Description

Identified: PK 355-4.1 or PN Hf 2-1 hiding in the outskirts of Ptolemy's Cluster (M7) in Scorpius.

This appears only arcseconds wide, smaller than many stars look in images.

To bring this out I restacked with a 3x drizzle and tone-mapped using starnet. If you zoom in you'll see individual pixels, its that small.

Unfortunately it was sitting right on the outskirts of my corrected field (spacing not quite right), so there's a bit of coma in the stars. But the nebula seems intact, almost looks like a pinwheel or clover.
