Image Description and Details :

Situated on the edge of the Perseus molecular cloud, van den Bergh 18 is a small, faint reflection nebula (blue, center). It is surrounded by various LDN and LBN dark nebulae, as well as several PGC galaxies and the open star cluster NGC1342, (bottom right). This image consists of LUM + one shot color data simultaneously captured from two scopes: a CFF 135mm APO refractor with a ZWO ASI6200MM CMOS camera, and a CFF105mm APO refractor with a ZWO ASI2600MC CMOS camera. In total, there is 26 hours of data for this image, processed with PixInsight.

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.

Sh2-132 in HOOrvb made by Team AstroNew in France in the region of Normandy (Perche) and in Lorraine (côtes de Meuse) . This Team is composed of Francis Bozon, Stéphane Gueyraud.Sh2-132 is a large emission nebula visible in the constellation of Cepheus. It is located on the southern edge of the constellation, on the border with the constellation Lacerta, along the plane of the Milky Way.These acquisitions were made with Newton telescopes (250-900 F/D 3,6), on Eq8 mount and Moravian G2 4000 camera.The exposure times are as follows:Ha= 53X20'O3=50X20' Red= 9x5'Green =23x5'Blue=15x5'That is a total time of about 38,25 hours.

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.

Ced 51 is an interesting juxtaposition of dark and light, containing dense dark nebula in the foreground abs curing portions of the greater hydrogen nebula flowing in red. Right in the middle is an active star forming region birthing new bright blue stars. Part of the greater lambda orionis ring (head of orion), this nebula complex is approximately 5000 light years from earth in the constellation of Orion, the hunter.

Technically, this was a challenge as to do the area justice, we shot a 4 panel mosaic to frame it right.
