Description

Imaged over three nights with close to a full moon and sever gradients especially the last night. I processed and reprocessed several times disregarding and including various nights. I imaged for a total of 12 hours, but honestly don't remember how many hours was included in this 'final' image! 😃🤔
I will for sure revisit the Jelly fish next year!

Title: Restack and reprocess

Description: Carefully selecting subframes and omitting frames suffering from gradients and high thin clouds. Restack and reprocess with some improved skills since last revision. Also included Topaz Denoise AI in the workflow. Hints on how to deal with the horrible halos of Propus and Tejat are most welcome! Also found that latest version of StarXterminator does a better job of removing stars.
