About this image

This is the stitch of 6 mosaic tiles captured over 3 sessions between 22 and 02:45 UTC Each session capturing the 6 tiles approx 16x120s. In Siril / SyQon I have used "soft" settings so avoid loss of faint detail in outer rings. Stretched and recompiled with Veralux, colour fine tuning with Affinity photo. Compensation for differences in background gradient between tiles came with some trial and error across multiple gradient removal tools
