For many years the struggle goes on to get a decent image of this dwarf spheroidal galaxy. It didn't get easier this time.
Leo II or PGC 34176 doesn't contain any material to build new stars and therefore no HII-regions. It rather looks like a loose globular cluster.

Only the luminance frames were used because of mediocre guiding and not fitting flats. And the focussing was bad.
