I’ve managed to piece together a pretty nice setup for observing the Sun in hyrogen alpha light. It doesn’t work quite as well for photography, but I managed to grab the image below today. The H-alpha filter is a 75mm Lunt Solar Systems double stack with a 0.05 nm bandpass. This narrow bandpass really brings out the granulation on the surface compared to the wider single stack bandpass that shows primarily prominices. Next time out, I’ll grab a pair of photos to illustrate the difference between the single stack (0.07nm) bandpass and the double stack bandpass. The filter was attached to a TeleVue NP101is.
