Image Description and Details : This dark nebula lies at a distance of 1200 light-years from Earth in the Constellation of Cepheus. Because the nebula is in the Milky Way's plane it stand outs from the background filled with colourful stars of our galaxy, a keen eye can also distinguish three separate dense dust cores that actually are star formation regions.

Image Description and Details : Reworking of a previous photo highlighting the NFI that characterizes the cluster of the Virgin.
The IFN (Integrated Flux Nebulae) are huge systems of very faint and faint filaments nebulae predominantly not illuminated belonging to the high Galactic latitudes of the Milky Way.
The most extensive system of this type extends along all the northern constellations of the northern celestial hemisphere reaching even the Polar star.
These nebulae have in common the fact that they are not illuminated by a single star but by all the stars of the Milky Way in the vicinity.
Their visibility is conventionally divided between very Bright (those close to M81 and M82), Medium, Faint (weak, as in the case of the Markarian's chain) and dim (poor).
The IFN present in the Markarian cluster is however rather surprising both for its distance from the galactic plane and for its relative brightness although defined as very poor in the details.

During our stay at the observatory, I had a little bit left at the end of the night after our collaboration, so I took the opportunity to take a walk in this dusty area of the sky that had been watching me for a while. I was able to shoot it properly during this moonless weekend.
I really wanted to highlight this epic fight scene between 4 dust monsters, LDN 1228, LBN 550, LBN 552 and LBN 555, that's why I went with this diagonal framing to make it look like one takes over in this battle.
I also wanted to respect the natural colors which I find really beautiful and which accentuate this duality with the bluish and orange hues like ice and fire.

In February, I spent a two week skiing vacation in Arosa, Switzerland. Repeated snowfall made for some of the best snow conditions in years. The drawback was that I only got one clear night for astrophotography during my entire stay.

I decided to spend that night at the Bergkirchli (Mountain Chapel). Built in 1493, one year after Kolumbus discovered America, the chapel is the oldest building of Arosa. I found that it aligns nicely with the Winter Milky Way and Orion.

I share with you my last take, it is an area that contains several dark nebulae, LDN1158, LDN1157, LDN1148 and LDN1155 among others, an object also called the Gyulbudaghian nebula, named after the Armenian astronomer Armen Gyuldubaghian who discovered it in 1977.

and a Daystar Quark Chromosphere Solar filter before the camera.
Approx 1500mm F/L.
Composite of two separate exposures.
Lower exposure for the Suns Chromosphere, slightly higher exposure for the Prom.
Incidently, the main prom size reaches out roughly 180,000km. you can see a faint afterburn which continues for approx another 80,000km.
Measurements based on suns diameter and curvature, derived from a full disc image of this event.

Image Description and Details :

The fantastic Coma Cluster (Abell 56) located 330 millions light-years away in Coma Berenice contains over 1000 identified galaxies. Along with the Leo Cluster (Abell 1367), it is one of the two major clusters comprising the Coma Supercluster.The central region is dominated by two supergiant elliptical galaxies : NGC4874 and NGC4889, and as is usual for clusters of this richness, the galaxies are overwhelmingly elliptical, with only a few spirals of younger age near the outskirts of the cluster.I wanted to capture this object for a long time and I'm glad I could do it from my downtown Bortle 6-7 sky.Newton 250mm f/4 on IOPTRON CEM70 mountCamera ZWO ASI2600mm + Antlia LRGB filters23h50 exposures in February and March 2022 from my backyard.L : 232 x 300sRGB : each 18x300sProcessed with Pixinsight and Photoshop

NGC 5054 is a beautiful spiral galaxy in the Virgo constellation. The galaxy is small in the field of view at an apparent 4×2’. The galaxy has an irregular shape with two of the arms bending back around the galaxy. This small but relatively bright galaxy and allows a reasonable amount of detail and color to come through. This is amazing when you consider that the light from this galaxy has been travelling for 82 million years towards us. The dust lanes are quite evident, as are the star forming areas of the two major spiral arms. These are within the bluish regions of the arms. Its irregular shape suggests a possible interaction in the past.

The background is littered with hundreds of small galaxies. You can go to website to see wider version.

There is so much nebulosity in this region that I just couldn’t stop piling on data to see what would be revealed.

I hope you enjoy this image as much as I enjoyed creating it!

Image Description and Details : NGC 2736 The Pencil Nebula is a gorgeous deep space object in the constellation Vela. Moving at roughly 644,000 kmh it is thought to have been formed from a shock wave of the larger Vela Supernova Remnant. It resides about 815 light-years away.
This target was shot using narrowband filters to create an HOO-palette image. 75 x 600s sub-frames were shot over 4 nights for a total integration time of about 12.5 hrs.

Image Description and Details : LDN 1251 is a complex nebula in the constellation Cepheus, containing reflective dust and gas. Its nickname is the Rotten Fish Nebula. The acronym "LDN" refers to Lynd's Catalog of Dark Nebulae.

LDN 1251 is quite close to us, about 1,000 light years away.
When the light (emitted or reflected) of this nebula "left" to hit my photographic sensor, Robert II "the Pious" was king of France. William the Conqueror had just built the Tower of London and the Vikings arrived on Canadian soil.
