IC 443 Jellyfish Nebula

South Coast, UK

Here is IC 443 Jellyfish Nebula - March 2025

This was taken in the New Forest, South Coast, UK.

I used the Standard (non-mosaic) mode, with Dither.

It was clear well above the horizon, misty lower down, not windy, no moon, countryside Bortle 4 skies, around 7° C, 90% humidity.
All my equipment was very wet. The Vespera II auto heater kept the lens completely clear.

I saved the FITS and processed all of them in Siril until stretched, then GraXpert to Denoise, final tweaks in Affinity.
