The solar surface is  dominated by 2 very active regions, AR12598 in the northern hemisphere and AR12599 in the south.  Several small prominences show up along the E-limb, and 2 larger ones show up on the west.
The close-up near white-light images are captured after shutting off the power to the oven of the filter.

Telescope: AP Starfire EDT 155 mm f/9.
stopped to 50 mm for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: Imperx 4M15
North is up, and east to the left.
