Description

A second night trying out image stacking with a camera on a fixed tripod. Used the 24mm f2.8 AIS Nikkor again and this time it was 150 exposures of 15 seconds each at 1600 ISO. I continue to be impressed by the little FujiFilm X-A3; for an un-modded camera it does a great job of picking up H-alpha, as shown by the presence of the California Nebula in the very top right corner.

Stacking, light pollution reduction, and star colour correction done in Astro Pixel Processor.

Further enhancement in StarTools using Life (Less=More) and Colour (saturation increase and slight red boost), before 50% binning.

Additional enhancement in PS 2015 then a final tweak and crop on my phone in Apple’s Photos app.
