We are about midway through the Orion season and it's crazy to see Orion already risen in the sky when night falls. We really have to take advantage of all these red-emission nebulae while it lasts. Not too long ago, I hiked up the ski slopes of the Mont Jura mountains again to get this shot as Orion was setting in the early hours of the morning.
I really love this view because it really highlights all the visible deep sky objects at 50mm: the Orion region just setting above the tree line, The Rosette nebula and the Chritsmas Tree cluster, the Hyades and Taurus, The pleiades, the California nebula, the dark dust lanes and the light from all the stars in the fainter outer arms of our milky way.
I wouldn't have been able to get all those colors and details if it weren't for the combinations of techniques perfected over a long period of trials and mistakes. It is the result of tracking individual panels (2 rows of 3 pictures) at 50mm with a light pollution filter and an astromidifed camera. The very sharp and bright lens (Sigma 50mm f/1.4) also helped acquire some good data. I really do hope you enjoy the view.

Eskimo Nebula (NGC 2392). KG Observatory.
The Eskimo Nebula (NGC 2392), also known as the Clownface Nebula or Caldwell 39, is a bipolar double-shell planetary nebula 2,870 light-years away. It was discovered by astronomer William Herschel in 1787. The formation resembles a person's head surrounded by a parka hood. It is surrounded by gas that composed the outer layers of a Sun-like star. The visible inner filaments are ejected by a strong wind of particles from the central star. The outer disk contains unusual light-year-long filaments.

- The Flaming Star Nebula (IC 405), embedded in the Milky Way deep in the constellation of Auriga, glows primarily in the light of atomic hydrogen excited by the massive star AE Aur as it rapidly moves through the interstellar cloud of gas and dust comprising the nebula. The wispy blue emission curling away from this 23 solar mass star resembles smoke, giving rise to the sensation that it is “on fire.” The data used to prepare this picture were collected as unguided 1-min sub-exposures at the Burke-Gaffney Observatory in Halifax by a robotic 0.61-m Planewave CDK24 reflector (f/6.5) equipped with an Apogee CG-16M CCD camera and Astrodon broadband (LRGB) and narrowband (H-alpha) filters. The camera output was binned 2x2 to provide a 2048 x 2048 px image-plane with an full field-of-view of 31.9 x 31.9 arcmins2, and a resolution of 0.94-arcsecs/binned pixel. The sub-exposures were integrated using CCDStack (CCDWare) to produce mean grey-scale images of 1.3, 1.1, 1.1, 1.8 and 2.9-hrs duration in the LRGB and H-alpha bands, respectively. The mean H-alpha image was blended in Photoshop (Adobe) with both the mean Luminance and Red images to enhance their detail. The results were high-pass filtered and combined with the mean G and B images to produce the colored image. Stellar profile shapes were corrected to reduce distortions introduced by the lack of guiding, and the final image was cropped to a spatial size of ~11.1 lys in each dimension at the assumed distance to the star.
The posted image was cropped to a spatial size of 12.6 lys (W) x 13.1 lys (H) rather than to 11.1 lys in each dimension as stated originally, assuming that the star powering the emission (AE Aur) lies at a distance of 1450 lys.

Cederblad 51 is a part of the large Sh2-264 nebula, the "Orion's head".Red colour shows the large H-alpha emission nebula (GN 05.30.0), blue the reflection nebulae ( Ced 51) and brown,the dust nebulae (dark nebulae such as: LDN1582,LDN 1584,Barnard 31,Barnard 30..) .Also Herbig-Haro targets such as HH 179 and HH 244 can be guess between dust.

After an evening snowstorm in northeast Wyoming, the clouds cleared out just in time before the lunar eclipse began. Devil's Tower was covered in white, and it was a beautiful scene as the moon entered totality. This was taken just before twilight started drowning out the stars.
This is a combination of 3 exposures, 1 for the moon, 1 for the stars, and 1 for the tower. Shot with a Nikon 180mmf2.8 lens on a Nikon D750.

Lunar Eclipse Over Castle Crags

Pre-dawn lunar trifecta: ‘super blue blood moon’ rising over Castle Crags, located in the far Western region of the United States. The Earth’s shadow slowly wandered its way across the Moon to form the mesmerizing color of totality above its towering spires.
