AR1967 Heads Over Horizon

I did not have a chance this week with the weather (freezing and overcast) to see the large sunspot complex AR-1967 until today. It is now about gone over the horizon of the solar disk. The images below are taken with a Lunt LS60T/PS Hydrogen-Alpha solar telescope and an Imaging Systems DMK41 monochromatic video camera.  The first image was created from movie frames at a single exposure. The second image was composited from frames of two exposures, short exposures for the solar disk and longer exposures to capture the details in the solar prominences.
