"Astropotes" (which means "astro-buddies" in French) is a collaborative astrophoto group created in June 2019.

The principle is simple: each membre can share its own raw files on the same objects, chosen by the majority of the members, in order to cumulate long exposure time and to produce deeper collaborative images.

We chose to start our collaboration with an image of a nebula and an image of a galaxy, in order to define the potential of our pre-processing and processing workflow on these two types of objects.

We are pleased to present you our second achievement on a classical object :M101, with a global integration time of 72h05 !

Raw files : Frédéric Girard, Nicolas Kizillian, Valentin Cohas, Baptiste Zloch, K-mille Colomb, Jean Baptiste Auroux & Thomas Lelu.
L : 37h25, R : 8h30, V : 5h15, B : 4h45, H : 16h10

TIC 4603 - The Turbulent Heart of the Rho Ophiuchi Complex

BEST DETAILS:
https://www.astrobin.com/full/suxm72/B/

This image shows the core region of the Rho Ophiuchi Complex, centered around the prominent blue reflection nebula IC 4603.

The bright star is 7.9 magnitude SAO184376 which is the main source of light for the blue reflection nebula. The contrasting red areas towards the top are primarily due to reflected light from the hearby red giant star Antares, which lies outside the field of view

Caroline, I'm usually not a very great fan of Hubble palette images, but yours a fine picture, and I'm impressed that this is your first post at Starship Asterisk*. If I understand you correctly, the raw images for your picture were acquired under a pretty light-polluted sky, which makes your achievement even better. Also, if you don't mind my saying so, there is no great surplus of female astrophotographers here. So welcome to Starship Asterisk*!

Moon 84%

Made with saturation technique, moon in color.
I'm offering a tutorial with which I learned the technique: https://photographingspace.com/find-the ... on-photos/

The moon is usually seen in subtle shades of gray or yellow.
The different colors are recognized to correspond to actual differences in the chemical composition of the lunar surface. Blue hues reveal areas rich in ilmenite, which contains iron, titanium and oxygen, mainly titanium, while orange and purple show relatively poor titanium and iron regions.

White areas are taller areas that are most exposed to the sun.
Trips to the moon have already been indicated by similar images.

Omega Centauri (ω Cen or NGC 5139)

Omega Centauri is one of the most striking constellations in the southern sky. The Milky Way flows through this celestial expanse whose wonders also include the closest star system to the Sun, Alpha Centauri, and the largest globular star cluster in our galaxy, Omega Centauri (aka NGC 5139)

Collinder 399 or Al Sufi's Cluster is a random grouping of stars located in the constellation Vulpecula. The stars form an asterism which has given rise to its name as the "coathanger".

This is an image of the central section of the Milky Way from the Eagle and Swan Nebulae to the Lagoon and Triffid Nebulae. The image was taken with two different focal lengths (a 70mm Lens for the widefield and a 5 inch refractor for the details in the nebulae). Total imaging time approx 70 hours

A very unequal pair - HFG 1 and Abell 6

Hello everyone!

While Abell 6 represents a more "classic" planetary nebula, HFG 1 is a little more special.
It was discovered in 1982 by Heckathorn, Fesen & Gull. Its "central star" is a double star system of a red giant and a white dwarf. The structure of the PN is partly due to this. On the other hand, the PN is deformed by immersion in interstellar matter. It moves with its central star into a cloud of gas and dust. The front part is slowed down and a typical "shockfront" is created, at which the nebula also shines brightly.

Sh2-112

Sh2-112 in SHOrgb by Jose Carballada, on Flickr

Sh2-112 is a visibly emitting nebula in the constellation of Cygnus.

It is located in the northern part of the constellation, about 1.5 ° to WNW of the brilliant star Deneb.

It's a capture with 37.5 hours of integration in narrow band with stars in rgb. I used a RC10" at 1500mm and CMOS camera.

This nebula is located in Ha emissions dense area. The background 'soup' is absolutely present in all the capture.

Analemma of the Sun
Copyright: György Soponyai

My fourth Solar analemma photo was taken between 2018-09-24 and 2019-09-15 at local noon (11:44 CET) in Budapest. Standing on Margaret Bridge and looking to South you can enjoy the most breathtaking panorama of the capital city of Hungary: the building of Hungarian Parliament, the Chain Bridge, the Castle of Buda and the riverbank of Danube -- no wonder this area has been a UNESCO World Heritage Site since 1987.
Unfortunately I had some data loss of my camera's memory card so two dots are missing from the topmost of the "8" curve.
I took the foreground photo on 13rd of December, 2018. Initially I planned capturing a simple "Solar dot" and I was quite angry due to the clouds but quickly realized a cloudy foreground scene might be a cool idea.

That's a brilliant photo! Thank you!

There are two little elongated objects in the upper right corner. Could they be distant background galaxies (naah, not sufficiently red for that, I suppose), or could they be little baby stars having outbursts?
