I’ve been amazed at the length and consequent detail of the Helix’s put up here so I apologize that this is only 10 hours and somewhat noisy. I’ve tried to pull out some detail and keep the O3 represented and added some RGB stars. All a bit of a compromise with limited data I guess. Appreciate any and all advice/comments.
