6th sketch in a row what is excellent according to the few sunshine we got. Most have be done in a very small hole in the cloud cover.
As promised, I changed the color around the sunspots.

I draw the sunspots first detuning the filter what give me a similar view as white light in very orange tint with much more detils around the sunspots including the penombra (I don't think is the correct name). Full tuned h-alpha, I don't see them.
