Great to hear Peter!
That's fine result too for someone just getting started with a new tool!
Though there are a few ways to add Ha to a visual spectrum image (much depends on the object and depth of your Ha data), ST 1.8 alphas come with a dedicated module for the most laborious/difficult case; adding narrowband
accents (
docs being built here). The latter is particularly useful for galaxies such as these, which are typically poor in Ha signal,
except for some very high signal stellar nursery areas.
Thanks Martin, also, for offering help and support.
Clear skies!
