About this image

Captured over several sessions from 26 September to 9 October using Sequence Generator Pro. 26 September saw my best guiding graph to date indicating a night of very good seeing. Used quite a few of the goodies in the Pixinsight toolkit on this image. This is just the Ha data; colour being posted next. Also hoping to get subs in OIII and SII for a tricolour narrowband.
