Description

A medium field view of the Lagoon and associated objects.

Observing the brilliant star fields of the Milky Way is like gazing upon a sandy beach, glistening in the sunshine. Just here along the beach, someone has planted their footprint.

Calibration frames from master libraries. Drizzle integrated at 2x scale for post-processing then cropped and down-scaled to standard UHD format.
