Easter Parade
A Photoshop rendering of the solar limb as seen with a 70mm refractor (a “Pronto”)
using a 40mm Coronado H-alpha filter and a 12mm Nagler (~40x).
The dynamic chromosphere of our Sun seldom fails to surprise me. A quick setup to
look at the Sun last Sunday (April 8th at local noon) turned into an hour-long
observing session when my telescope revealed a small eruptive prominence.
Unfortunately, the seeing wasn’t as good as it sometimes can be so I patiently
waited for steady moments. Over a hour’s time the “spire” prominence slowly changed
shape with structure — knots — brightening and disappearing. A small hedgerow
prominence (not seen in my drawing) remained virtually unchanged.
This is my first attempt at running one of my rough pencil sketches through
Photoshop. I hope, with time and practice — and better seeing — I can improve
my drawings.
