[bystander]

I have just posted my submission regarding a full map and animated rotation of Jupiter, but made the typical mistake in the links...

I would like to edit my post, but cannot find the way.

The Milky Way from Lama Lite Pass, in the Apennines near Reggio Emilia, emerges from Monte Cipolla, the northern peak of Monte Prado.
Lama Lite, sandwiched between 2 groups of mountains exceeding 2000m above sea level (Cusna to nord and Prado to the south) and with the sparsely inhabited Dolo and Ozola valleys to the east and west, respectively, is able to offer a very dark sky (for those who like measures the sqm is 21.3 mag/arcsec), although light pollution from Tuscany, Liguria and, of course, the Po Valley is unfortunately clearly visible. The brightest star to the left of the Milky Way is actually the planet Saturn, these days in the best visibility conditions of 2022
Technical data: Canon EOS 6D with Samyang 14mm f/2.8 11x25s f/3.5 6400 ISO untracked

ETA Carinae_SHO by Mathieu Guinot, sur Flickr

The colourfull surroundings of Eta Carinae within a 2 panels mosaïc.
I used several Telescope Live data sets with different framing and exposure times that I mixed to get this panorama. The very strong signal at the center of the Carina nebula allows to obtain many color shades in SHO rendering while the focal length used gives access to multiple and fine details, making this area a great pleasure to process, with many rendering possibilities.

The Great Carina Nebula NGC3372 is a large emission nebula located approximately 8,500 light-years away in the constellation Carina. At the center of the nebula, Eta Carinae is a highly luminous hypergiant star, currently the most massive star that can be studied in great detail, because of its location and size. Estimates of its mass range from 100 to 150 times the mass of the Sun and its luminosity is about four million times that of the Sun.

Data acquisition from 2020/11/22 to 2021/05/23 at El Sauce Observatory, Chile.

Scorpus region with C/2017 K2 PanSTARRS
Author: Pavel Váňa
Location: Gran Canaria, Spain
A beautiful nigh at Gran Canaria was spent shooting this beautiful region of night sky in Scorpus. Look at the beautiful nebulae around Antares (the brightest star in this constellation) and dark nebulae. At the right upper corner there is blueish nebula called Blue Horsehead nebula.
Technical data: Canon EOS 6D mod., Samyang 135 mm f/2@2.2, ISO 1000. 137 single shots with exposure time 60 seconds were used and stacked. I used Vixen Polarie mount.

Perfect spiral M74 from JWST and Hubble by William Ostling, on Flickr

Full write-up here: https://theastroenthusiast.com/perfect- ... nd-hubble/

Processing galactic images with both JWST and HST data is just incredible. Normally, every spiral galaxy (and some elliptical ones too) have dark dust lanes obscuring the light from the stars behind. These dark spirals add depth to the image, but unfortunately don’t contain much information. But with the added infrared imagery, the glowing strands and flocks of dust, which would normally be dark in visible light imagery, are instead bright and glowing with infrared light from JWST.

NGC2070_LRGB_HO by Mathieu Guinot, sur Flickr

The famous Tarantula Nebula (also known as 30 Doradus) is a large HII region in the Large Magellanic Cloud (LMC). It is the most active starburst region and also one of the largest HII regions known in the Local Group of galaxies.
At the centre of the Tarantula, NGC 2070 (also known as Caldwell 103) is a large open cluster which produces most of the energy that makes the nebula's gas and dust visible.

I tried pure LRGB processing and SHO processing and finally preferred the rendition of broadband and narrowband combination so i used both data sets (LRGB and SHO) from Telescope Live.

Wolf-Rayet 134 (WR 134) is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. In my image, the Wolf-Rayet star WR 134 is visible in the center of the gas bubble as the brightest white star. Wolf-Rayet stars are extremely hot, bright, massive stars, and one of the rarest classes of stars known. As of 2018, only 154 had been identified in the Milky Way. Some produce spectacular nebula, e.g. the Crescent nebula (NGC 6888), thanks to their strong stellar winds, intense ultraviolet emissions, and clouds of gasses that they shed in earlier stages of their relatively brief lives. Wolf-Rayet nebula around the Wolf-Rayet star WR 134 was first noticed in 1971. The nebula is embedded in the large nebula complex of Sh2-109, so the surrounding area is also filled with lots of emission nebulosity.

The famous constellation Cassiopeia is immersed in the Milky Way. This causes its iconic W shape to be virtually unrecognizable in this long-exposure photo taken from the excellent sky of Lama Lite. On the other hand, some emission nebulae with their characteristic red color are clearly visible. From top to bottom: NGC 7822, the Pac-Man nebula and the famous Soul and Heart duo with the Perseus double cluster to their right.

This was a great target to shoot with a one-shot colour camera: QHY 533C. Even though it was only 90 mins worth of exposure, it was pretty amazing how much duty details it ws able to pull in via my 90mm refractor. Before this, there was a data-loss scare which thankfully did not happen.
Hope you enjoyed it!

A narrowband view of sunspot AR3088

The following image was an experiment in which I RGB combined images of the sunspot taken through different narrowband filters. For red I used a H-alpha filter with a passthrough at 656,3nm. For green I used a SolarContinuum filter with a passthrough at 540nm. For blue a UV filter with the maximum passthrough at 380nm was used. Each of the filtered images was a stack of a thousand selected images out of 7000 each.

Ngc 6559 & IC 4685 by Mathieu Guinot, sur Flickr

NGC 6559 (left part of the image) is a star-forming region located about 5000 light-years away in the constellation of Sagittarius, very close to Messier 8 Nebula and showing both emission (red) and reflection (bluish) regions. At the center, the emission nebula IC 4685 is crossed by the dark nebula Barnard 303.
