Thanks Tom and everyone
Ken I see a huge amount of detail in the halpha view of the sun . It is a really enormous challenge to capture even a fraction of it. Constant tuning and focusing of the telesope is the only way to see sharp detail.
The sunspots umbra and penumbra are best visible when nothing else is , so I usually draw them first then tune up to see the mottling , filaments and proms. Even with these objects fine tuning and focusing shows varying detail in tiny amounts up and down the band.
Solar sketching is in my opinion the most difficult form of astronomical drawing. It is also the most frustrating and enjoyable activity at the same time. Frustrating because it is so difficlult to capture detail in the way that I see it . And is enjoyable while making that journey :-)
