Prominence visible this morning through LS100THa SS scope. Changes were visible in minutes, and images show change after half hour. Taken with 2x barlow and ASI174mm. Visually at 150x, a lot of intricate detail was visible, and through doublestack the base of the prom and the edge of one of the streamers became brighter than the rest of the prom as I tuned the pressure tuner inwards from the on band position, showing the doppler effect of moving material.
