WITH BLACK BACKGROUND

The composite sinks the outer veil with a black point and lets the corona fall to true black through a Gaussian taper, instead of carrying grey grain to the frame edge. Radii are in lunar radii, measured from the ring.

Tiles are blended additively on black, so overlapping coronae add rather than clip each other.

SIZE{{ frameSizeLabel }}

1296 is the framing at exactly one source pixel per output pixel — the crop is 900 of 1080, so anything smaller throws detail away and anything larger interpolates.
