One way of taking a high resolution zoom-in zoom-out of a deep-space image is to take the region concerned at 2 different focal lengths, or to take a single frame and then a mosaic of frames of the region. This image showing the Running Man and the whole of the central part of the Orion nebula uses a combination of both techniques. The Running Man alone is a Hyperstar image taken at 550mm focal length, and the central Orion nebula image is a Sky 90 4-frame mosaic taken at a focal length of 450mm. Enjoy 🙂
