Crescent Moon, Mercury, Jupiter and the Monviso peak
https://stefanoderosa.com/
Copyright: Stefano De Rosa On January 14, 2021, soon after sunset, I have been so lucky to attend from Turin (Italy) a great show in the sky: a beautiful slender crescent Moon in conjunction with Mercury and Jupiter "next to" the Monviso Peak (a 3.841 mt. high mountain of the Italian Alps well known for its pyramid-like shape) immersed in the twilight colors.

Best regards

I'm thinking not Andromeda. It says Rosette at the bottom. That's the one I'm going with.

https://flic.kr/p/2ksvz8u Target was the Leo Triplets. Which you can barely see if you zoom in around the middle. Had just set up and was getting 1 minute subs @ f/2.8 and iso 3200. Focal Length 70mm. When we all saw a bright meteor light up the sky and left a visible to the eye a cloud of gas and smoke. My friend said, bro I think that just went straight through your shot. I'm like no way...but went to check and boom!

Connection with Milky Way

It is a single exposure that shows the milky way core reflected over the Uyuni Salt Flats in Bolivia, South America. In February after the rain season it becomes the largest natural mirror in the world with more than 10,000 km2 where it is possible to see and capture the milky way reflection. In this picture is important to show how the milky way core becomes bigger because it is so near to the horizon (South East) with significant presence of green airglow in the sky. We also can see Mars and Lagoon Nebula reflected.

The UFO Galaxy. KG Observatory, Julian CA.

December and January skies haven't been great this year – mostly overcast and unsteady.

Fortunately I found a few steady clearings to capture this UFO Galaxy (NGC 2683) which was well-positioned from 9 PM to 5 AM.

"NGC 2683 is a field spiral galaxy discovered by William Herschel on February 5, 1788. It was nicknamed the "UFO Galaxy" by the Astronaut Memorial Planetarium and Observatory.

It is viewed nearly edge-on from Earth's location in space and is located 20 million light-years away.

Blended light from a large population of old yellowish stars forms the remarkably bright galactic core. Starlight silhouettes the dust lanes along winding spiral arms, dotted with the telltale blue glow of young star clusters in this galaxy's star forming regions.

NGC 2683 is rich in globular clusters, hosting about 300 of them, twice the number found in the Milky Way."

VdB 47 (SH2-243?) KG Observatory, Julian CA.

I started collecting color for this faint reflection nebula during a few December nights of decent seeing. I was then lucky to see some clearings during January for the Luminance.

"VdB 47 is a reflection nebula associated with a visible emission in the constellation Taurus.

It is a cloud of gas that surrounds the star HD 37387, an orange supergiant of spectral class K1Ib placed at a distance of 6500 light-years, at the inner edge of the Perseus Arm.

The nebula presents a markedly orange color due to the radiation of this star and has an effective temperature of 4500 Kelvin. The cloud may be associated with star-forming region which also includes the maser DG 68 and the source IRAS 05363 + 2317, along with some radio wave sources.

Some astronomers identify VdB 47 with Sh2-243. In fact, the given coordinates in the Sharpless catalogue place SH2-243 almost at the same place. From Galaxymap: "there is no visible nebulosity on this image, no known ionising stars in this direction, nor has anything been detected at radio frequencies. It is not clear whether this object actually exists".

The same applies more or less to LBN 830. But some further research suggests, that probably VdB 47 = SH2-243 = LBN 830."

http://cosmicobsession.com/images/wfovdolphin.jpg Hey Folks! ... Another one in the books! This is SH2 308, The Blue Dolphin Nebula. Interesting object to image since it was so faint. Deffinitely needed more data and will prob add to next year.
Compiled as an HOO (Hydrogen Alpha and Oxygen III). With using the Starnet routine within Pixinsight, finding it much easier to work on the nebula portion , or the star portion parts of the object!....
Hope y'all enjoy!

SH2-308, Dolphin Nebula
Copyright: Chris Plonski
SH2-308 by Chris Plonski, on Flickr
SH2-308 is commonly known as the Dolphin Nebula or the Cosmic Bubble Nebula. It is located in in the constellation of Canis Major (The Big Dog). It is an HII region seen here glowing red due to the ionized hydrogen gas in its makeup. The main blue area is made up of ionized oxygen gas that is expanding rapidly due to the intense solar winds coming from the bright blue central star. This is a "Wolf-Rayet" star that is many times the mass of our sun and is in a pre-supernova stage of its evolution. Its impending supernova explosion will consume the bubble and surrounding area. The distance from Earth is a contested number ranging from 1900 to 5800 light years away, but largely considered to be 4350 light years away making the bubble about 60 light years in diameter. Quite a large dolphin head!
