenth of our Sun. Because of their low mass, they cannot produce sustained energy through nuclear fusion like our Sun does. They encompass the nebula in a small cluster. (Ref: https://hubblesite.org/contents/media/images/2011/38/2932-Image.html)

The Shrimp Nebula - Sh2-188
Sh2-188 is a planetary nebula in Cassiopeia. It does not have an official name but is often called the "Shrimp Nebula" or even the "Dolphin Nebula" due to its shape. The expanding gas from the planetary nebula is colliding with ambient gas in the interstellar medium. The nebula is nearly circular in shape but is much brighter to the southeast (lower right) because the central star is moving rapidly in that direction. Faint wisps of gas can also be seen in the opposite direction.

The Tulip Nebula (Sh2-101)
Sharpless 101 (Sh2-101) is a H II region emission nebula located in the constellation Cygnus. It is sometimes also called the Tulip Nebula because it appears to resemble the outline of a tulip when imaged photographically. It was cataloged by astronomer Stewart Sharpless in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years from Earth. Sh2-101, at least in the field seen from Earth, is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes. (Ref: https://en.wikipedia.org/wiki/Sh2-101)

NGC 6820 and NGC 6823
NGC 6820 and NGC 6823
NGC 6823 is an open cluster and is surrounded by an emission nebula designated as NGC 6820 (also known as SH2-86). This pair is located roughly 6,000 light-years away in the constellation Vulpecula.
The most striking feature is the trunk-like pillar of dust and gas protruding from the east side of the nebula towards the open cluster, NGC 6823 in the west. The center of the open cluster, which is about 50 light-years across, is about two million years old and is dominated in brightness by many young, bright blue stars, packed in a Trapezium-formed region of about 1.3 x 0.7 light-years across. Outer parts of the cluster, involving pillars of the emission nebula, contain even younger stars.
The huge pillars of gas and dust are probably formed when surrounding gas and dust is pushed and eroded away by stellar winds and radiation from the brightest cluster stars. Remarkable dark globules of gas and dust (Bok globules) are also visible in the nebula. Bok globules, named after the Dutch astronomer Bart Bok (1906-1983), who proposed their existence in the 1940′s, are dark clouds of dense cosmic dust and gas within star-forming regions in which usually star formation takes place. They most commonly result in the formation of double or multiple star systems. (Ref: http://annesastronomynews.com).

Merging Galaxies in Draco - Arp 81
Arp 81 is a strongly interacting pair of galaxies, seen about 100 million years after their closest approach. It consists of NGC 6621 and NGC 6622. NGC 6621 is the larger of the two, and is a very disturbed spiral galaxy. The encounter has pulled a long tail out of NGC 6621 that has now wrapped behind its body. The collision has also triggered extensive star formation between the two galaxies. Scientists believe that Arp 81 has a richer collection of young massive star clusters than the notable Antennae galaxies (which are much closer than Arp 81). The pair is located in the constellation of Draco, approximately 300 million light-years away from Earth. Arp 81 is the 81st galaxy in Arp's Atlas of Peculiar Galaxies.(Credit/Source: https://esahubble.org/images/heic0810bd/)

Bubble Nebula - NGC 7635
From Wikipedia: “NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is an H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.”

The Ghost of Cassiopeia - IC59 and IC63
The Ghost of Cassiopeia - IC59 and IC63
IC 59 and IC 63 are found in the constellation Cassiopeia very near the bright star Gamma Cassiopeia. This set of objects is also known as the Ghost of Cassiopeia. Gamma Cassiopeia also has the informal nickname of Navi. The “IC” designation comes from a group of objects discovered between 1888 and 1907, most made possible by photography, and known as the Index Catalogue.
These nebulae are a combination of emission and reflection, they are located about 610 light years from Earth and are about 10 light years across. Gamma Cassiopeia provides the radiation to light up this area of dust and gas, eventually dissipating in the area.

Here is a quick view of the star Deneb in the constellation Cygnus
From Wikipedia - Deneb is a first-magnitude star in the constellation of Cygnus, the swan. Deneb is one of the vertices of the asterism known as the Summer Triangle and the "head" of the Northern Cross. It is the brightest star in Cygnus and the 19th brightest star in the night sky, with an average apparent magnitude of +1.25. A blue-white supergiant, Deneb rivals Rigel as the most luminous first-magnitude star. However, its distance, and hence luminosity, is poorly known; its luminosity is somewhere between 55,000 and 196,000 times that of the Sun. Its Bayer designation is α Cygni, which is abbreviated to Alpha Cyg or α Cyg.

The Eastern Veil Nebula - NGC 6992 and 6995
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a large but relatively faint supernova remnant. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of explosion, the supernova would have appeared brighter than Venus in the sky, and visible in daytime. The remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full Moon). This is the Eastern Veil (also known as Caldwell 33), whose brightest area is NGC 6992, trailing off farther south into NGC 6995.

Comet C/2017 K2 Observation
Here is a 56-minute stacked image of Comet C/2017 K2 as it cruises through the constellation Ophiuchus in our southern skies. Check out the HUGE coma (cometary atmosphere) on this comet! Measurements suggest that the coma is nearly as large as the planet Jupiter.
From EarthSky.org “Astronomers first spotted this comet in 2017 using the Pan-STARRS survey instrument in Hawaii. At the time, they said it was the farthest active inbound comet they’d yet seen. It was between the orbits of Saturn and Uranus when they first saw it. Now it’s in the inner solar system, with closest approach to Earth on July 14. The comet will be closest to the sun several months later, on December 19, 2022. With a small telescope, you should be able to spot the comet throughout the summer.
According to in-the-sky.org, the current visual magnitude is listed as 8.81.

Spiral Galaxy Messier 94 (M94)
This is the spiral galaxy named Messier 94 (M94 or NGC 4736) found in the constellation Canes Venatici. It has an apparent magnitude of 8.99 and is about 16 million light-years away from Earth.
From NASA - New stars are forming at a high rate within the bright ring. This region is known as a starburst ring. The cause of this peculiarly shaped star-forming region is likely a pressure wave traveling outward from the galactic center, compressing the gas and dust in the outer regions. The compression of material means the gas starts to collapse into denser clouds. Inside these dense clouds, gravity pulls the gas and dust together until the temperature and pressure are high enough for stars to be born.

The biggest lesson was learning my all-sky dome camera tends to overheat the equipment inside, yikes, temperatures inside hit about 58C (136F). We had almost 600 people watching our live stream from all over the world and had a blast chatting through the event and sharing observations from your locations.

From Wikipedia, “A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers.”

NGC 772 (Arp 78) The Nautilus Galaxy
When I first imaged The Nautilus Galaxy (NGC 772/ARP 78) I was fascinated by its shape, one spiral arm stretched outward from the center. This is probably an effect of being tugged on by a satellite galaxy designated as NGC 770 (the bright fuzzy ball of light at the eight o'clock position). NGC 772 is also listed as ARP 78 in the Arp Atlas of Peculiar Galaxies. This catalog was compiled by Dr. Halton C. Arp and it details 338 peculiar galaxies. It is estimated that NGC 772 is twice the size of our Milky Way Galaxy! If you are looking at this image on Facebook or on our web site, I’ve also included an annotated version of the image.

I’ve imaged this galaxy three times in the last seven years, each time bringing out new details from changes in camera sensor technology, software processing and experience.
I’m not sure who first coined the name “Nautilus Galaxy”, but I did find a reference from 2008 by Ruben Kier who states, “I find the shape of NGC 772 resembles the nautilus shell, as illustrated to the right, so I have called it the Nautilus Galaxy.” (REF: http://www.stardoctor.org/772.html) If you Google “Nautilus Shell” you’ll see what he is talking about.

Here is a quick view of a new supernova located in the galaxy NGC4647 and discovered by Koichi Itagaki on April 16, 2022. At the time of imaging it was at magnitude 12.6. The comparison image on the top was taken using my 12” Meade LX-90 back in 2020. The large elliptical galaxy next to NGC4647 is Messier 60 (M60), they form a pair known as ARP116 and are interacting with each other.

Galaxy IC356 (Arp213) in Camelopardalis
Galaxy IC356 (Arp213) in Camelopardalis
IC 365, also known as Arp 213, is a spiral galaxy located in the constellation Camelopardalis (the Camel). The galaxy appears red in color, because it is situated behind the dust of the Milky Way, at a distance of approximately 50 million lightyears. If you look close you can make out some of the dark dust lanes in the spiral arms. Arp included this galaxy in his list of peculiar galaxies because of the odd dark lane that goes from the central region of the galaxy and extends to the 10 o’clock position in my image.

Here is a quick shot of the supernova, designated as SN2022ewj in the galaxy NGC 3367. It is a Type II supernova that can be found in the constellation Leo.
INFO: A Type II supernova (plural: supernovae or supernovas) results from the rapid collapse and violent explosion of a massive star. A star must have at least 8 times, but no more than 40 to 50 times, the mass of the Sun (M☉) to undergo this type of explosion. Type II supernovae are distinguished from other types of supernovae by the presence of hydrogen in their spectra. (Wikipedia).

Planetary Nebula NGC 40
Planetary Nebula NGC 40
From Wikipedia: NGC 40 (also known as the Bow-Tie Nebula and Caldwell 2) is a planetary nebula discovered by William Herschel on November 25, 1788, and is composed of hot gas around a dying star. The star has ejected its outer layer which has left behind a smaller, hot star with a temperature on the surface of about 50,000 degrees Celsius. Radiation from the star causes the shed outer layer to heat to about 10,000 degrees Celsius, and is about one light-year across. About 30,000 years from now, scientists theorize that NGC 40 will fade away, leaving only a white dwarf star approximately the size of Earth.

Starburst Galaxy NGC1569
NGC 1569 (also known as UGC 3056 and Arp 210) is a dwarf irregular starburst galaxy nearly 11 million light-years away in the constellation Camelopardalis. NGC 1569 is a hotbed of vigorous star birth activity which blows huge bubbles and super-bubbles. The galaxy’s vigorous “star factories” are also manufacturing brilliant blue star clusters. This galaxy is exceptional in that its spectrum is blueshifted. This means that the galaxy is moving towards the Earth. In contrast, the spectra of most other galaxies are redshifted because of the expansion of the universe. (http://annesastronomynews.com/photo-gallery-ii/galaxies-clusters/ngc-1569)

Planetary Nebula NGC 1501 in Camelopardalis
Planetary Nebula NGC 1501 in Camelopardalis
NGC 1501 lies in the constellation Camelopardalis (the Giraffe) and is roughly 5,000 light-years away. The internal complexity of this nebula is only hinted at in my image, you can see the various light and dark bands inside. It has also been referred to as the Oyster Nebula, from the bright central star peeking out of the cloudy shell around it. The surrounding cloud was formed when the central star blasted off its outer shells.

Observation of Comet C/2019 L3 (Atlas)
Here is a 60-minute combined image of the comet designated as C/2019 L3 (Atlas) as it is heading through the constellation Gemini. The comet is just past perihelion (closest approach to the sun) and heading back out into space. The comet was discovered as an asteroidal object by the Asteroid Terrestrial-Impact Last Alert System (ATLAS). The discovery image on 10 June 2019 showed it as an 18th magnitude, apparently starlike, object moving very slowly in the constellation Lacerta.
