Details:
A very large solar prominence on the northeast quadrant of the Sun has been putting on quite a nice show for the last several days for solar observers with Halpha telescopes. I captured this image yesterday (10/19). We had relatively clear skies, but with some pesky high cirrus clouds that made imaging a real challenge.
I hesitated to post this image, but decided to do so anyway mainly because it shows the size of the prominence - it was really big!
Note: The fringing grainy red aura especially on the left of the solar disc is an artifact caused by the high cloud cover. I was unable to remove it in post processing.
