This is a pastel (white on black) made of Venus with my refractor 152/1200,
the used magnification was 120x.
To achieve this sketch I used white light (no filter) and a red filter #25A.
The Venus cusp's limits si far more than 180°
The observation was quite difficult very low and close to the sun with only 2.3% (disk illumination) but with a big 59" diameter.
