The problem (I feel) with my edit is that I still have too few subs to properly get rid of satellite trails. Same issue with an image I shot of the Witch Head Nebula. The Orion area is a pain due to the geostationary satellites all passing by continuously.
Witch head nebula in LRGB Zoomed in version of the Witch Head which shows a remnant of red green and blue streaks, where geostationary satellites moved through the frame

The Relativistic Jet of Quasar 3C 273 - From Rolf Wahl Olsen - https://flic.kr/p/2neFEQV
The bright quasar 3C 273 has a large jet that is visible in optical light, extending some 200,000 light years from the quasar itself. At 3C 273's great distance of over 2 billion light years the jet appears only 23 arc-seconds long in the sky, extending towards the SW. To the left is a comparison with an image form the Hubble Space Telescope, showing the jet in high resolution and revealing its detailed structure. Click here to see the spectrum of 3C 273 captured with a simple diffraction grating, and its red-shift and distance calculated using the Hydrogen emission lines. Image details: Date: 10th April 2022 Exposure: Luminance 24x300s, 2 hours @ -25C Telescope: Homebuilt 12.5" f/4 Serrurier Truss Newtonian Camera: QSI 683wsg with Lodestar guider Filters: Astrodon LRGB E-Series Gen 2 Taken from my observatory in Auckland, New Zealand

You don't just take a single photo of the moon. You take a video then stack the best frames to try to eliminate atmospheric distortion.

I took 3min videos, which was about 20gb, then stack the top 20%. Do that for all 4 LRGB filters (sane people use a colour camera).

Then sharpen and combine

Decided to try reshooting the moon last night, this time in LRGB.
Muuuch better.

The Heart of the Lobster: Pismis 24 and NGC 6357 - From Rolf Wahl Olsen - https://flic.kr/p/2na9VH5
This image is a high resolution narrowband close-up on Pismis 24 in the centre of the large nebula NGC 6357, also known as the 'Lobster' or 'War and Peace' nebula. The cluster and nebula lies 8000 light years away towards the constellation Scorpius. In traditional RGB images this nebula appears intensely red with little colour variation (likely reddened by interstellar dust). But with data gathered in the specific emission bands of H-Alpha and Oxygen III the nebula takes on a much more colourful appearance. In addition, the image has been enhanced with broadband LRGB data to bring out more stars and their colours. At the very centre of the nebula is a somewhat hollow cavity, home to the star cluster Pismis 24 containing some of the heaviest stars known. The intense ultraviolet radiation from these stars is slowly eroding the surrounding gas and dust away and shaping the delicate structures visible throughout the region. The heaviest of these stars, designated Pismis 24-1, was long thought to weigh some 200 to 300 solar masses, well in excess of the theoretical upper mass limit of about 150 solar masses for an individual star. But in 2006 high-resolution images taken with the Hubble Space Telescope showed that Pismis 24-1 is really two stars orbiting one another. Further to this, ground-based spectroscopic studies have revealed one of the stars to be yet a further tight binary. Still, these three stars are among the heaviest known in the Universe.

Ptolemy's Cluster - Messier 7 - From Rolf Wahl Olsen - https://flic.kr/p/cNMYiy
This image shows Ptolemy's Cluster, a very bright open star cluster easily visible with the naked eye near the tail of Scorpius. It lies at a distance of 980 light years and has some 80 member stars within its diameter of about 25 light years. The age of these young bright stars is approximately 200 million years. The cluster was known as a hazy patch in the sky already in antiquity and was first described by the ancient astronomer Ptolemy in 130 AD. This image was taken with a bright 78% illuminated Moon nearby. Image details: Date: 31st May 2012 Exposure: LRGB: 48:24:24:24m, total 2hrs @ -28C Telescope: 10" Serrurier Truss Newtonian f/5 Camera: QSI 683wsg with Lodestar guider Filters: Astrodon LRGB E-Series Gen 2 Taken from my observatory in Auckland, New Zealand
