So, I was doing some testing between 8 bit and 16 bit mono, as well as bewteen avi and ser in bit (surprise, 16bit ser is the best by a wide margin), but unfortunately my last test capture before going for the time lapse was the 8 bit ser video, so this time lapse is also unfortunately only in 8 bit, which caused a sizeable loss in detail as well as some crazy gradients in the background. Lesson learned, always double check your settings before starting a project, lol. Seeing had degraded by the time I was done with test and single image captures, so the finer details were kind of doomed anyways.
The small active region was the only semi-bright spot I could see on the main disc of the sun, with a small possible spot forming maybe?
