I present to you a study on the retrogradation curve of the planet Uranus and its satellites made from December 2020 to February 2021. Retrogradation, or retrograde movement, is the recoil that a celestial body seems to describe when observing it from distant stars. It took 8 nights to image the planet with 50 luminance images of 10 seconds each in bin1 + 20 RGB images of 2 seconds each in bin2 and after assembly, process and annotations of the positions of the planet by date I looked for the position of the satellites visible on these images. So on these images we can distinguish Oberon and Titania, and from time to time we see Umbriel.FPS: 10 fpsexpo: 100msGain: 500total image: 10,000Focal length: 5400Drizzle 3

The Tadpole nebula or IC 410 is an emission nebula in the constellation Auriga. It lies approximately 12,000 light years from earth.

I don't believe its name needs any explanation, it's one of the few I can see immediately, and I've always struggled with most. This nebula reminds me of a line in one of my favorite songs. "We're just 2 lost souls swimming in a fish bowl". Of course Pink Floyd isn't everyone's thing!

This image shows the galaxy M63, also known as the Sunflower Galaxy. What sets this galaxy apart from other spiral galaxies is its extensive halo and tidal stream. These streams often occur when a galaxy has a close encounter with a nearby satellite galaxy. The result is a big stream of remnants of the satellite galaxy.The image was taken throughout February(13.02, 18.02, 20.02, 22.02, 01.03.) and early March, party out of my backyard, party from a dark site, both located near Freiburg in Germany.The gear used was the following: Celestron RASA8, QHY183M, Skywatcher EQ6, TS-Optics LRGB filters. The exposures were mainly 90sec at Gain 0, though some had 60s subs because of the moon. Total integration time amounts to 25hours.Processing was mainly done in PixInsight, although I also used Adobe Photoshop and AstroPixelProcessor. The main challenge was to bring out all the faint dust without "blowing up" the stars and details, PixInsights multiscale processing certainly helped a lot in making that possible.

Here is my latest Hubble Palette (SHO) version, a very wide view of The Heart IC1805 and Soul Nebula IC1848 using data from Grand Mesa Observatory’s System 1a the William Optics Redcat together with a QHY16200A Monochrome CCD, this combination is giving a field of view of approximately 6 x 5 degrees, In this Hubble Palette version the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel. Captured over 6 nights in 2020 and 2021 for a total acquisition time of 15.3 hours. 7000-7500 light-years distant in the constellation of Cassiopeia lie the emission nebulae colloquially known as the Heart and The Soul Nebulae. The gasses (mostly hydrogen) that comprise the nebulae are being ionized by the stars within the region and as a result, the gasses glow, much like a neon sign. The pressures exerted upon the material by the stars nearby are causing the material to become compressed. When enough of the gas becomes highly compacted, it triggers the birth of new stars. In effect, this is a beautiful snapshot of a multimillion-year process of an enormous cloud of dust and gas transforming itself into new stars.

Geminids 2020 meteor shower composite panorama. This years maximum night was really crazy for me. I spent 10 hours on the slope of Elbrus mountain at an altitude of 4000m with completely clear sky and fascinating transparency of the atmosphere. Luckily the weather was calm with modest wind and just -15C degrees.I was lucky to witness ~720 Geminid meteors, catching ~150 of them in frames as my cameras made continiously 1300+ shots. Was easily the most impessive meteor shower i've seen so far with, thanks to unique observing conditions.

I have started this imaging project back at 2010. My aim was to make a high resolution mosaic covering the constellation Cygnus. Work like that takes time and patience, especially since I have worked so, that many of the individual sub mosaics or frames have been published as an individual artworks. Here is a poster format presentation about all of longer focal length images used for this mosaic beside wide field panels.

As a result I have now a huge 37 panel (And 58 long focal length sub-panel) mosaic panorama covering 28 x 18 degrees of sky.  I have collected photons way over 600 hours during past ten years for this photo. The full size mosaic image has a size of about 25.000 x 15.000 pixels.

In the orientation image above, there are three large supernova remnants visible, first the Cygnus Shell W63 , bluish ring at upper left quarter, secondly the large SNR G65.3+5.7 at utmost right and finally the third is a brighter SNR, the Veil nebula just outside of field of view at bottom center. (Image is partly overlapping with large mosaic but I didn't want to include it yet due to artistic composition.)Beside three supernova remnants there are two Wolf Rayet stars with outer shell formations. NGC 6888, the Crescent Nebula at center of the image and the WR 134, it can be seen as a blue arch just right from the Crescent Nebula, near the Tulip nebula.Next to the Tulip Nebula lays a Black hole Cygnus X-1, it's marked in small closeup image of the Tulip Neula at center right in orientation image above.

There are 37 base panels with shorter focal length tools (300mm f2.8 Tokina and 200mm f1.8 Canon) There is also 59 sub-panels used, they are shot with my old 12" Meade and 11" Celestron Edge scopes.

Barred spiral galaxy NGC 1365 is truly a majestic island universe some 200,000 light-years across. Located a mere 60 million light-years away toward the chemical constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax galaxy cluster. This impressively sharp color image shows intense star forming regions at the ends of the bar and along the spiral arms, and details of dust lanes cutting across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole.Location/Date – El Sauce, Chile, December 2020Imaging System – Planewave 17” CDK, 10 Micron GM3000, FLI ML16803 Chroma FiltersExposure – LRGB, 9 hoursProcessing – Pixinsight

Our Milky Way is actually full of dust, but hidden in the black starry background, it is not easy to see. Only by accumulating a long time of exposure, the dust that pervades the stars will show up, presenting rich details of intricate complexity.

This large patch of dust in the picture is part of the Perseus molecular cloud, located at the junction of Taurus, Aries, and Perseus, about 1,000 light years away from the Earth. The dust with a total mass equivalent to 10,000 suns is gathered in clusters or twisted into twists. The thick areas are dense and opaque, and darker than space itself.

In this darkest corner, new light is gestating.

The dust near the center, a little red light came out from it, that was a star cluster forming in it. Beside this dust, a newborn star dispelled the haze, illuminating the surroundings with bright light, and became the brightest deep sky object in this area.

In the new Chinese year of the ox, may the world sweep away the dust, dispel darkness, and reappear light.
