Active Region AR2733 is about to rotate off the Earth-facing side of the sun.
Below is an image taken using a Coronado 60mm external Etalon fitted to the Takahashi FS-60C scope + the CQ 1.7x module (FL=600mm), then a 2.5x Tele Vue Powermate Barlow was added (FL=1500mm). A 30mm Blocking filter and the ZWO ASI174 video camera were used to capture the image. The image is shown in inverse and in B&W.
