The star trails in this image
were made by combining
106 exposures of 25 seconds
each. They circle above the
Castle of Noudar, a medieval
castle in Barrancos, Portugal.
The smallest trail, that of
Polaris, is to the upper right.

- FERRERO 6
This faint planetary nebula in
Cassiopeia wasn’t identified
until French amateur
astronomer Laurent Ferrero
found it in 2013. Its thin,
bright outer rim indicates
it is strongly interacting with
the interstellar medium.

The Seahorse Nebula
(Barnard 150) is a cloud
of dust and cold gas in the
constellation Cepheus the
King. We see it only because
of the dense star field behind
it. B150 stretches across 1°
in apparent length and lies
some 1,200 light-years away.
