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).

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 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...

Mars getting smaller, a few weeks after its opposition.

Another attempt at Mars, as it's getting far away from us, and visibly smaller.

Images taken with my SkyMax 180 and ASI178MM with RGB filters.

A couple of close up of the Moon, around the craters Copernicus and Plato.

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

Nearby is also visible the crater Eratosthenes.

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.

The Red Planets a few days before its 2020 opposition, one of the closest in years.

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

Jupiter, a few weeks after its 2020 opposition.

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.
