Description

This image is a 7-frame mosaic, made from 220 images, obtained with a Canon EOS 6D Mark II DSLR
Camera and Sigma 105mm f/1.4 DG HSM Art Lens at f/1.4 and ISO 1600, 30 second exposures and many
exposure stacked at each mosaic position. No dark frame subtraction, no flat fields. Tracking with a
Fornax Lightrack II and no guiding. The mosaic was made in portrait orientation with 3 frames on the
top row and 4 frames on the bottom row.

Top row, left to right: 25 frames (12.5 minutes), 23 frames (11.5 minutes), 16 frames (8 minutes).

Bottom row, left to right: 22 frames (11 minutes), 30 frames (15 minutes), 61 frames (30.5 minutes),
22 frames (11 minutes). The 61-frame position was centered on the constellation Orion, and short
exposures were made for the bright M42 region: 7 frames at 8 seconds, 8 frames at 3 seconds and 6
frames at 1 second were stacked.

The total exposure was 100.9 minutes, 199 frames. The full resolution image plate scale is 11.2 arc-seconds per
pixel.
