I was saving this image for a special moment, so I decided to post it here, for me it was my best moon image of last year.
The Moon is usually seen in subtle shades of gray or yellow
The different colors are recognized to correspond to real differences in the chemical composition of the lunar surface.
The blue tones reveal areas rich in ilmenite, which contains iron, titanium and oxygen, mainly titanium, while the orange and purple colors show regions relatively poor in titanium and iron. The white / gray tones refer to areas of greater exposure to sunlight.
Moon trips have already been guided through similar images.

The Pleiades

Here is a picture I photographed of the Seven Sisters also known as the Pleiades

Pléiades by Martin Giraud

Social :

I shot this pic during an astrophotography session at the Cosmodrome Observatory in south of France. The observatory is perched at the top of the mountain at 1400m, and this night was quite cold. The temperature was -2°c but the feeling was -7°c because of the wind. In those conditions it’s not alway easy to do things well.

So for the final picture is a stack of 158 pictures. Where each picture has the following settings :
50secs - ISO3200 - f4.9

Equipment :
Redcat 51 - Star Adventurer - Canon 6D

Jewels in the southern sky!
This photo shows one of the most beautiful open star clusters of the southern sky - NGC 4755.
It is an extremely brilliant and famous object when viewed through a binocular or a telescope. The orange star is DU Crucis and a red supergiant, strongly contrasting with the other bright members which are blue supergiants.

Solar corona from New York, December 10, 2022

While we wait impatiently for the 2024 total solar eclipse and others around the world, we can view and image the solar corona by making our own eclipses. The attached coronal image was taken on December 10, 2022 in New York State using a 50mm homemade coronagraph, a 5303 Angstrom filter that shows Fe XIV light from the E-corona, and an ASI1600MM Pro camera. It was a relatively quiet day on the circumference of the Sun, allowing the exposure to focus on the dimmer parts of the corona that surround the Sun, with its beautiful streamers and loops. This image was created from a pair of 30-second videos, one taken with the filter at its operating temperature and one 20C cooler (thus eliminating the corona). This process minimized the fringing and circular reflections inherent in the filter.

The Black Sun
I imaged the Sun in the narrow band of Calcium K. To obtain this picture, I used the photo output, of which I subtracted the median of it -- in essence, the limb and its darkening -- and the result is the brighter-than-their context regions. The differential rotation of the Sun becomes more than obvious, as the active regions appear almost similar to Jupiter's cloud bands, and why not, Earth's clouds.

While observing the Sun, I didn't even notice the plane crossing -- only that the stack got ruined. For the attached picture, I used one single ~5ms exposure of the Sun with the plane, and a 4'33 (yes, intentionally 4'33") pristine stack of the Sun, hence, between the original frame, of which only the plane remains, and the stack, the prominences have moved/changed.

Spiral Galaxy NGC 3147 from Hubble by William Ostling, on Flickr

Full write-up here: ... om-hubble/

The graceful, winding arms of the majestic spiral galaxy NGC 3147 appear like a grand spiral staircase sweeping through space in this Hubble Space Telescope image. They are actually long lanes of young blue stars, pinkish nebulas, and dust in silhouette.

The beauty of the galaxy belies the fact that at its very center is a malnourished black hole surrounded by a thin, compact disk of stars, gas, and dust that have been caught up in a gravitational maelstrom. The black hole’s gravity is so intense that anything that ventures near it gets swept up in the disk.

The disk is so deeply embedded in the black hole’s intense gravitational field that the light from the gas disk is modified, according to Einstein’s theories of relativity, giving astronomers a unique peek at the dynamic processes close to a black hole.

NGC 3147 is located 130 million light-years away in the northern circumpolar constellation Draco the Dragon.

Winter Milkyway Panorama Arch over Al Monfareda Mountain.

Image is a composite of the Winter Milkyway over Al Monfareda Mountain. Al Monfareda means the one or only one being a single mountain near Valley of Whales in Fayoum desert.

Category ( Panorama - Tracked - Blended)

I have been dreaming of creating a winter Milkyway panorama since last winter, and I finally was able to do it! Image is a composite where the foreground was shot in December during the Geminids meteor shower, but unfortunately, the sky panorama failed to stitch, so I re-shot the sky pano on the the 27th of December. Will shoot the arch again soon and try to get a 3rd row to make the projected pano more flexible as it wasn't as easy with just 2 rows.

Messier 46 & NGC 2438

Messier 46 was the first object Charles Messier discovered after he had published the first edition of his list (M1-M45).
He added this one to his catalogue on February 19, 1771, three days after presenting it to the academy, together with three more Messier objects, M47, M48, and M49.

The cluster is very rich, with 150 stars of mag 10-13 and probably a total population of over 500. The brightest of these stars are of spectral type A0, and each about 100 times more luminous than the Sun (the brightest is of apparent magnitude 8.7). This indicates an age of about 300 million years. The members are scattered over an angular diameter of about 27', corresponding to a linear extension of 30 light years at the cluster's distance of 5,400 light years, and are receding from us at 41.4 km/sec, according to Baade. M46 is classified as of Trumpler type II,2,r.

As a special and famous feature which is also obvious in our photograph, a planetary nebula (NGC 2438, also FC 87) appears within the apparent borders of M46. This object appears to lie near the northern fringes of the cluster. However, this nebula is most probably not a true member but is superimposed, or perhaps a passing "guest".

IC405 - HSO
High Definition Image here : ... sp=sharing

I captured the data from my drive in Tockwith (England – Bortle 4) over three nights between 14th December 2022 and 02nd January 2023.

The Ha and SII data was captured under poor seeing, guiding was very difficult, and a significant moon - in the case of the SII data the moon was also very close to the target. I therefore expected to have issues with removing the gradient from this data but actually this was relatively small, the 3nm filters did a good job, and not too difficult to remove.

The OIII data was taken on a moonless night with excellent seeing but revealed weak OIII content for this target.

I had intended to process the image as SHO but found the weak OIII resulted in a “red” image which was not what I was after. After a lot of experimenting I arrived at an HSO combination that gave these colours. This is the first deep space image I have produced which includes strong green nebulosity but this is due to the strong SII content of the nebula.

I am pleased with the colour of the stars in the image and although they look similar to RGB stars they are from the same Narrow Band data – I processed the stars as SHO, which gave better colour than HSO, and then merged them back into the image.

This image makes a superb full size poster print.
