Astroselfie in the garden of peace. I took advantage of the clear skies, which have been rare this year, and cycled to take some pictures of space and galaxies by the lake. Despite the near full moon and city light pollution. A great expedition!

The ISS flies at an average altitude of 400 kilometres (248 miles) above Earth, circling the globe every 90 minutes at a speed of about 28,000 km/h (17,500 mph).

Did you know that over 20 dwarf galaxies circulate

Did you know that over 20 dwarf galaxies circulate our home galaxy, the Milky Way? This is one of those dwarf galaxies, the Large Magellanic Cloud. It is 12 times larger in the night sky than the full moon - you just have to be in a dark enough place to see it, or you'll need to cut through the light pollution by collecting enough data with a camera, like I did.

I took this photo from my balcony… Swipe right twice to see what the sky looks like above the city of Canberra with a 1 minute exposure. With my own eyes I only saw a few dim stars. To make the galaxy visible, I took 28 exposures and stacked them together. After some adjustments in Darktable, I was able to get a decent final image, given the conditions. Swipe right once to see the image before edits (after processing in APP).

‘Connection’. I was amazed how much difference lower levels of light pollution can make, being used to the bortle 6-7 city lights. Photographed 2021-04-20 under the bortle 4 skies of #Katoomba in the #BlueMountains #Australia. It only took me one 10s frame at ISO 3200 and f3.5 to get enough data for this. Edits done in Darktable to bring out the features of our beautiful galaxy.

Decided to process this one a bit further to remove some of the light pollution. Turned out quite nicely I think. 🙂

I collected the data for this a while back and finally got around to analysing it. Collected 12 Oct 2020 in Canberra, Australia, under bortle 6-7 light polluted skies. You can actually see some of the light pollution haze in the lower part of the image.

Jupiter and Saturn are conjoining. On the 21st they will appear to collide from Earth’s perspective, so heads up and clear skies! I took this on the 18th of December 2020. Three moons of Jupiter can be seen (left to right: Europa, Io, Callisto), and one of Saturn (Titan).

Unguided. Settings: f5.6, 1/1.3s, ISO 1600. [Focal Length, Aperture, Shutter speed, Sensitivity]. Frames: 100 x light, 20 x dark, bias, flat & dark flat each. APP used for stacking, cropping, and removing light pollution gradients. Darktable used for curves adjustment, lens correction, denoising, and cropping.

[Swipe!] This widefield of space in the Pavo const

[Swipe!] This widefield of space in the Pavo constellation reveals the depth and age of our universe. There are several galaxies in this picture, the most prominent of which is the NGC 6744 on the left. It is a spiral galaxy like our own Milky Way, and it took light 30 million years to travel from that galaxy to my camera sensor.

The Pavo globular cluster (NGC 6752) on the right is much closer to us, in fact it is roughly half-way between us (13,000 ly to us) and our galactic centre (17,000 ly to the centre). This cluster of gravitationally bound stars is 11.78 billion years old, almost as old as the universe itself.

I used the MSM tracker and a 135mm lens on f2, ISO 100, to take 10 x 1min and 28 x 30s exposures, which I stacked using AstroPixelProcessor (APP). The final exposure time totalled 24 minutes. I also used the APP software to control light pollution, along with using a light pollution filter on the lens.

Edits: APP - Initial stretch, calibrated star colours. Darktable - Curves, highlights, shadows adjustments, noise reduction, lens correction. GIMP - For the close-up of the NGC 6744 I used GIMP to brighten up the galaxy so that it can be seen a bit better, while also reducing red noise in the background.
