Thanks for the repost Rami!

I'm pretty sure (like a few others here) these are mammatus, with parts blown into streaks by strong winds towards the camera along the underside of the cumulonimbus anvil. They're in an odd perspective with the good mammatus structure far away and silhouetted against the brighter sky. Nice pic!

Images are red filter only, calibrated to be similar in brightness, moons labelled. The line across Saturn is the rings/silhouetted against the planet. F ring would normally be totally invisible, may be brightest part of the rings in images at/just before before equinox. Celestron C14, ZWO ASI585MM.

Thanks Rami! Those colours are pretty but a nightmare, some of the belts appear actually slightly greenish (and did last year), but normally green isn't seen much in the sky - adjusting this image wasn't easy and i still don't think I have it right 😬

Indeed - it is significantly easier to catch Mimas, and perhaps even fainter moons just now without the rings glare. It should also be easier throughout this opposition as the rings will be a bit fainter.
