Description

The Pleiades taken at 200m f/4. With 80x75s my longest exposure so far. And due to its brightness quite easier to process than the faint nebulas in my other pictures.

What I really like is the nice contrast of the yellow star (HD23712) on the left side.

In version "C" I stacked a crop (50%) using the drizzle (3x) option of DSS. Therefore the pixel-size in that image is like a scope with 600mm focal length on a star adventurer (without guiding).
