NGC2633 (or the Giraffe Galaxy as many call it) has a number of designations, including UGC4574, PGC 24723 and Arp80.

It was discovered on 11th August 1882 by Wilhelm Tempel and was included in Halton Arp’s  “Atlas of Peculiar Galaxies”. NGC2633 is located in the constellation of Camelopardalis and is classed as a Spiral galaxy of the 12th magnitude. It is thought to be about 100 million light years away, which was backed up with the redshift distance measurement of 90-110 million light years and approximately 65 thousand light years across.

Beneath the Giraffe Galaxy is NGC2634 – an Elliptical galaxy at approximately 104 million light years and beneath that is NGC2634A at 95 million light years distance.

Shown clearly in this image are two lanes of Integrated Flux Nebula (IFN) that are made up of low density dust and particles. They are illuminated by the residual light of our galaxy.  IFN are huge swathes of soft nebulous filaments that extend to the high galactic latitudes of the Milky Way. While IFN was first photographed on an optical plate at the Palomar Observatory in 1965, the huge extent of it wasn’t known for some time, largely due to the difficulty in photographing it as it’s so dim.
