NGC281 Pacman Nebula in SHO

[fireballxl5]

My latest process is of some narrowband data from last winter (collected over the 2020 Christmas break) of NGC281, the Pacman Nebula in Cassiopeia. This false colour version uses around 20 hours of Ha as well as roughly 5 hours each of Oxygen III and Sulphur II, blended using the standard SHO Hubble palette in PixInsight.

Captured using my dual-scope rig (150mm & 85mm refractors) at an image scale of 1.7"/pix. Total 186x600s, so 31 hours, chomp chomp😆

Very nice, colour and detail, 31 hours is a lot

Thanks, appreciate the comments🙂

As both scopes have Ha filters it seems easy to accumulate this channel quickly when the moon is about as this is usually when it's clear🤨 Surprisingly for me, this data was collected over just 3 nights within the space of a week.
