I reprocessed this image of Saturn which was taken on the 25th of January this year.
I'd been imaging for less than a month at the time and had very little experience using Registax so the original picture wasn't the best.
Again I used Registax, 238 frames stacked, adjusting up to 49.5 in level 5 in wavelets and going heavy on the gamma. Then finally using Astro USM in Irfanview.
I've also included the best frame that Registax had to work with.
