I was wondering before spending time and money looking for suitable offer from refurbished market if Asahi Linux should run both... Source: about 1 year ago

Subs were calibrated and integrated for each filter using SiriL. In PixInsight I started by cropping the three stacked images, used automatic background extraction, and then combined the three into a colour image. BlurXTerminator on the combined image and StarNet v2 to separate the stars.. Separate multi scale linear transform on starless and luminance, more aggressive on the starless image.
