What kind of equipment is needed?
You will need a high-quality system camera with an excellent telephoto lens, a fixed tripod and a motorised camera head. Further requirements: suitable weather conditions. A cloudless sky and clear views would be perfect. Unfortunately such conditions are the exception rather than the rule.
Once having taken the shot, approximately 1,000 - 5,000 photos must be stitched together into one, which requires a high-performance computer and, above all, an excellent stitching programme.
We currently use the following items of equipment:
Canon 5DsR, Canon M6 Mark II

Canon EF 2.8 300 mm L

The prefix "super" in "SuperGigaPixel" stands for optimised motifs. Image data shall be stored as efficiently as possible.

In this sense, particular emphasis is given to the actual, usable resolution in the picture rather than maximisation of the file size.
