Hello artists

Just a few hours after the great sketch of Stratos Tsanaktsidis, I had the opportunity to draw this one. I use a common H alpha PST Coronado.

My technique is quite original, after a light circle portion made by a graphite pencil on white paper I use directly a pure watercolour “green emerald” to sketch the solar surface on a water base and then the protuberances on the dry part of the sky, taking into account that light green will become dark red and vice-versa. Then I just have to invert the colours after scanning. The white sky is becoming black while the green part is becoming “H alpha red”.

Right, I add the approximate dimension of the earth and the moon orbit.

Clear sky to you all

Michel Deconinck
