Description

This trio of galaxies in Leo is one of the very first targets that I ever imaged digitally, back in the spring of 2017. It is also a target that I come back to now and then, partly to compare where I’m going to where I’ve been, and partly because it’s just a beautiful patch of sky.
The data for this image was collected in January 2022 from Pinnacles National Park, but I was never too happy with the processing. Some high haze was present, which caused halos around the brighter stars, which I struggled to remove for a while – then I just accepted it and made it into a feature of the image, instead of a bug.
This is also my first attempt at using Russ Croman’s extraordinary NoiseXTerminator tool for noise reduction in PixInsight.
