This was my final two nights in Perth Before getting on the plane to NZ. The Antares area or Rho Ophiuchi two nights. I was doing the Milky way panorama so this could rise up. The camera was rotated to get the dark rivers in the full photo A far cry from the original photo I took in may 2019.

After a year of equipment problems mainly around the focused and software issues, my rig is set for its first test run. On the HEQ5-pro mount is a Skywatcher 120-ED, Primalucelab Eagle2 computer and ESSATO focuser coupled to an Atik 314L+ on the camera train. Hopefully if the nights ever go clear I can really start to use it all properly.

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 !

This beautiful comet is gone now, this may be one of my best shot of it as it was in its full glory!

Actually it was still getting closer to Earth but slightly fading. A slight green color started to appear around the nucleus. This can be noticed on this picture.

Shot with Nikon D7500 and Sigma 100-400. I stacked a few pictures tracked with Skywatcher Staradventurer.

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.....

Nel buio del cosmo, brilla il sovrano degli dèi: Giove, il colosso celeste. Come il mitico Iuppiter dominava l’Olimpo con il fulmine in pugno, così il pianeta più grande regna nel nostro Sistema Solare. La sua immensa gravità protegge la Terra da comete ed asteroidi, proprio come il padre degli dèi manteneva l’ordine tra uomini e divinità.

Osservarlo è come scrutare l’antico volto del mito, impresso nel cielo.

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.

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 Heart Nebula is an emission nebula located in the constellation of Cassiopeia, around 7,500 light years away from Earth and have a radius around 165 light years.

The term ’emission’ means that the cosmic gas that forms the nebula is actually glowing itself.

Over the years IC 1805 has been designated as the ‘Heart Nebula’ due to its resemblance to the shape of a human heart.

The glow of the nebula comes from the radiation of a small open cluster of stars known as Melotte 15.

The cluster contains very young, blue, hot supergiant stars that are about 1.5 million years old and is located near the nebula’s centre. Some of this stars are about 50 times as massive as our own Sun.

The stars of Melotte 15 are blasting the surrounding hydrogen and causing it to emit light, powering the Heart Nebula’s beautiful glow.

The third attempt was the good one. Stars were weird/pinched on the first sessions (Redcat Focuser Issue).

So for the last clear night of november I decided to go back on this nebula to break the spell. :p

I've shoot from 7.00 PM to 6.00 AM, resulting in around 9.5 hours of good subs (10 min each)

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

NGC 2359 - Thor's Helmet is an emission nebula in the constellation Canis Major. The nebula is approximately 11.96 thousand light years away from Earth and 30 light-years in size.

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.

The Lagoon Nebula (M8), is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula.

This is the latest version of the Lagoon Nebula, is another re-process of the image taken 17/07/2020 from my house in Melbourne. This is 20 x 3 min Ha, 30 x 3min Sii and 28 X 3min OIII sub frames with dark, flat and bias frame subtraction. It was captured at 0'c using the SBIG ST2000xm on an 8" carbon fibre Newtonian reflector on a Skywatcher NEQ6 mount.

IC1396 featuring the Elephant Trunk nebula. Shot using Ha and Oiii filters on completely stock Canon DSLRs.

This was first light on my new setup. Totally new everything aside from camera. I upgraded from a Star Adventurer to an EQ6R-Pro which was a definite learning curve. The first few nights were super frustrating, I just couldn't get anything to work and it felt so inconsistent and like I was never going to get an image.

I also am currently using a Canon 400mm 2.8 IS III, which is just awesome.

Overall I'm really loving this setup, it's incredible to use and so nice to be able to remote operate it.

Serra Negra ( Bortle 4) /São Paulo/Brasil . 05/2022

Polaris is a star in the northern circumpolar constellation of Ursa Minor and is commonly called the North Star or Pole Star.

With an apparent magnitude of around 2, it is the brightest star in the constellation and is readily visible to the naked eye at night.

The position of the star lies less than 1° away from the north celestial pole, making it the current northern pole star.

The stable position of the star in the Northern Sky makes it useful for astrophotographer in the Northern hemisphere to align our telescopes with the central axis of the Earth. [Wiki]

Imaged over 11 nights in June and July 2024 while waiting for my main target to reach altitude.

I have always wanted to capture the IFN (Integrated Flux Nebula) around our pole star in the Northern hemisphere.

I thought that while I am waiting for my main target to rise in altitude, just sitting on Polaris would be a cool idea.

The main problem is guiding your telescope at the pole. In the end none of the frames were guided, Plate solving was interesting too. I attempted to centre the star but the mount would never end up plate solved and locked on. The solution was to place Polaris off centre. The result was that I obtained a better view of the IFN surrounding the star.

735 x 2 minute images were originally taken without a filter and reduced down to the best 349. This left me with over 11 hours of the best frames to process.

I am very pleased with my first attempt. I must look at either making a mosaic or using a wider FOV telescope to feature more of the surrounding space dust.

A higher resolution image with imaging details can be found on my Astrobin page at: astrob.in/fdzm9m/0/

Thank you for looking.
