Here's an interesting juxtaposition between the dwarf planet Ceres, a relatively nearby object in the Solar System, passing in front of M100, a large spiral galaxy much much farther away. It took light 52 million years to travel to us from M100, which looks much like our own Milky Way galaxy. Ceres is the bright streak to the left of the galaxy, showing its motion relative to the background sky over 2 hours of exposures. It is currently at its brightest (about mag. 7), located opposite the sun from our point of view. Other galaxies also appear in the image, some about the same distance as M100 but smaller, others farther away.
Ceres was the first of the asteroids discovered, identified in 1801, now also known to be the largest body in the Solar System other than the planets, and now classified as a dwarf planet (along with the much more distant Pluto).
M100 has some distinction as one of the largest members of the Virgo Cluster of galaxies, though located in the constellation Coma Bernices. It also happens to have been one of the first targets for the Hubble Space Telescope after the first servicing mission in 1993, in which astronauts made repairs to correct the flaw in the primary optics. Those images clearly demonstrated the success of that mission and the promise of Hubble's many groundbreaking discoveries over its 33 years of operation -- and still going strong.

This image of the Veil Nebula was taken exclusively from my backyard under suburban light pollution using my radiantelescopes triad Ultra filter. .
The Veil Nebula - also known as the Filament nebula- consists remnants of a supernova. Its name is derived from its delicate, draped filamentary structures. The entire nebula is 110 light-years across, covering six full moons on the sky as seen from Earth, and resides about 2,100 light-years away in the constellation Cygnus, the Swan. wisps of gas, which are all that remain of what was once a star 20 times more massive than our sun.
The fast-moving blast wave from the ancient explosion is plowing into a wall of cool, denser interstellar gas, emitting light. The nebula lies along the edge of a large bubble of low-density gas that was blown into space by the dying star prior to its self-detonation. (NASA) #astromaniacmag

One of the objects I was able to photograph last night with some unusually clear sky after many cloudy nights, despite it being quite near the horizon. This is one of the more colorful regions of the Milky Way, called the Rho Ophiuchi nebula after the bright star within the blue cloud near the top. The brighter red star near the bottom is the brightest star in the constellation Scorpius called Antares, the Heart of the Scorpion. Much of the region is filled with dust, reflecting the light of nearby stars as well as some gas, mostly hydrogen, glowing because it's energized by the nearby hot stars.

Oberon and Titania can be imaged with a small telescope, Ariel, Umbriel and Miranda are closer to Uranus and are lost in the Bright glare in these images. I used 3x120 seconds for each image made with 24 hrs interval. The"Moons of Uranus" observing tool shows the relative positions of the Moons. The movement of Uranus relative to the background stars is also obvious.

The Veil nebula consists of different parts, each with their own designation. The best known ones are NGC6960, or the Eastern Veil Nebula, and NGC6992/NGC6995, or the Western Veil Nebula.
"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 supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun, and it exploded between 10,000 and 20,000 years ago. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon)."

This was a challenge as the stars in my first Ha were terrible due to slop in my image train (an extension wasn't flush with the focuser) so I shot 30 mins of Ha and then stacked that with the S2 and O3 before using Starnet+ to extract the stars. I then used Starnet+ to remove the stars from the main filters before stacking and processing them. I finally re-added the good starfield using PixelMath.
Overall, it is still lacking but this is mainly due to lack of overall integration but I'm pleased with it for a total of 5 hours. Used the Hubble SHO pallette for integration

Here's another supernova, this time in the spiral galaxy NGC 3147 a whopping 130 million light-years from us. Similar to the one in my previous photo, this one, SN 2021hpr, is also Type Ia, a "standard candle" some 5 billion times as bright as the Sun, which is why we can see it so far away. Kinda boring photo but pretty cool phenomenon.
Looks like the brightness currently is at about magnitude 15, by comparing to the known brightness of other stars in the frame. Several other galaxies are also in the image, though most are very faint and don't appear in the most familiar catalogs (Messier, NGC, IC) except for one: UGC 5570. Also a couple of stars in our Galaxy are bright enough to be in the HD catalog of bright stars.
This galaxy also hosted several other supernovae recently, the latest just this year, but that one has become much fainter than what I'm able to photograph. The usual frequency of supernovae in most galaxies is more like one every 100 years or so, so it's pretty unusual to get so many. Our Milky Way Galaxy is way overdue for a supernova though, by several hundred years, so keep watching the sky!37 exposures, 4 minutes each (108 min. total), ZWO ASI294MC Pro camera (cooled to -15ºC, gain 150, dark, flat, dark flat frames), Nikon 80-200mm f/2.8 lens @200mm, iOptron CEM25P drive, ASIAir controller, processed with AstroPixelProcessor, Lightroom and Photoshop.

The Leo Triplet in the constellation Leo...lol
The Leo Triplet is an interesting cluster of 3 gravitationally interacting galaxies in the constellation Leo. It is essentially part of the large Virgo Galaxy Cluster separated by just the artificial construct of constellation boundaries.
The triplet is comprised of M66 (NGC3627 - lower left); M65 (NGC3623 - lower right); and NGC3628 (top) it is also listed in the Arp catalogue of peculiar interacting galaxies as Arp.317.
At approx. 35 million light years away the 3 galaxies are gravitationally influencing each other. Suggestive evidence of this perhaps can be seen in the deformation of the outer spiral in the upper galaxy (NGC3628). (lower right edge).
The gorgeous star in the lower right is η Leonis. It is an orange-red giant almost 24 times the size of our sun. It has a very close companion star, making it a binary or true double star. The two stars are very close to each other giving them a short 8 year orbital period. (the image does not resolve the binary, and it appears as one star)
The total exposure integration is 129 minutes of LHaRGB composition at 540mm with an ASI2600MM Pro camera cooled to -5ºC.

The Pinwheel Galaxy, also known as Messier 101 (M101), is one of the best known spiral galaxies in the night sky.
M101 is a grand design spiral galaxy (a spiral galaxy with prominent and well-defined spiral arms) located in the constellation Ursa Major, the Great Bear. It is about 170,000 light years in diameter, which makes it roughly 70 percent larger than our galaxy, the Milky Way.
It is approximately 20.9 million light years distant from Earth, which means that we are seeing it as it was about 20.9 million years ago.

The bright star in the lower right of the image is Sadr (gamma Cygni). Sadr is the center star of the Northern Cross, a very recognizable asterism in the constellation Cygnus (the Swan). Although it appears to be "surrounded" by IC1318, the Gamma Cygnus Nebula, Sadr, at ~750LY, lies only about 1/8 to 1/4 of the distance to the nebula. The nebula is roughly 2000 to 5000 light years from our sun, but is still in our local region of the Milky Way.
