Description

This is my first attempt at a mosaic, a two frame attempt taken from my backyard.

I have always admired this region and it's a nice feeling to have captured it.

This mosaic is approx 2.23 Gb due to the high resolution of the image from the QHY600.

Images were taken over 5 nights where the skies were clear at various times between 17 April and 26 April 2020.
