Sh2-132 is one of the 312 bright emission nebulae catalogued by Stewart Sharpless. This large area of emission nebula in the constellation Cepheus glows from the characteristic red light of ionized hydrogen. Sh2-132 is about 1,200 light years away. Dark patches within it are due to soot blocking out the light. There are also some prominent dark nebulae blocking out the light of the stars behind them outside the main area of Sh2-132.

Hi all !

Here is the famous NGC6188 Fighting dragons of Ara.
LRGB processing from a free data set provided by Deep Sky West remote observatory and taken with Takahashi TOA150 and FLI ML16200 camera.
Exposure : 20h15

Best regards,

Mathieu

This is an exceedingly lovely image. The details are beautiful, and the colors are superb.

Thank you!

Real Star!

Each of the following movie stars owes its name (or surname) to real stars, so I decided to represent them using tens of thousands of shots taken of their relative stars.
Using an Askar FMA180 on an Az-GTi, shooting with the QHY163C and the L-Pro filter, from the city of Brescia (Italy), with a Bortle 7 sky, I shot, in their real colors, three very famous stars, Sirio, Betelgeuse and Vega.
Blurring the focus slightly, I captured thousands of frames with SharpCap, saving them directly in TIFF and then converting, cropping and debayerizing them with PIPP, and then feeding them to AndreaMosaic for the final composition.
Each single dot is unique and is not repeated, but above all it shows the original colors of the star, they have not been altered in any way.
Filming (in groups of a few thousand at a time) was all carried out in the night between 19 and 20 December 2021.
Although each portrait is made up of around 10,000 photographs, many more were taken to make sure the dots were all different and to cover most of the dynamic range, shooting with different exposures (for nuances) for a total of 58628 shots and 32 GB of data!

That's a neat idea! I like it! And I appreciate the work that went into it.

The dark dusts of Taurus subtly iluminated by stars

A typical astrophotographic fall-winter classic - the California Nebula, Pleiades and countless amounts of dust on the border of the constellations of Taurus and Perseus, subtly illuminated by bright stars, with the super-bright Aldebaran just behind the lower right corner of the frame. The material collected during the last two nights of the October trip to the Bieszczady Mountains.
2-frame mosaic - 54x120s (top) and 63x120s (bottom), Samyang 135/2 and a modified Nikon D610. Place - eastern Carpathans / Poland

The image shows a direct comparison of the activity of the comet only one day apart. We can clearly see the material being ejected and the action of solar winds carrying it away, distorting the shape of its tail.

Still image and an animation if requested of The James Webb Space Telescope cruising along to its destination on December 29th. Several hours ago it deploy and unfolded the Forward Unitized Pallet Structure (UPS) of its vast sunshield. Now the next key steps will be to unfold the Deployable Tower Assembly, release the sunshield cover and begin unfurling the sunshield itself on the 31st.

NGC 3293 SHO by Mathieu Guinot, sur Flickr

Hi all!

Here is the famous and beautiful open cluster NGC 3293 in the Carina constellation.

The HSO filters allow to show the amazing emission region in which it is located, which looks like a cosmic painting (remembered me the fabulous IC 5068 region).

I tried to give a natural tint to the stars, although RGB exposures would have been better and maybe i will add it later!

Data from Telescope Live (6h10 Bundle set from 6 one click observations) taken from March to July 2021 with CHI-1 telescope at El Sauce Observatory, Chile

Hope you like it and happy end of year to all!

A colorful cosmic rose: A collaboration of 110+ hours of data from three continents by William Ostling, on Flickr

Full version: https://theastroenthusiast.com/wp-conte ... otated.png
Starless version: https://theastroenthusiast.com/wp-conte ... osette.png
I highly recommend opening the full version to take a closer look at some of the finer details revealed by the large integration time. A starless copy is also provided to show off fainter detail.

This incredibly detailed image of the Rosette nebula was created from more than 110 hours of exposure across three continents — Europe, USA, and Oceania. We combined 1064 subframes and 6791 minutes of exposure to reveal faint details previously masked by lower amounts of data. The high exposure time also allowed us to sharpen fine features, giving the image more contrast and revealing more fine structures.

On the top of the image lies a wispy structure of bok globules and dust, framed by the glowing ionized gas behind it. The center of the image displays the faint particle streams created by sulfur and oxygen gas blown away from the bright cluster of stars. Just below the center of the rosette nebula lies a beautiful mountain-like structure created by sulfur and hydrogen gas. Through the center of the image, faint wisps of glowing sulfer gas are visible above the dominant oxygen gas.
