Description

This image is a result of a collaboration with Marcus Wögerer, who stacked and processed the collected data as follows:

6x2 min 800 ISO separate stacked in PS (median) to get sharp center.

16x4 min 800 ISO separate stacked in PS (average) to get maximum noise reduction.

Both results together stacked in PS (average).

Final processing in LR.
