SNR G206.9+2.3, nestled within the celestial expanse of the Monoceros constellation, emerges as a captivating enigma in the cosmic tapestry. This supernova remnant (SNR), born from the explosive demise of a massive star, stands as a testament to the awe-inspiring forces that shape our universe.

Stretching across the vast reaches of space, SNR G206.9+2.3 bears the scars of its tumultuous birth, manifesting as a complex structure of shock waves, filaments, and expanding gas clouds. Within its luminous confines lie the remnants of the progenitor star's core, dispersed into the cosmos in a spectacular display of stellar cataclysm.

Image Description and Details : NGC 4631 (also known as the Whale Galaxy or Caldwell 32) is a barred spiral galaxy in the constellation Canes Venatici. This galaxy's slightly distorted wedge shape gives it the appearance of a herring or a whale, hence its nickname.Because this nearby galaxy is seen edge-on from Earth, professional astronomers observe this galaxy to better understand the gas and stars located outside the plane of the galaxy.

Image Description and Details : This image features many interesting celestial objects in Cygnus, the brightest star in that constellation. First and foremost, there are two Sharpless objects known as SH2-115 & SH2 116. The first one is a very large, faint emission nebula approximately 2 degrees northwest of Deneb. Its neighbor, SH2-116, is a small round planetary nebula, featured also in this image. Secondly, they are many LBN objects in the field of view – too much ! Let’s pause there for the time being….

Image Description and Details : The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy distanced 21 million light-years (six megaparsecs) away from Earth in the constellation Ursa Major. Discovered by Pierre Méchain on March 27, 1781, it was communicated to Charles Messier who verified its position for inclusion in the Messier Catalogue as one of its final entries.
M101 is a large galaxy, with a diameter of 170,000 light-years. By comparison, the Milky Way has a diameter of 100,000 light years. It has around a trillion stars, a little more than twice the number in the Milky Way. It has a disk mass on the order of 100 billion solar masses, along with a small central bulge of about 3 billion solar masses.
M101 has a high population of H II regions, many of which are very large and bright. H II regions usually accompany the enormous clouds of high density molecular hydrogen gas contracting under their own gravitational force where stars form. H II regions are ionized by large numbers of extremely bright and hot young stars; those in M101 are capable of creating hot super-bubbles.
M101 is asymmetrical due to the tidal forces from interactions with its companion galaxies. These gravitational interactions compress interstellar hydrogen gas, which then triggers strong ​star formation activity in M101's spiral arms that can be detected in ultraviolet images.

Description:
Far from home, under a dark and clear sky, I had to drive 3 hours from my light polluted city, "Jeddah" to capture one of the most gorgeous targets in the sky, the Leo Triplet Galaxies with the beautiful tail of NGC3628 Galaxy. I wasn't sure if the night would be cloudy or not, I wasn't sure if it was a safe place or not, but I just packed my rig and drove to the place. Fortunately, I found a nice shepherd living there so I stayed with him, the sky was crystal clear, and the place was safe. I was able to collect 6 hours of LRGB data until the cloud passed by. But, since the sky was too dark and clear, I was able to bring out a lot of nice and breathtaking details of this beautiful region of the sky. I believe it's my best deep sky capture to date. As we can see in the image, there are three main Galaxies which are M66, M65, and NGC3628 with its 300,000 light-years long tidal tail. These Galaxies are about 35 million light year away from Earth in the constellation Leo.

Image Description and Details : This is a region of space in Auriga showing a large and faint Supernova Remnant (Sh2-221) next an equally large and faint Planetary Nebula (Sh2-216). The latter is also often called the "Second Closest Planetary Nebula." The former may be an example of the earliest recorded supernova (~6600 years ago) as a cave drawing depicting this area of sky was found with a possible illustration of a bright light in the same area of sky, though this interpretation is not conclusive.

Altogether this field of view covers over a dozen times the apparent width of the Full Moon in our sky and was captured with a total of 44.5 hours across 9 nights of imaging (9 hours RGB, 36.5 hours evenly split between Hydrogen and Oxygen filters).

Image Description and Details : Two photos, two moments, the same place!
How about photographing the same location in completely different lighting angles?
The attached photos were taken 4 months apart and with the sun in exactly opposite positions. In the photo above we have the Sun to the east, rising in Plato and Valiis Alps, the photo below was taken with the Sun to the west, there the Sun is setting in the same region. Photos in these conditions and of such magnitude, sublimely show the differences that the Moon offers us at every moment and show us that one day will never be the same as the other.
Plato is one of the main targets of lunar astrophotography.
A good photo of Plato should show at least 3 or 4 smaller craters present on its floor, always in a darker hue than the surrounding terrain.
But every good self-respecting astrophotographer knows that it's not easy to make these small craters appear on your floor, and for that to happen certain conditions must be met.
Firstly, an opening of no less than 250mm is ideal, not that it is impossible to register them with 200mm or even 180mm, but with 250mm it is much easier.
Secondly, the angle of incidence of sunlight must also be observed, if the terminator is too low and close, the contrast is too great making it difficult to record, if on the other hand the sun is too high, the smaller craters do not form shadows which it also makes it impossible to register them. I believe that the ideal is the Sun at an altitude of 30° to 45° so the contrast is not so great and shadows are still formed, facilitating their perception.
Thirdly, we must pay attention to seeing, with a bad seeing any recording is almost impossible, as these small craters disappear when the turbulence is strong.
Focus I won't talk because any mistake ends with a good result!
As a general rule, in order to get an impressive photo of at least some of these small craters, they would have to be briefly visible during real-time computer screen capture. If so, we learned that after the best stacked frames, these small craters will show up perfectly as seen in the attached photo.
Vallis Alpes, in the south of Mare Frigoris, not far from Cassini crater and Plato's Great Eastern Plain, is one of the most spectacular valleys on the moon.
Seen in this image, Vallis Alpes (Alpine Valley) is a feature that extends 166 km from Mare Imbrium, running northeast to the edge of Mare Frigoris. This valley was discovered in 1727 by Francesco Bianchini. The valley is narrow at both ends and widens in the center to be about 10 kilometers in diameter.
The bottom of the valley has a flat, lava-flooded surface with a narrow 'channel' winding through the middle. This channel is generally thought of as a "graben", an area between two parallel faults that have fallen below the surrounding area. The narrow inner channel is believed to have formed after the formation of the Imbrium basin, after the lava flows into the sea. It probably corresponds to a 'lava tube' that collapsed in a later geological episode due to the high velocity and low viscosity of the magma.
It is very interesting to know that channels are common on the moon, considered one of the most fascinating volcanic features due to their wide range of scales (from 100 meters to over 100 km in length) and the morphologies they present (linear, curved or sinuous). .
Channels typically form when lava flows erode the existing surface, melting the substrate, removing mechanical material, or a combination of thermal and mechanical processes. However, some may have been lava tubes, rilles, that suffered roof collapse after their formation.
Trying to detect this relatively narrow and winding channel that runs along the bottom of Vallis Alpes is one of the favorite challenges of lunar observers, its exact dimensions have not been determined, but its vision is a very satisfactory test, as are the small craterlets on the Plato floor. .
I hope these tips are of some use to anyone like me who likes to venture into lunar photography!

PS: The bottom photo is just a result of stacking in AS!3 with a sharpness of 60% and nothing else. There is no post processing, Registax, Astrosurface, Photoshop or any other editing program was not used, nor was brightness or contrast adjusted. I've been developing a capture line on lunars for years to avoid any post processing as much as possible, I'm almost there.

NGC 2835 is an intermediate spiral galaxy located 35 million light years away in Hydra.

The galaxy spans around 65000 light years across which is around 1/2 the size of our galaxy. There are multiple twisting spiral arms which create the illusion of an eye at the center. Numerous bright blue regions indicate high levels of near ultraviolet light which are star forming regions.

The galaxy hosts a massive black hole at its center.

Image Description and Details : I can find no direct information about how far away these objects are, but from our perspective, they are just to the northwest of the Cone and Foxfur nebulas as well as the Christmas Tree cluster in Monoceros. The Cone nebula is about 2,700 light years away from us, but these objects could be much closer or much farther away.

The dark nebula, B39, resembles the shape of a feral hog to me, so I gave it that name. And the bright region, LBN902, reminds me of the larger Tulip nebula in Cygnus.
