The blinking planetary nebula is a dying star that is emitting waves of gas and solar wind. As the star burns out and nears the core, the solar wind increases in speed, exciting the slower material ejected earlier as it passes through. This creates an emission nebula around the star. These nebula are short-lived and burn out after a few thousand years.
The blinking PN gets it's name because the bright star in the middle obscures the faint nebula when viewed directly, but when viewed using averted vision the nebula magically appears!

The Orion Molecular Complex.
I originally wanted to just capture the Witch Head Nebula near Rigel (bottom right corner) but used the clear skies to try out a different astro imaging suite called NINA. It's pretty easy to use but I stuck with gold ol' APT to catch this short session.

North America Nebula 25-10-21.
The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico.

NGC 281, IC 11 or Sh2-184 is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm. This 20×30 arcmin sized nebulosity is also associated with open cluster IC 1590, several Bok globules and the multiple star, B 1. It collectively forms Sh2-184, spanning over a larger area of 40 arcmin. A recent distance from radio parallaxes of water masers at 22 GHz made during 2014 is estimated it lies 2.82±0.20 kpc. (9200 ly.) from us. Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.
Edward Emerson Barnard discovered the nebula in August 1883, describing it as "a large faint nebula, very diffuse." Multiple star 'B 1' or β 1 was later discovered by S. W. Burnham, whose bright component is identified as the highly luminous O6 spectral class star, HD 5005 or HIP 4121. It consists of an 8th-magnitude primary with four companions at distances between 1.4 and 15.7 arcsec. There has been no appreciable change in this quintuple system since the first measures were made in 1875.
SH2-103 The Cygnus Loop is a supernova remnant in the constellation Cygnus. The remains of a massive star which exploded as a supernova approx. 20000 years ago. It is about 2400 lightyears distant. The gasses, mostly Hydrogen and Oxygen form an expanding sphere which is ionised by ultraviolet starlight and glow in the colors of red and blue-green.

Caldwell C6 Cats Eye Nebula. Its my 1st time achieving some detail of this dso. I am on alt/az alignment and look forward to future attemps at improving the detail and colouration as skill and equipment improves. imaged with cpc925 60d at prime, iso100 10"exp.
Venus with M45 Pleiades. This is my first play with Deep Sky Stacker and this is 18 shots stacked with flats etc, this shot was one of the stack processed on it's own.

Not perfect but I do like the lack of noise in the shot.
M57, the aptly named "Ring nebula". This is a planetary nebula, which is to say that it is a dying star that is emitting various gases which generate all the colors. I looked for this a few times before when it was low in the sky but never saw it. This morning (early this morning!!!) it was high in the sky and easy to find. This was shot with the camera using the telescope as the lens. There are some tracking errors that I hope to iron out next time with PEC (and a little TLC!).
Here’s a first light with my William Optics Minicat 51. As with any new scope, persistent clouds arrived in the Northeast New England all of December, making imaging a challenge. I managed to capture just under 39 hours of data on NGC 7822, the “Cosmic Question Mark,” using Antlia 4.5nm SHO+rgb filters. Check out more of my Astrophotographs on Instagram or Astrobin. Happy New Year and Clear skies!

While "scouting" a location, I missed the comet (could see handle of big dipper slipping away under horizon) but there was this fantastic expanse of dark sky all around. The lens at 70mm was still too narrow to capture much of the milky way,.. but here it is, nonetheless.

It's been awhile since I've posted anything, for various reasons, but I'm excited to share my most recent area of interest, astrophotography. The work is much more challenging and time consuming, but the payoff is amazing.
This image is of the mighty Orion Nebula (M42), found in the constellation Orion. This northern-hemisphere wintertime favorite of visual and photographic astronomers is full of amazing colors and structures. This image was taken with narrowband filters in the Hydrogen-alpha (656 nm), Oxygen-iii (~500nm), and Sulfur-II (672nm) ranges, with those individual images recast into the red, green, and blue channels of a regular RGB image. Add a sprinkle of math to balance the colors, and you get this lovely false-color view of the nebula.
This was imaged under Bortle-8 class skies, with a full moon present and very close to the subject field of view, so there was quite a bit of interference during the imaging session, and I think it had at least a bit of an impact on the data, but I was able to get something usable none the less. Orion is so bright, such a rewarding target to shoot!

The Witch Head Nebula, also known by its official name, IC 2118, is a very faint reflection nebula in the constellation Eridanus. It was nicknamed the Witch Head because it looks like a profile of a wicked witch. The nebula is illuminated by the bright star Rigel in Orion.
It lies at a distance of 1,000 light years from Earth and has an apparent magnitude of 13. Its designation in the New General Catalogue is NGC 1909.
The Witch Head Nebula is an ancient supernova remnant or a gas cloud illuminated by the nearby blue supergiant Rigel, Beta Orionis, the brightest star in Orion constellation and the seventh brightest star in the sky. The nebula can be found to the upper right of the star, but it is not visible to the unaided eye.
Reflection nebulae reflect light from just one or several nearby stars. If the stars responsible for illuminating the dust clouds are hot enough, they ionize the gas, creating emission nebulae. This isn’t the case with IC 2118, as the nebula merely reflects Rigel‘s light.
IC 2118 is located 2.6 degrees to the west of Rigel. The star is approximately 860 light years distant from Earth and about 40 astronomical units away from the Witch Head Nebula. Rigel has an absolute magnitude of -7.92 and a luminosity about 120,000 times that of the Sun, which is how it is able to illuminate clouds lying at a distance 40 times that between the Earth and the Sun.
Radio observations of the nebula have revealed that parts of IC 2118 show significant carbon monoxide emission. This indicates that the nebula contains molecular clouds where star forming activity occurs.

Image of NGC 7331 taken in August and September 2022 from my backyard.
NGC 7331 is a galaxy about 40 million light-years away in the constellation Pegasus. It was discovered by William Herschel in 1784. It is the brightest galaxy in the field of a visual grouping known as the NGC 7331 Group of galaxies. The other members of the group, NGC 7335, 7336, 7337 and 7340, lie far in the background at distances of approximately 300-350 million light years.

The Cat’s Paw Nebula, also known as the Bear Claw Nebula, is an emission nebula in Scorpius. The nebula is about 50 light years across and lies at an approximate distance of 5,500 light years from Earth. It is one of the nearest H II regions to the solar system. It has the designation NGC 6334 in the New General Catalogue.
The large glowing cloud earned the nickname Cat’s Paw because it looks like a gigantic pawprint of a cat. The nebula is a popular target of study as a nearby example of a vast, very active stellar nursery.
NGC 6334 is a large star forming region, covering an area in the night sky slightly larger than the full Moon. It is one of the most active stellar nurseries producing massive stars in the Milky Way Galaxy. The hot young stars embedded in the nebula are responsible for its glow. The stars are each roughly 10 times as massive as the Sun and were formed relatively recently, within the last few million years.

Trifid Nebula M20
Discovered by Charles Messier in 1764, M20 is a star-forming nebula located 9,000 light-years away from Earth in the constellation Sagittarius. Also known as the Trifid Nebula, M20 has an apparent magnitude of 6.3 and can be spotted with a small telescope. It is best observed during August.
This eerie Hubble image features the center of the Trifid Nebula and the three wing-like bands of thick dust for which the nebula was named. A group of recently formed, massive, bright stars toward the center of the nebula is easily visible. These stars are releasing a flood of ultraviolet radiation that dramatically influences the structure and evolution of the surrounding nebula. Star formation is no longer occurring in the immediate vicinity of this group of bright stars because their intense radiation has blown away the gas and dust from which new stars are made.
The image’s stair-step appearance results from the design of the camera used to take the exposures. The camera consisted of four light detectors, one of which provided a higher resolution but had a smaller field of view than the other three. Because the detector with the higher resolution did not cover as much area as the others, black regions were left when the images from all four detectors were combined into one picture.
This Hubble image of M20 has been colorized to indicate the presence of oxygen, sulfur and hydrogen.

After months of cloudy nights, I decided to process terrestrial clouds as any other DeepSpaceObject from our Universe, to create a new one. I call this method Science Fiction Astro Imaging. I hope you find it interesting and it becomes an option for you too during cloudy nights.
Neither CGI nor Artificial Intelligence were used to achieve these images. What you see is up in the sky. See it through the vortex.

The Crab Nebula is the remnant of a supernova that was seen in 1054. This cloud of expanding gas is now about 8 light years across, and is about 6500 light years from Earth. This image was obtained using the Seestar S50 Smart Telescope. The sky was Bortle 7, with high humidity, haze and passing clouds. While collecting the hour of exposures, there was a Falcon 9 launch from Cape Canaveral Space Force Base, 90 miles to the east. The engine plumes from the first and second stages were clearly visible.
