The barred spiral galaxy NGC 1300 in the constellation of Eridanus
on December 7 / 8, 2015 and on November 9 / 10, 2018. NGC 1300 is 61 million light-years from Earth and 110'000 light-years across. It is a member of the
Eridanus Cluster, a galaxy cluster containing 200 galaxies. NGC 1300 was discovered by John Herschel in 1835 (source: Wikipedia).
Forty-one exposures of approximately 3 minutes at ISO 800 were stacked with no dark frame subtraction with Deep Sky Stacker (resulting in a
2 h 9 min exposure) and further processed in Photoshop. The galaxy doesn't rise high above horizon here in Switzerland and half of the frames were taken from
a place with rather strong light pollution.
