Art McKay's "Effulgent Image"

Naomi Jackson Groves said of Art McKay's Effulgent Image that it
has the mesmeric magnificence of some far-off sun a billion years of age
Was it Comte who was certain we would never observe the surface of a star other than our sun?

From the CPU heatsinks problem, here is an idea for ensuring that the fuzzy star is at its best when viewed through a Newtonian telescope: a fan.

Arthur Fortescue McKay's technique, quote:
 [...] in 1997, Dr. David Howard described the painter’s  technique  as relatively simple. First, a layer of white  latex  paint was placed on  masonite  board. Then, using a scraper, McKay would create a rough geometric  shape  with a  series  of concentric lines or circles. Three dimensional  texture  was kept to a minimum [...]as any ridges of paint would be sanded or tapped down to maintain the two dimensionality of the geometric designs. The latex would be allowed to dry overnight before proceeding to the most important stage of paint application. (In many paintings a layer of another  colour  of enamel paint would be applied to create  colour  variation),” Howard notes. “The next day McKay would pour a layer of Northstar Stovepipe Enamel paint over the latex and then would scrape the  surface  again, very hard, from the centre outwards to the edge of the circle, square or rectangle being represented. The scouring of the  surface  reveals both the  latex  and residual enamel paint creating a materially flat image with extraordinary visual depth. (Howard, 2006)
