POLAR STRATOSPHERIC CLOUDS - from Scotland
Copyright: Alan C Tough

At the beginning of December a polar vortex formed in the north, resulting in low ozone values. The ozone layer temperature fell low enough to allow the formation of Polar Stratospheric Clouds (PSC or Nacreous Clouds): these were well seen from Scandinavia and, to a lesser extent, northern Scotland.

This image was taken from the north of Scotland on 2019 December 03, shortly before sunset.

There are so many great images in this thread already, and I like them all. But I have to mention a few favorites:

Mark Hanson, I love your "negative background portrait" of NGC 134 and galactic friends! So easy to make out details and so generally appealing!

KuriousGeorge, that's a stunning portrait of galaxies NGC 5953 and NGC 5965! And it's a truly superb portrait of elegant spiral galaxy NGC 6384, seen through a thick veil of Milky Way stars!

Kfir Simon, I love the background galaxies in the Witchhead Nebula!

Rey Hernandez, I love the "textures" and colors of the various stellar populations in the great Andromeda galaxy and its small satellite galaxy, M32!

Marc Toso, that's a marvellously majestic portrait of the winter Milky Way gently curving over the similarly curving outline of Three Finger Canyon. It goes without saying that I love the Pleiades peeking out through the opening between two mountainous shapes. I love the intensely blue color of a few of the stars, like Lambda Orionis, whose blue hue is the most azure thing I have ever seen through a telescope. (Tell me, though, did you by any chance duplicate Eta and Zeta Aurigae?)

Martin Heigan, for a lover of all blue things like myself, that is an achingly beautiful portrait of the Pleiades.

Javier Flores Martin, I love that colorful and excellent portrait of the Large Magellanic Cloud!

But let me say it again, I love all the pictures posted here. So thank you, all of you!

(And this is my 9966th post. If you put that number upside down, you get 9966 again. Or do you get 6699 instead? In any case, maybe there is an interesting technical term for that.)

DISCOVERING THE BLACK HOLE OF THE SPIRAL GALAXY NGC 4622

After a few weeks working behind the desk, trying the best to hidden the noise, working to remove the mosaic lines, and scratching until to find out the black hole of this pretty odd Spiral Galaxy known as the Ringed Spiral Galaxy NGC 4622.

Hope you enjoy my work.

Mount Etna meets Alderamin

Description:During the Strombolian eruption of the Sumital Crater south-east of Etna on December 8th just before dawn, the magma gushes into the sky tempered by blue colors, to the right appears a star of the constellation of cepheus, Alderamin about 49 light years away from the earth. An admirable spectacle, where everything is always magical.

M45 on December 8th, 02:59ut. ( ES 80 APO, ST2000xm Ccd, AO8, CF9, Astronomik LRGB filter set.) The Pleiades also known as the Seven Sisters and Messier 45, are an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

The radiant Andromeda galaxy and his friends.

Bubble nebula and friends
Copyright: Thomas LELU I present you a field around the nebula of the bubble comprising:
- an open cluster of stars (M52-NGC 7654: distant about 5000 light years)
- nebula NGC 7538 (active star formation region)
- the bubble nebula (bubble created by the stellar wind of a star), which is about 10 light years in diameter and continues to grow, for comparison the diameter of the heliosphere, the sphere of influence of the Sun, would be close to 35 light-hours only.)

Lagoon Nebula (upper left), Trifid Nebula (lower corner) and Loreta Nebula (upper right)

Located about 3,500 light-years away in the constellation Sagittarius, the nebulae are clouds of interstellar dust and gas. Its red glow comes from ionized hydrogen gas and lit by young hot stars with nebulae. The blue part of the Trifid Nebula is a colder cloud of dust that reflects the blue light of the hot stars. Several small, round and dark areas are seen within the Lagoon Nebula. They are known as Bok globules and are clouds of interstellar gas and dust undergoing a contraction phase that can lead to star formation.

(Syracuse Wednesday, 11 December 2019, 21:10:38) The full moon of December is traditionally
known as the Full Moon of the Cold, from the
moment that in December the winter begins in almost
the whole northern hemisphere and is in the grip
of the cold. This moon is also known
as Full Moon Oak, Long Moon
Nights, and Moon Before Christmas.
The December full moon usually shines in between,
or near, the stars of the constellation of Taurus. From
moment that, on this day of the lunar month,
is in opposition to the sun, the moon completely
illuminated rises at sunset and sets when
The sun is rising. The Full Moon of Cold
December is particular for its high trajectory
through the sky and the fact that it remains above
the horizon

Canon 6d mark ii, canon 70-200 2.8 L ii.

This image is authentic, taken by me personally and I own the raw file. It is not a photomontage, it has only undergone interventions of color in Photoshop and adjustment.

This is a basic picture of the Full Cold Moon.
Taken with Canon Rebel T6, 300mm lens.
I don't have a tripod, so I put a brick on a pine stump to brace the camera as I tilted it up.

Last full moon of the year and the decade! Had to give it a shot.

I would like to submit my picture of M42 and NGC 1977. I know that you must receive a lot of pictures like this, but I am taking my chances anyways as I am very proud of the result and got a lot of great positive feedback. It can show what can be achieve with decent, yet far from top of the line equipment, in an heavily light polluted area.


High Resolution Version

Technical detail:

This photo is a composite of two set of exposures I took on November 30th, 2019.
The first set consists of 20 x 180s exposures @iso 400 and the second consists of 60 x 15s exposures @iso 200. I have combine the shorther subs to to the longer one to get show a bit of the trapezium in M42 as it was overexposed.
Location: Gatineau, Québec, Canada
Bortle scale: 8
Temperature: -5 C
Taken from my front yard, between 2 lamp posts. This really shows that even with heavy light pollution, one can get very good results.

Equipment used:
• Scope: William Optics Zenithstar 73
• Flatener: William Optics Flat 73 (1:1)
• Camera: modded canon T3i
• Guide scope: William Optics Uniguide 50mm
• Guiding cam: ASI 120mm-mini
• Mount: HEQ5-Pro
• Filter: Optlong l-pro clip-in

Taken using APT to control the mount and camera and phd2 for guiding.

I have stacked both set of exposures in deep sky Stacker and then did the following in process in Photoshop CC:
• Removed Gradient using gradient exterminator
• Levels to set black point
• Convert to 16 bit
• Stretched using levels
• Curves edit
• Adobe raw filter for dehaze, clarity, texture and noise reduction
• Isolated the core from the shorter subs and integrated on the longer subs stack using a layer mask and opacity reduction.


I got into astrophotography back in 2014, I was using a simple tripod, a DSLR and an intervalometer. I then got a Star Adventurer in 2018 and started experimenting on DSO and milkey way shots stacking. I got my recent gear back in September of this year and really started to get more serious.

Thank you for your consideration
