2012 05 17 – Prominence sequence
May 17, 2012, 13:35 UT – 18:41 UT
This interesting prominence doubled in size and then finally broke free of the limb. The time sequence spanned over 5 hours.
Northeast prominence at 30-degree position angle. Internally double-stacked Coronado Maxscope 60mm H-alpha telescope 400mm focal length, LXD75, Baader Planetarium Hyperion 8-24mm Mark III set at 8mm, 50x magnification.
Sketched with white Conté crayon and pastel pencil, white Prang color pencil, and black Strathmore Artagain paper.

Stunningly magnificent sketches! Are they however somewhat enlarged? I’m currently
Observing with a Quark Chromo and a 90 mm WO At mag 89x but do not see proms so large?
I guess artists licence allows for an enlarged interpretation
What are the dimensions of the paper?
I suppose trying to accurately mimic the ep view would make sketchaes too small?
Any suggestions much appreciated.
