I don't use anything, generally. There's a BlurXterminator plug-in in PixInsight I use for deep-space astro shots, but in general I try keeping the ISO setting low to prevent noise from being generated in the first place - it's a relic from my film days, I guess.
Dunno if this will work, but there's an RW2 file here:

I'm sure the high ISO number contributed, given how clear the pre-totality ISO 100 shots look, but on the other hand the Read Noise in the S5's sensor is pretty low at anything above ISO 600 or so, ...
This was taken from the Photons to Photos website's archive.
Also, between the shutter speeds I was using and the ambient temperature ("Brisk" would be an apt description), I don't believe my problem was thermal noise. I doubt the sensor had any time to heat up, even shooting at 1/5th of a second.
[*shrug*] I'm still pretty chuffed with what I got, all things considered. And I've got 5-6 years to think about how I'd do the next one differently. Your shots are impressive, so much so that I just swooped a mint-ish Tamron 55BB and a K&F Concept L-mount adaptor for myself off eBay last night. It could be the best $150 astro lens I've ever seen.
