That's the nice thing about solar viewing in H-a. Even between solar max periods, when there isn't a sunspot to be seen in white light, there is still plenty of detail visible for the narrowband observer. Not as much, but there's usually something to see. On Sun, Mar 9, 2014 at 9:29 PM, Wiggins Patrick <paw@getbeehive.net> wrote:
Doesn't look great for solar observing.
