Description

This is my first attempt at creating a mosaic and was more of a proof-of-concept experiment than an attempt to create a high quality image. As it turns out, there are certainly artefacts and issues with it that I will learn to address, but I am very happy with the overall result. First mosaic, only an hour of integration, from my backyard (well, even better--inside nice and warm with my rig outside at -15C!)

4 panels each with 30x120s, MosaicbyCoordinates then GradientMergeMosaic then basic processing, nothing fancy, so basically one hour integration.

Biggest challenge: NINA and I didn't get the overlap/pointing tolerance quite right, so the initial mosaic had a gap. My first try I had the rotation a bit off too, but there was no gap, so I used the data from that one to fill in the gap of the second one. I think I know how to avoid this issue in the future--time will tell!

Description: cleaned up some artefacts, reduced stars a bit more selectively; still not really happy with colour of stars or the galaxy. I'll definitely be back for more and better data--too nice a subject to leave like this!
