Details:
Seeing conditions were excellent to view and image these active regions today so I decided to image them in all three frequencies (using a ZWO ASI 174MM CMOS camera):
1) White light: Astro-Tech AT130 EDT f/7 with Baader Astro-Solar film
2) Hydrogen-alpha: Lunt LS80THa DS
3) Ionized Calcium line: William Optics Zenithstar 70mm f/6.2 with Lunt Calcium-K module
500 frames / gain: 120
