I've have an Seestar S50 from Octomber 2025. With software version 2.6.1 and 2.6.4 everything gone ok. With latest 3.0.0 and 3.0.1 I have this gradient problem and high rotation field even at 20 or 30 degree altitude. On 2.6.1 and 2.6.4 rotation field was very small but now at stacking individual frames throws out objects from frame. I wrote the problem also on ZWO Official FB group and I wrote down here. I put it another scope side by side to see if the problem persist on the second smart telescope but other producer, no gradients, image cristal clear. The sky was cristal clear.
I've checked also DBE mode on auto at Preview and DBE on processing after stacking the individual frames. Same problem. DBE option does not remove the gradients and neither AI denoise. If in Octomber and November I've captured from Bortle 6-7 very good images and also published on Vega Magazine, a Magazine made by Bucharest Astroclub, now everything is a totally mess.
