I watched these proms today too, they were lovely, not quite what yesterday's monster was, but still great for a minimum!
Was this with a chroma?
Very best,

The CaK prom is great to see Apollo
The dark specks are typical of dust in the optical path (in 'the spot' clip), and should likely lie close to the chip based on their small size. The half circle artifacts look strange...very uniform in size and appearance. Will be interested to know what caused them. If you capture with Firecapture or similar software these can be removed quite nicely with flat fields...the dust specs at least. No promises on the other ones.
