NGC 1491
Located on the edge of a vast cloud of gas, about 10,700 light-years away in the constellation Perseus, NGC 1491 is also an H II region (a large, low-density cloud of partially ionized gas in which star formation has recently taken place). Its central star (BD +50 886), is a young blue star with an 11.22 magnitude whose stellar winds are blowing a bubble in the surrounding gas.

Here is my submission
Copyright: Anthony Sleiman

The Shark Valley Observation Tower is a classic example of Mission 66 architecture, which is sometimes called "modern parkitecture" and features large slabs of concrete, swirling ramps, flat roofs, and terraces supported by thin columns. Providing panoramic 360-degree views of the River of Grass, the Shark Valley Observation Tower is accessed from the midpoint of the 15-mile (24 km) Tram Road.  In this photo, we can see one of the most famous landmarks of the Everglades and the Milky Way galaxy lining up with the highest point of the tower. This photo was taken on August 23, 2020 and is a single exposure shot at 16 mm, 20 seconds, iso 6400 F4

Orion and the visitor

Copyright: Robin Onderka | www.instagram.com/robin_onderka

What is that green bulb next to the Orion’s belt? At this time, you can observe and photograph beautiful Comet C/2020 M3 Atlas, which is currently passing by Orion Constellation. Although not as majestic as Comet Neowise, it is definitely worth mentioning.

In the photo you can see the constellations that are typical of the winter sky in the northern hemisphere. They beautifully stretch over the mountains and cities of Slovakia, which are shrouded in mist. Thanks to the modified camera and long exposures, you can also see a lot of details of the emission (red) and reflection (blue) nebulae of these constellations. if you look closely, you will also see a Gegenschein and a soft airglow.

Amateur Detection of Light Echoes from Supernova 1987a
http://www.rolfolsenastrophotography.com
Copyright: Rolf Wahl Olsen

This image shows what I believe is the first amateur detection of light echoes from SN1987a - 33 years after the event!
The light echoes are produced when the initial flash from SN1987a is subsequently reflected off interstellar dust as light travels outward from the event. Direct light from the supernova was observed on Earth in 1987, and we then see light reflected from dust in the interstellar space arriving later because it has travelled further to reach us.

The image was created by subtracting two Luminance images taken almost 8 years apart, on 24th Oct 2012 and 21st Sep 2020 respectively.
The light areas in the image represent areas that were brighter in 2012, and dark are areas that were brighter in 2020. The light echoes appear as concentric roughly circular arcs, centered on SN1987a's location. This clearly shows how they have expanded during the 8 years.
The echoes also appear to be moving outwards at superluminal speed: With a shift of ~47 pixels in the image, and an image resolution of 0.764"/pixel, the movement corresponds to around 28 light years at the distance of the Large Magellanic Cloud where the supernova occurred (163,000 light years away). This is clearly much faster than the speed of light given there are only 8 years between the images. This apparent superluminal speed is only an illusion though, and does not represent the actual speed of the outward travelling light (see https://en.wikipedia.org/wiki/Superluminal_motion)

To create the difference image I first aligned the 2012 image exactly to the 2020 image, using star alignment and frame adaptation in PixInsight. Afterwards the two images were background subtracted to ensure the best possible comparison and to, hopefully, allow the detection of any faint arcs from the light echoes. Lastly, I subtracted the 2020 image from the 2012 image using PixelMath to reveal the difference that had occurred over 8 years. I was surprised to immediately see very large and prominent light echoes centered around the SN1987a location!
For a final touch, a light noise reduction has been applied to smooth the background.

I'm not sure if Tarantula nebula in the lower right indeed got brighter over the last 8 years, so its presence in the difference image may just be a result of slightly uneven illumination between the two datasets (they were taken with two different telescopes).

Robin, that's a wonderful photo! I love it! The blue-white gems of Orion's Belt are suddenly, mysteriously, joined by a brand new green emerald, which seems to be an extension of Orion's Belt and at the same time give it a kink!

I love the entire skyscape here as well, the composition and the colors. But my eye is inexorably drawn to this amazing version of Orion's Belt! :D

With or without fog
https://www.lucperrot.fr/
Copyright: Luc Perrot

It is often easy to plan a photo and compose with a landscape and a piece of sky and Milky Way. On the other hand, the weather is always an unpredictable element reserving good or bad surprises.
For this series, I was determined to photograph this Milky Way descending above the Cirque de Mafate in Reunion. It was the bridge between two of the highest peaks on the island, the Grand Bénare and the Morne de Fourche.
And then the fog arrived giving me the opportunity to take the same photo but with two totally different atmospheres.
With or without fog?

Galaxy M94
Full version : https://cdn.astrobin.com/thumbs/qXsGhtk ... czOqwr.jpg

Hello,

For this image of the M94 Galaxy, I tried for the first time the "trendy" software "Topaz sharpen" for this image ; as many users do so now for their astro images.

The process was only applied on the inner core of the galaxy, and with many precautions (mask, low % of blend with the original… ) and rigorous verification that no virtual detail is created during the process.

For this image, most of the detail come from classic deconvolution and HDR processing on Pixinsight ; Topaz was only useful to quickly give a "sharpen" aspect to the core of the galaxy.

I think that used in that way, and with such precautions, it can be an interesting tool.

Setup : Takahashi TSA102 / AZEQ6 / CCD ArikOne6 / LRGB-Ha / Guiding : DO-AtikGP

L : 60 x 600s (bin1) + 15 x 180s (bin1) for HDR composition.
R/G/B : 3 x 20 x 180s (bin2)
Ha : 12 x 600s (bin1)
Total : 15h45

IC 1613
IC 1613 is an irregular dwarf galaxy, 2.3 million light years from earth. There is little dust associated with it which enables many background galaxies to be seen through it. IC 1613 helped astronomers work out how to utilize variable stars to determine the expansion rate of the universe. IC 1613 most closely resembles the nearby, transition-type dwarf galaxy Pegasus.
There are many blue star clusters and there is a bright HII region in the upper left.

I'm proud to show you the result of a very huge work at Pic du Midi to make a complete map of Mars during this opposition. It should be the best map of Mars ever done from the ground.
5 nights with various observers have been necessary to obtain this result, and it took me about 30 hours to process it.

In addition to the previous post, here are two stereo pairs show the rotation in 3D:

http://www.astrophoto.fr/mars2020_croise.mp4

One uses the parallel technique. Two rolls of paper or cardboard, held like binoculars, can help to direct each eye towards the corresponding globe (left eye for the left globe, right eye for the right globe).
The other uses the cross-eyed technique: squint to merge the two globes into one at the center of the frame. A finger or any sharp object in front of your nose can help.

CTB 1 (Abell 85, SNR G116.9+0.1) is a faint supernova remnant in the constellation Cassiopeia. It was originally cataloged by George Abell as a planetary nebula as Abell 85 but was identified by van der Bergh, Marscher and Terzian in 1972 as a supernova remnant based on its appearance in the optical as an almost perfect half-circle of radiative filaments. CTB 1 is approximately 10,000 light years away and physically spans roughly 100 light years in diameter. It is dated to be ~7,500-11,000 years old. (Hailey and Craig, Astrophys. J. 434:635, 1994).

The brightest arcs of the hydrogen shell can barely be seen in a single exposure with my optical train, while the OIII signal is significantly fainter. This image was the result of one of the first datasets collected in my brand new backyard roll-off roof observatory. The ability to squeeze every minute of clear sky was crucial to generate quality data for this faint deep-sky object.

The acquisition is primarily bi-color narrowband (Ha and OIII) and star color is replaced from RGB data. Calibration, stacking, and linear processing of the data in Pixinsight, star separation with Starnet (PI plugin). Non-linear processing in Photoshop CC with denoising using Topaz Denoise AI.

Equipment:

TS ONTC 10in f4
TV Paracorr Type 2
ZWO ASI 1600 MM Pro
Astrodon 3nm Ha, OIII and E-series RGB filters
