Скачать или смотреть The Giant Squid - Full HOO Processing Tutorial In PixInsight (Mono)

Squid Nebula (Ou4) is one of those targets that looks unreal the first time you see it — and it’s also one of the easiest ways to get humbled by faint signal and gradients.

In this processing video, I take you from stacked data to a finished image of the Squid Nebula in the HOO palette (Hydrogen-Alpha + Oxygen-III). You’ll see the full workflow I use to bring out the delicate OIII “tentacles,” control noise, protect star color, and keep the background clean without crushing the faint outer structure.

What’s covered in this edit:
• HOO combination (Ha + OIII) and color mapping choices
• Stretching strategy for faint OIII signal
• Noise reduction without destroying nebulosity
• Contrast enhancement and local detail (without overcooking it)
• Star handling: star reduction, star color protection, and recombination
• Final color balance and finishing passes

If you’ve ever struggled with weak OIII data or ended up with a cyan mess and gray stars, this one is for you.
