H-alpha Sun – September 15, 2018

Scroll down to content

A very nice imaging session with the Sun today, using the newly acquired 150mm achromat refractor. The seeing was mostly good, and some very nice prominences were observable on the limb. Also a small active region was present.

Yesterday’s proms have now departed, but still a hint of their upper regions is seen in the image below:

And a two-frame evolution image:

One of the newly emerged proms, with a half-an-hour evolution:

And another prom, looking like a dancing flame:
