SH2-278 in the constellation Orion
Copyright: Mark Hanson

Taken at "Stellar Winds Observatory" a/k/a Stan Watson Observatory at Dark Sky New Mexico

"Billowing crimson waves of hydrogen gas cascade in an ocean of tranquility in this uncommon view of the rarely photographed emission nebula Sh2-278. Adding a ghostly presence to the proceedings are clouds of blue dust glowing by reflected starlight.

The most apparent component of this cosmic vista is the bright rimmed dark nebula LDN 1634 to the left of the image. Although small, but easily discernable, multiple red knots of nebulosity are visible near the center of LDN 1634. These constitute a flow of Herbig Haro objects, tiny jets launched by young protostars that glow by being collisionally excited.

The largest of these is known as RNO 40 and the RNO catalogue of 'red nebulous objects' was published by the astronomer Martin Cohen in 1980. The RNO 40 outflow is driven by a protostar called IRAS 05173-0555 and is also catalogued as HH 240.

Professional studies have concluded that Sh2-278 is either a remnant of the gas in the Orion Molecular Cloud that formed the Orion OB1 association or a cloud that was pushed to its current location by the winds and pressure of the OB association. In the sky, it is located north of Rigel."

Imagine flying over the moon in a space capsule and looking down at the lunar surface. What you would see would be astonishing. This image gives a bit of an impression what you could see flying over the Clavius region in the southern part of the Moon when approaching in orbit from the north. That is why I called this image Moonflight...

This image was recorded by my 10 year old son about 1,5 month ago and I decided, because of the great result he got from this data himself, to see if I could extract even a bit more detail from it. Seeing was perfect that night, so that made this image a nice challenge. Also he made a perfect job from focussing so that a lot of detail was recorded.

I decided to use the drizzle function in Autostakkert to see how much detail I could retrieve. It showed that with the drizzle I could even see more details then in the original undrizzled data. The smallest craters I can find in this image are about 1,7 km wide and I think that's very close to the theoretical limit of my Celestron C11 telescope.

I hope you enjoy it as much as I do...

NGC3372 hubble palette mode.



Carina Nebulae , or NGC3372, is one of the flagship objects of the southern hemisphere because of its size and ease to observe / photograph. 25 hours of poses allow here to reveal many details.
Also note the presence of the nova detected 3 weeks ago

To accomplish my APOD project, I've flown from Italy (Rome) to Sahara desert where i've reached Ksar Ghilane oasis. I've started my solitary walk with my backpack to the desert dunes soon after midnight, in order to find the best sky conditions for my project. After 1km walking, i've found a good area and mounted my stuff: Canon 5D mark4, Canon 16-35 f2.8 lenses, Manfrotto tripod 190 series, Skywatcher Star Adventurer electronic mount. I've shot single and complete arch of the Milky Way, being there was absolutely amazing. Still can't describe what I felt in that magic atmosphere surrounded by peaceful silence and gently wind. I really hope to earn this award. That would be my dream.
Thanks for reading.
Regards.

On March 3, 2017 was the last night in Iceland. After a night walk to a geothermal area, I went to my vehicle and instantly saw an unusual phenomenon, a beautiful Lunar corona. First I shot some shots with the wide angle that I had mounted in the camera, it seemed something dark but when doing bracketing one of them had enough signal to be "stretched" in the postprocessing. I opened the camper quickly mounted the telephoto lens in the camera and shot the moon to capture the phenomenon in more detail, seconds later it vanished. Here the shots of the phenomenon, as you can see the telephoto lens I got something "moved" because I did not have time to mount the tripod, rather, when I did it had already vanished.
The shot with the wide angle we also see the alignment between the Moon, Mars and Venus.
The Lunar corona occurs when we have clouds in front of the moon and these are very thin. The effect created is due to the diffraction of light around the small drops of water that contain these clouds that cause light to "split" in its primary colors, like a rainbow.
