H-alpha Sun – October 4, 2016

Scroll down to content

A new interesting active region is coming. Hope to get a better glimpse in the next few days.

For now, just one shot under very poor seeing and wind. Perhaps my worst H-alpha image until now…

150mm F/8 refractor, Quark chromosphere, 0.5x reducer, ASI 174MM. 500 frames out of 5000. Seeing 2-3/10.
