I had good conditions for observing Venus. Mottled contrasted features were quite prominent. I am posting 3 sketches as I was testing out some new star diagonals with my 6" refractor. There are 2 versions that are dielectrically coated to pass selected wavelengths of light.
All sketches were done with a dirty blending stump along with some fingertip blending.
Below is with a stock diagonal.
