With little chance of any clear night skies in Sydney for at least the next week I've resorted to having a go at processing some previously taken data that I didn't have much hopes for.

This is the Helix Nebula, NGC 7293. While it's big as far as planetary nebulae go it's still a rather small target for a Seestar S30 Pro, and I also didn't have as much data as I would have liked (408 30 second exposures from two nights), so I really threw everything I could at it when it comes to processing.

Drizzle with a 1.5× upsampling in Siril, SyQon Parallax and Prism (free Nano versions) for sharpening and denoising, and Veralux Nox, HyperMetric Stretch & Revela for residual background removal, dynamic range compression and local contrast enhancement. I'm honestly amazed it came out this well, but think all the credit should go to the seriously impressive free software I used to do it.
