This has been the biggest (and most pleasurable) challenge of all. Make a mosaic using a narrow band from a wide region of the sky. It was almost two months using every good day to capture.
The biggest difficulty was being able to make the correct color adjustment of the background of the image without affecting the nebulae, I lost count of how many times I used DBE on Pix or redid the mosaic by the APP until I managed to reach this final…

17 million light years from us, in the Constellation of the Chioma of Berenice we find a bright and beautiful galaxy marked by the initials M64.
It is also called "Black Eye Galaxy" due to a vast area of dark dust that covers part of the central area.
The latest studies have shown that the peripheral part of the Galaxy rotates in the opposite direction of the nucleus, probably due to an "ancient" clash with a smaller galaxy captured by M64. This clash would have started to rotate the outer part of the galaxy in the opposite direction to the nucleus. These two areas that rotate in the opposite direction collide forming compressed "gas pockets" creating regions with an extremely intense star formation.

Messier 95, also known as M95 or NGC 3351, is a barred spiral galaxy located about 33 million light-years away in the zodiac constellation Leo. It was discovered by Pierre Méchain in 1781, and cataloged by fellow French astronomer Charles Messier four days later. It has around 40 billion stars.

Reflection nebula NGC 1999 in Orion. The small bluish patch of nebulosity with an inverted T at its center is enveloped within a much larger area of emission nebulosity in Orion. The nebula is illuminated by the variable star V380 Orionis which is visible right nest to the dark inverted T. This dark are is a source of much discussion and has been images by many of the great observatories.

NGC 3576 is a minor nebula in the Sagittarius arm of the galaxy a few thousand light-years away from the Eta Carinae nebula. This nebula even received six different classification numbers. Currently, astronomers call the entire nebula NGC 3576. A popular nickname is "The Statue of Liberty Nebula" because of the distinctive shape in the middle of the nebula. The name was first suggested in 2009 by Dr. Steve Mazlin, a member of Star Shadows Remote Observatory (SSRO).

The more northern tribes of the northeastern United States knew this as the Crow Moon, when the cawing of crows signaled the end of winter, explains NASA, on its website. Other northern names were the Crust Moon, because the snow cover becomes crusted from thawing by day and freezing by night, or the Sap (or Sugar) Moon as this is the time for tapping maple trees.

NGC 6188 is an emission nebula located about 4,000 light years away in the constellation Ara. The bright open cluster NGC 6193, visible to the naked eye, is responsible for a region of reflection nebulosity within NGC 6188. NGC 6188 is a star forming nebula, and is sculpted by the massive, young stars that have recently formed there – some are only a few million years old. This spark of formation was probably caused when the last batch of stars went supernova.

IC 405 (Caldwell31) is a diffuse nebula visible in the constellation of Auriga, located at 1630 light years from Earth. In its direction you can see AE Aurigae, a variable and mysterious star, according to some studies it would be a star born in the region of the Orion Nebula about 2.7 million years ago and then moved to the Milky Way from there.

IC 405 shines with the radiation received from AE Aurigae, which ionizes its gases (mainly hydrogen) and gives it a red color; the blue patches are instead due to the reflection of the blue light of the star on the dark dust. IC 405 appears to be connected with other nebulosity systems, in particular with IC 410, visible one degree to the southeast; in reality they are much more distant objects.

IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a Galactic supernova remnant (SNR) in the constellation Gemini. On the plan of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth.
IC 443 may be the remains of a supernova that occurred 3,000 - 30,000 years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

Kronberger 63 is a planetary nebula in the constellation of Orion . It was discovered by Austrian Mattias Kronberger who is a member of the amateur group Deep Sky Hunters.

It is very faint and thus rarely imaged. Indeed my searches have found only one other image, produced by the Chart32 team in Chile.

This is a sequence of the lunar eclipse 2019.

Santiago de Chile.

Reading from left to right, you can see how the Earth's shadow cone covers the lunar surface, until it is completely submerged in a reddish copper color. This particular color of lunar eclipses is due to the shadow cast by the sun on the earth, generating a scattering effect of the light refracted by its atmosphere.
