Details:
We had an opportunity to image the Sun and active region 2436 through a 130mm refractor, 0.3 angstrom h-alpha filter and ZWO color video camera. Using a Baader TZ4 telecentric lens system, it took 27 individual videos to capture the entire surface. 27 images were then composited manually in Photoshop.
