Image Description and Details : Gassendi, an amazing crater.
Normally, when we start astrophotography, our first target is the Moon. Our old Lua is generous because it works well even on the most modest instruments. A simple 60mm scope and a cell phone already allow for interesting photos.
But shooting the moon in high resolution requires good apertures, proper collimation and a dedicated camera, and it can be difficult work if the photo is close to the terminator.
But, in fact, it is the photos close to the terminator that reveal the good lunar photographers, as they require adequate control of light, both at the time of capture and in subsequent processing.
In this photo we have Gassendi very close to the terminator, and with the sun at an extremely low angle, the relief of the floor stands out in a dazzling way. Its rhymes are usually very evident but with the sun low we can clearly see how irregular the floor of this remarkable crater is.
Gassendi is one of the main lunar craters, with its 114 km in diameter, it is very old formed in the Nectariam period about 3.92 billion years ago.
It is an impact crater with Fractured Interior (FFC), which was modified by volcanic action after its formation, probably huge lava flows gushed through the cracks in the floor, causing numerous stress fractures to form in its interior from the reservoirs. of lava, this made it quite shallow in relation to its diameter - just 2.8 km deep.
When observed through spectroscopic analysis, the Gassendi crater has a "behavior" very different from any other lunar crater (Mikhail 1979). High-resolution studies performed in near-infrared light (Chevrel and Pinet 1990, 1992) indicated the presence of extrusive volcanic material (that is volcanic material that flows to the surface and then crystallizes) limited to the adjacent southern part of the Gassendi floor. to the floor of the Mare Humorum.
Interpretation of the data also suggested that major extrusive volcanism may have occurred in the eastern portion of the floor, as indicated by the significant presence of pyroxene, which corresponds to visible volcanic features. The western part of the crater floor, away from the geometric continuation of the western rim of Mare Humorum, is composed of rich upland material.
The difference between the west and east sides of Gassendi with intensely fractured soil could be strongly linked to the early thermal history of Mare Humorum.
I've already taken countless photos of Gassendi, but the result of this one with the sun very low really surprised me. A pleasant surprise, which shows that each photo is unique in itself and each moment is unrecoverable if we don't know how to take advantage of it.

Image Description and Details : SH2-308 - commonly dubbed as the Dolphin-Head Nebula by astrophotographers - a HII region located near the center of the constellation Canis Major.

It is thought to have formed about 70,000 years ago by the ejection of the outer layers of the star EZ Canis Majoris.

Image Description and Details : LTNF 1 is an extremely faint and rarely-imaged highly-evolved planetary nebula in the constellation Ursa Major. It is a high-excitation nebula with an eclipsing binary star system (BE Ursae Majoris) at its centre which has resulted in its unusual morphology. It is around 5,000 light years from Earth. It is so transparent that galaxies can be seen through it. It was discovered by James Liebert, Richard Tweedy, Ralf Napiwotzki and Michael Fulbright in 1995. A joint project with Sven Eklund.

Image Description and Details : HFG-1 was discoverd in 1982 by Heckathorn, Fesen and Gull. Its central star is actually a binary star system, V664 Cas (magnitude 14) that is moving through our galaxy. V664 Cas consists of a white dwarf star and a large red giant, rotating around their centre of gravity every 14 hours. As HFG 1 moves through the ISM a bowshock is produced in front of it as well as a red trail of gas in its wake. Outer diameter about 15 arcmin.

Image Description and Details : LDN 1622, also referred to as the Boogeyman Nebula, is a dark nebula that appears against the glowing Hydrogen of Barnard’s Loop in the constellation of Orion. However, LDN 1622 is thought to be much closer than Orion's more famous nebulae, perhaps only 500 light-years away. Its foreboding appearance lends this dark nebula its popular name, the Boogeyman Nebula.

Image Description and Details : There is a grouping of reflection nebulae in Orion - NGC 1977, NGC 1975, and NGC 1973 - usually overlooked in favor of the substantial glow from the nearby stellar nursery better known as the Orion Nebula. Found along Orion's sword just north of the bright Orion Nebula complex, these reflection nebulae are also associated with Orion's giant molecular cloud about 1,500 light-years away, but are dominated by the characteristic blue color of interstellar dust reflecting light from hot young stars.

The Fox Fur Nebula is a nebula (a formation of gas and dust) located in the constellation of Monoceros not far off the right arm of Orion and included in the NGC 2264 Region.

The image is a close-up of a small section of a much larger complex, generally known as the Christmas Tree cluster. The Cone Nebula is also a part of this same cloud.

The red regions of this nebula are caused by hydrogen gas that has been stimulated to emit its own light by the copious ultraviolet radiation coming from the hot, blue stars of the cluster. The blue areas shine by a different process: they are mainly dust clouds that reflect the bluish light of the same stars.

Its popular name arises because the nebula looks like the head of a stole made from the fur of a red fox.
