Description

An image badly taken, twice: ISO 12800 is far too high and ISO 100 is just too low, as the "native" ISO setting for that camera is 160.  I stacked both series together hoping for the best, but I suppose that is not how that works.  At least the combined stack is much less noisy.
Lens fully zoomed in (focal length 37.1 mm, f:4.9).
