Partial Lunar Eclipse 28-29 October 2023
It was the last Lunar eclipse of the year and I tried to capture it successfully. As soon as it starts entering the umbral region, a dark shadow starts overlapping the moon and making it look like a "Bitten Biscuit." As the Umbral eclipse starts, the bands slowly turn orangish red and the shadow starts overtaking the brightness the Moon until it gets fully covered. The eclipse has no such effect on human beings as the rumours and superstitions roam around. The events of nature are meant to be enjoyed together.
SH2-119. The clamshell nebula
Location: Castillejar, Andalusia, Spain
Image Description and Details: 2200 years ago, when the photons of light left this nebula to reach us, the Earth was definitely another place. The cosmic time machine, the telescope, this time was pointed towards the constellation Cygnus, more precisely towards Sh2-119. Gas and dust envelop the main star, 68-Cygni being mostly responsible for the ionization of the gas around it. This ionization makes the gases all colored at different wavelengths, from blue to green, passing through all shades of brown and orange. The dark nebula filaments above contrast strongly with both the glow of the nebula and the rich field full of stars in the background. These filaments are clouds containing mostly gas (hydrogen and helium) and a minimal fraction of dust (about 1%), responsible for the appearance of the cloud. These dusts, although minimal, absorb the light, making the nebula completely dark. Sh2-119 is a celestial signature of an ancient explosion that released gas and dust into the universe, forming new stars and planets. The silk effect of the nebula makes us think of a white colored pillow in a bed of stars, but, among that dust, stars and planets are forming in the most violent and destructive processes.

NGC 7822
Image Description and Details: Can you see the face in space ? Blue eyes, a dark nose and mouth with curly red hair….
The red in space is ionised hydrogen and blue is atomised oxygen. Cosmic pillars of cold molecular gas and clouds of dark dust – often called elephant trunks – lie within NGC 7822. Powering the nebular glow are the young, hot stars of the Berkeley 59 cluster, whose powerful winds and radiation also sculpt and erode the dense pillar shapes. Stars could still be forming inside the pillars by gravitational collapse, but as the pillars are eroded away, any forming stars will ultimately be cut off from their reservoir of star stuff…..

In this image I composed 3 different sessions: SHO and L-Extreme images taken with my C11HD from my backyard and RGB images taken with CDK500 from Skygems remote service.
M 2-55 and its elusive fragmented bow-shock front
Image Description and Details: M 2-55 is an evolved rarely-imaged planetary nebula in the constellation Cepheus. It was first discovered and identified by the German-American astronomer Rudolph Minkowski on photographic plates at Mount Wilson in 1947. The plates were taken by W.C. Miller with a 10" f/5.2 refractor.
IM 2-55 possesses two sets of bipolar lobes.
It was only in 2020 that a team of Chinese professional astronomers detected an arc of material running from the SE to the SSW. (Chih-Hao Hsia et. al, March 13th 2020, “Discovery of Extended Structures around Two Evolved Planetary Nebulae M 2-55 and Abell 2”). They concluded that this arc was furnishing strong evidence for an interaction of the expanding nebula of \m 2-55 with its surrounding interstellar material. The presence of fragmentation in the arc may be the result of a phenomenon known as Rayleigh-Taylor (RT) instabilities.
