Part of an HII (ionized Hydrogen) region in Cassiopeia the Pacman Nebula is a bright emission nebula.
Named for its resemblance to the video game character the nebula lies at a distance of around 9500 light years from earth.
This image captured in narrowband Ha light was acquired over 2 nights - 17 & 18th September in strong moonlight. After a prolonged period (seemingly never-ending!) of poor skies was glad to be out imaging again!
Hopefully will have some OIII and SII to add later.

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.

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.....

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!

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.

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.

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.

My first try with the new chip that was put in the camera to replace the broken usb.
I was sent a QHY183M mono chip not the QHY183C Colour chip caused all sorts of problems in the end this camera getting found is now know as QHY183M but takes coloured photos. I lost a whole lot of time with the camera Changes and setting up. This is in effect only 33 shots But happy the way it came out.

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

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.

The Eagle Nebula (Messier 16 or M16) is nebulosity surrounding a young open cluster of stars in the constellation Serpens. The dark center of the nebula was made famous as the "Pillars of Creation" when imaged by the Hubble Space Telescope. It is approximately 5700 light years from Earth.

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.

First Look at the NEQ6 pro, this is 44 shot on the only night in lock down to be able to shoot now its back into rain and clouds.
44 Shots 10min each till the tree got in the way and clouds came over in the early hours of the morning.. when you see the number of stars in this one shot really puts thing into perspective.

This is a second look at this Nebula with a whole new Camera QHY183C a replacement for the ZWOASI183MC that was faulty. I could focus automatically with this camera hence the detail in the eye is much better than the first one with the ZWO. This camera took a bit to get use to as I had to change wires and ports on the computer to get this to run and download photos.

I grabbed this shot on the evening of 5/15, through some surprisingly thick high-level clouds just about a minute before it entered totality. The clouds resulted in a neat aura/halo effect in the photo.
I'm just thankful to have gotten anything since we were surrounded by storms at that moment. Distant lightning was lighting up the upper atmosphere as I snapped this shot from my front yard. I hope you enjoy!
