Difficult object to capture "properly" in narrowband only, as it's both an emission and reflection nebula, and the OIII data is almost non existant.

I managed to get enough OIII data to somewhat highlight the areas that would be part of the reflection nebula (and even then, the OIII data is stretched to the limit).

Shot between the 3rd and the 9th of January 2025.
Palette: HSS, with OIII added in a second stage with a blue-ish tint.

Another shot from 2022

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).

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)

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.

This new 2024 version, aside from using new modern tools such as BlurXterminator and NoiseXterminator, makes use of a different technique illustrated by Adam Block.
The image was first rendered with an HOO palette, then SII data was added back with a yellow tint.

I really like this new output, the colours are quite rich and well balanced, especially compared to the older HOO and SHO versions.

The other (older) versions were processed 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 an eclipse of the moon Europa: at the beginning of the animation it disappears behind the Gas Giant, suddenly reappearing at the end of the video after leaving the planet shadow.

A better version of both videos can be found in my website: [url=https://gulinux.net/blog/2022-10-10-jupiter-animation-with-europa-eclipse]gulinux.net[/url]

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...
I processed the image in both HOO palette (more natural looking) and SHO.

California nebula under London Sky.

Conditions weren't exactly ideal: light pollution, obviously, then clouds rolled in just when I was ready to start my sequence, shortening capture time by a couple of hours.

Also, the nearly full moon was very close to the target, causing some nasty reflections on the (now cropped out) border of the image.

Overall I'm quite satisfied by the result though, the Optolong L-Enhance filter seems to be doing a really great job.

The target of the month, in two versions: a RGB combination (left), and with an IR-pass filter (right).

Finally got a decent night for imaging Jupiter and Saturn, very low here in the UK (just around 15 degrees above the horizon).

Seeing was terrible, but I'm still relatively satisfied with the results, given how difficult these planets are this year from this latitude.

Given the unusual stride of sunny days and clear nights, and the lockdown in force, forcing me to stay indoors instead of searching for dark places, but also offering more time for imaging at the same time, I decided to take a few steps in doing more "garden astrophotography".

This is my first experiment with some new equipment: an Optolong L-Enhance narrowband filter, and a iOptron CEM40. The first allows me to image many targets even from heavily light polluted skies (here in London, Bortle 8 or 9), the latter allows for longer exposures, a necessity using narrowband.

Detail of the Small Magellanic Cloud. (NGC 346 and 371 among others)

Wide field shot of the Milky Way around Aquila. Altair is clearly visible in the field.

A first test for my new ASI 1600mm.

This camera has bigger pixels and a larger sensor than my other camera, the ASI 178mm, so it's more suitable for deep sky imaging rather than planetary shots.

But with such large field of view I can get a picture of the moon without having to stich it.

Composite shot of 78 images.

For each image I stacked 300 frames (out of 500).

A bit noisier than I would have hoped for, but given the terrible weather this winter I didn't manage to get enough frames for a better picture (barely 3 and a half hours in total).

Still, not a terrible picture either.

The region around Deneb and Sadr, in the Cygnus constellation.

Full of stars and nebulosity, given it's special position in the middle of the Milky Way, this picture features many of them, like the North America, Pelican, Gamma Cyg Nebula, Crescent.

Probably my last shot of Saturn for this year, already very low above London sky.

This is my first attempt at colour images using a RGB filters set.

Seeing mediocre/low.

Blog article: [url=http://blog.gulinux.net/blog/2016-08-10-teeny-tiny-saturn]http://blog.gulinux.net/blog/2016-08-10-teeny-tiny-saturn[/url]

First shot of Mars, close to 2016 opposition.

Mediocre seeing, I used infrared pass filter instead of the usual IR blocking, to enhance details and block out most of the atmospheric turbulence.

I also used an extender with my 2.5 barlow to increase focal length up to over 7000mm.

While targeting Mars, I was also able to try a few shots on Jupiter.

Seeing wasn't too good, so the image resolution is not great, but the Great Red Spot is clearly visible, as well as Europa just passing in front of Jupiter's disk.

Satellites in order, from left: Io, Europa, Ganimede

A first glimpse on Saturn, waiiting for the next opposition. Seeing was very good.

Red spot visible

Jupiter shot from home, average/bad seeing conditions (but luckly not so bad), quite low on the horizon (less than 20°).

Infrared filter to block most of the atmospheric turbulence.

Moon, the area around Plato crater (the biggest in this image, with an "ear" to its right).

Above it, slightly to the left, there's Cassini, a medium sized crater with two smaller craters inside (Cassini A and B).

Separating the two, the Montes Alpes, with the Vallis Alpes within, then Mont Blanc.

To the far left, another two big craters, Aristotelest (the biggest) and Eudoxus.

To the top/right, the vast plain of Mare Imbrium.

Moon, Copernicus crater, one of the most prominent of our satellite.

Nearby is also visible the crater Eratosthenes.

Shot with my SkyMax 180, ASI 178MM

This composition of multiple shots was taken with my usual planetary camera, after testing the newer one.

The smaller pixels allow to resolve much more details than the previous image, and the higher resulting speed also helps in getting more frames for stacking.

A few areas are a bit ruined due to the stiching process, I hope to be able to reprocess this in the future.
