A first glimpse of comet C/2023 A3 (Tsuchinshan–ATLAS) from Box Hill.

Not terrible, considering I forgot my tripod home 🤦

Stacked 4 shots of 1/10th of seconds each, handheld

After missing it the first time, the Aurora came back, visible even here in southern England.

I managed to grab an almost night long timelapse, with a few selected highlights.

I used the "revisions" mechanism to upload 3 different frames, but please check out the [url=https://www.youtube.com/watch?v=4Z3GD9sv2nc]full timelapse[/url] as well.

Planetary season is starting again, and I got a new ASI678MC for the occasion.

Bit of a rushed shot, but quite happy about the results, given the planet wasn't too high yet, and seeing was terrible (as usual)

I also did a bit of Saturn during the same night, but it wasn't worth publishing.

The Sun in H-Alpha

First light for my new C11.

Really bad seeing, and still a lot to optimize and learn about my new setup, but it's already quite promising.

First light for my new C11. Really terrible seeing, and lots of things to still learn, but already much better results than my old C7 Mak.

Weather was mostly cloudy or veiled, but I managed to get a few clean frames between the clouds

IC 1396 in narrowband from London.

Shot over three nights in August, September and October, with almost 19 hours of acquisition. First light for both my new ASI2600MM and Chroma narrowband filters.

Postprocessing using three different palettes: SHO (classic "Hubble palette", with more contrast), HOO (using only oxygen and hydrogen filters, more realistic colours), and HOS (middleground between the two).

This sequence was shot over 3.5 hours to try and capture Jupiter's rotation as smoothly as possible. Seeing was fairly bad, but that's quite standard around here. I also changed the camera to the ASI183MM Pro, cooled down to -15 degrees to try and minimize noise.

You can also see two satellites eclipsed: at the beginning of the animation Io disappears behind the Gas Giant, while at the end Europa suddenly reappears leaving the planet shadow.

In this second version the animation is a lot more fluid, but at the expense of some detail loss.

Jupiter, a few weeks after its 2022 opposition.

The Great Orion Nebula, M42, in narrowband. Two processing versions, using HOO palette (more natural looking) and SHO (more detailed, as it also includes Sulfur).

First proper attempt at narrowband imaging and processing.
This started mostly just as a test session, since the first part of the night was cursed with passing clouds right in front of my target. I also had some problems with the autofocuser (that just stopped working at some point), and balancing issues.
All things considered, not too bad...
