|Suggested Sketching Materials:||
The highly detailed sketch above was contributed by Erika Rix of Ohio, USA. The full disc H-Alpha sketch was prepared scopeside using black Strathmore Artagain paper, white Conte’ crayon and pencil, Derwent charcoal pencil, and black oil pencil. One of the benefits of sketching white on black is that the entire image is displayed in positive format. Erika also notes that the black stock is much easier on the eyes when switching between eyepiece and sketch.
