NGC 1300 Eridanus 03h20m / -1925' 6.2' x 4.1' 11.4mag

The barred spiral galaxy NGC 1300 in the constellation of Eridanus on December 7 / 8, 2015. 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).

Twenty-two exposures of approximately 3 minutes at ISO 800 were stacked with no dark frame subtraction with Deep Sky Stacker (resulting in a 1 h 12 min exposure) and further processed in Photoshop. The galaxy doesn't rise high above horizon here in Switzerland and transparency was just average during the imaging session. In addition, light polution near the horizon had an impact on the visibility of the galaxy.
Equipment: Canon EOS 450D Baader modified camera, TeleVue Paracorr Type II coma corrector, 16" f/4.5 "Ninja" dobsonian telescope riding on a dual-axis Tom Osypowski equatorial platform, Lacerta MGEN autoguider, Lacerta off axis system (field of view comparison: image of the moon with the same equipment).
