M16, Eagle Nebula with its Pillars of Creation. The Eagle Nebula lies in the Sagittarius Arm of the Milky Way, about 7,000 light-years away.

An image of Friday night's (24th) waxing gibbous moon. The moon was almost 12 days old and almost 92% illuminated.
The full moon on the 27th November is also known as the Beaver Moon in Native North American culture. It is also known as the Freezing or Frost Moon as a nod to the weather conditions which become prevalent at this time of year.
Imaged with a Skywatcher Esprit 120ED and a ZWO 2600MC. Some nice subtle colours evident which are as a result of the lunar geology. Comparatively Titanium rich areas giving a bluish colour, whilst those areas richer in Iron account for the more brown regions. The radiating ray systems of Copernicus and Tycho craters are well seen.
Thanks for looking!

Sur cette photo, j'ai capturé la grande nébuleuse d'Orion SH 2-281 et une petite partie de la nébuleuse de l'homme qui cours SH 2-279 en dessous sur la photo.
Ces nébuleuses sont distantes de 1350 années lulières et ont un diamètre de 24 années lumières. Ce sont des nébuleuses en émission (les gaz chauffés par les étoiles voisines emettent de la lumière) et en réflexion (les gaz et poussières reflettent la lumière des étoiles).

[EDIT: Complete reprocessing in Hubble palette (RGB + Hubble HOO)]
In this photo, I captured the Great Orion Nebula SH 2-281, along with a small portion of the Running Man Nebula SH 2-279, visible at the bottom of the image.
These nebulae are located about 1,350 light-years from Earth and span approximately 24 light-years in diameter.
They are both emission nebulae (where gas heated by nearby stars emits its own light) and reflection nebulae (where dust and gas reflect the light of surrounding stars).
Equipment used: Camera: Canon 1200D (partially modified for astrophotography), Filter: Optolong L-Enhance, Telescope: Skywatcher Newtonian 150/750 with beveled edge and coma corrector, Mount: Skywatcher AZ-EQ5, Autoguiding: Kepler 50/162 guide scope + ZWO ASI 120MM camera + PHD2 Guiding on Raspberry Pi 3

Wiki: The Dumbbell Nebula (also known as the Apple Core Nebula, Messier 27, and NGC 6853) is a planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, at a distance of about 1360 light-years. It was the first such nebula to be discovered, by Charles Messier in 1764.
This is a beautiful and easy target for amateur astronomers. This picture is probably my best so far for this target!
Taken with partially de-filtered Nikon D7500 DSLR on Skywatcher Evostar 80ED and Barlow x2. Total exposure time ~12min (6x2min at ISO1600)
The heart of the Heart nebula revisited using the "natural palette" with special attention to the dark nebulas there.
It a complete rework of a previous image made on SHOrgb.
A total of 57 hours of integration and a lot of intermediate version on the process.
Still I think that I could obtain more details, but this will be next year (maybe :P ).

NGC 1499, The California Nebula, lies 1000 light years away and spans 2.5 degrees in our apparent view. This nebula is very bright in Ha, but the pleasant surprise was the OIII signal between the Ha and the star ξPer. I decided to go with HOO only and not include SII signal as the beautiful red and blue contrast each other very well.
The OIII signal extends quite far from the Ha signal and almost looks as if it reflecting the blue light from the star ξPer.
I'm happy with the wide field view of this nebula. It gives a nice broad presentation and the extend of the OIII signal can be appreciated.
Its a different take on this object, as for me the main highlight is the OIII instead of the Ha

When the moon is out and you have finished all your trials. You go back and try and learn just a bit more from old data. I know I want to do this again properly not just a trial shot but quite impressed how it worked out none the less. this was the camera that was faulty why I never looked at the data before right magnification though.

Cloud iridescence or irisation is a colorful optical phenomenon that occurs in a cloud and appears in the general proximity of the Sun or Moon. The colors resemble those seen in soap bubbles and oil on a water surface.

Second completed image of 2021 and the first complete one from my local astronomy club's dark site, an hour and a half outside of Houston. We finally had the first clear new moon weekend of the year, and myself and many others in the club decided we had to take advantage of it. It was a beautiful night with no clouds and the dew kept at bay. Had to image something unique for galaxy season and I settled on Markarian's Chain in Virgo. I framed to to get as many individual galaxies as I could in one shot.

NGC 300 is a spiral galaxy in the constellation Sculptor. It is inclined at an angle of 42° when viewed from Earth and is approximately 94,000 light-years in diameter, which is somewhat smaller than our own Milky Way. It has a very low surface brightness which made it difficult to image from our light polluted driveway.
Once again it seems that every image we do is plagued by issues. From crazy gradients, to focusing issues and tracking problems. This image was taken over two nights, but due to clouds rolling in and wind, we only managed a few hours in total. It was also extremely difficult to process due to its low brightness and we spent hours on this one. As it is summer time here at the moment and it really doesn't get dark for imaging until about 10.00pm, we can only get a few hours imaging of the very few clear nights we get. We really need to be getting greater than 10 hours on each target. Perhaps in the winter time.....

NGC 6744 is an intermediate spiral galaxy about 30 million light years away from Earth in the constellation Pavo. It also has at least one distorted companion galaxy (NGC 6744A) which is similar to one of the Magellanic Clouds. It was discovered by James Dunlop a Scottish astronomer in Parramatta Australia on 30 June 1826.
We are extremely happy with how this image came out considering we lost 15 x 300 seconds of RGB frames due to some issue that I have not identified yet. There were also some extreme gradients which took some innovative processing to remove in PixInsight.

Profitant de rares moments de ciel clair en Décembre 2023 (le 16 décembre pour être précis), j'ai essayé d'imaginer cette belle galaxie vue de la tranche.
Elle est vraiment petite à même pas 600mm de focale mais je suis plutôt agréablement surpris par le résultat !

Galaxy Season is almost upon us so I thought I'd get things underway a little early with a January attempt at two of my favorite galaxies. Here are two gems of the northern sky- M81 and M82, known as Bode's Galaxy and the Cigar Galaxy respectively. These two galaxies are sort of right in the middle of a group of galaxies encompassing the constellation of Ursa Major (the Big Dipper). Bode's is one of the most picturesque and gorgeous observable spiral galaxies in my opinion. The pair reside about 12 million light years away, meaning we are looking at some pretty old light 🔭
Bode's is about 36,000 light years in diameter with approximately 20 billion suns- making it one of the densest known galaxies. It was discovered by EJ Bode in 1774. M82 / the Cigar Galaxy is intricately involved with Bode's and has undergone a series of fascinating and somewhat mysterious gravitational events due to their gravitation intermingling. M82 has rapid and diverse star creation as a result of this cosmic interaction.
Their cosmic dance will "soon" come to an end however as it's theorized that the two will merge into one galaxy within the next few billion years- not unlike our own Milky Way and neighboring giant Andromeda.

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs from Earth. It is the nearest major galaxy to the Milky Way and was often referred to as the Great Andromeda Nebula in older texts... (from Wikipedia)
Being a very large object in our sky, my telescope's 1000mm focal length and 1.25º x 0.83º field of view wasn't nearly enough to capture whole galaxy in one shoot so my choice was "left" part of the galaxy including it's bright core which contains supermassive black whole. In spiral arms there are lots of dust lanes and big blueish star cloud known as NGC 206 along with some of the Ha regions visible. There is also small but bright satellite galaxy M32 near upper edge of the Andromeda Galaxy
I find this fascinating not least because of the 2 for 1 in the field of view!
M35 is the sprawling open cluster 2,800 light years away in the constellation Gemini covering a 30' area with several hundred stars scattered wide. To the South West of that is NGC 2158 sitting on the outer spiral arm of our galaxy at 11,000 light years away. M35 is approx 100 million years old whilst NGC2158 is 10 billion years old.
This was quite a difficult task to process mostly because my DSLR was capturing over 16000+ stars (according to DSS) in one frame. Had to reduce that detection.
