Yet another image found in my archives.

Rosette nebula in both HOO and SHO, Feb 2022.

While backing up some data I found a few images in my archive that needed processing. Not the best shots, but I managed to get something out of it. This is from Dec 2022, 7 hours total exposure in narrowband (SHO + a colourised HSO to emulate natural colours).

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.

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.

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.

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.
