Catching up on Andor Season 1 so I can watch Season 2. I am showing my age as I saw Star Wars Episode 4 in cinemas in 1977 and I recognise the nav prop in Andor episode 6 as an old pop up polaroid camera.

Up and imaging tonight on NGC4303 and Sh2-60. I had the scope out the back and was ready to go, but the rain warning app on my phone went off. The Royal Australian Air Force is playing again, and it was just chaff clouds. #Astrophotography

47 Tucanae is a Globular Cluster located 4450 Ly from Earth. I captured it in June 2023 using my 800mm reflector telescope. It’s one of the brightest globular clusters in the night sky, second only to Omega Centauri. It contains millions of stars and has a particularly dense and bright core.

Its clear and I am capturing data on Messier 100. Battling some pretty variable seeing at the moment due to a strong jet stream. Lots of automatic refocuses going on but to be expected as this target only gets to a max of 42 deg above the horizon so I am shooting through a lot of atmosphere as well.

This nebula region is in the constellation of Vela and is about 5500 light years from Earth. The bright nebulas in the bottom right and upper left of the image are active star-forming regions. Captured with my 360mm telescope from my backyard in Brisbane, Australia.

This is Messier 33, the Triangulum Galaxy, which is 2.7 million light years away from us. I captured this data in 2022, but my processing skills weren't up to the task of getting a decent image out of it then. My skills and the tools are better now so I have been able to produce this image.

Messier 16 with the famous Pillars of Creation at the nebula's centre. Located in the constellation Serpens, it’s a vast emission nebula where freshly formed stars illuminate and interact with surrounding clouds of gas and dust. Imaged from my backyard in 2023 using an 800mm reflector telescope.

This image is IC4685, a nebula complex that I photographed back in 2023 from my backyard in Brisbane, Australia. It is located in the constellation of Sagittarius and is about 4100 light years from Earth. A striking feature to highlight is a dark “river” that crosses the central emission region.

RCW 32, also known as Gum 15, is an emission nebula located in the constellation Vela. It is part of a larger HII region and is illuminated by the bright star HD 74804, which plays a key role in ionizing the surrounding gas. Imaged from my backyard in Brisbane in early April 2025.

This is the dark nebula Barnard 312 located in the constellation Scutum. Dark nebulae like Barnard 312 are regions of interstellar dust and gas that block the light from stars and other objects behind them, creating striking silhouettes against the brighter background of the Milky Way.
