Description

This was a very diffucult picture, both due to the weak brightness of the object and the difficulty of processing. In fact, despite its magnitude being 9.2, it is an extremely faint object with details that are difficult to highlight.
This is the dwarf galaxy IC 1613 in the constellation of Cetus, in an area of ​​sky that is really poor in stars where it is difficult to keep a good guide of the telescope.

IC 1613 (also known as Caldwell 51) is an irregular dwarf galaxy 2.38 milion lyght-years away, visible in the constellation Cetus near the star 26 Ceti. It was discovered in 1906 by Max Wolf, and it is approaching Earth at 234 km/s.
IC 1613 is a member of the Local Group and it has played an important role in the calibration of the Cepheid variable period-luminosity relation for estimating distances. Other than the Magellanic Clouds, it is one of the few Local Group dwarf irregular galaxy where RR Lyrae-type variables have been observed; this factor, along with an unusually low abundance of interstellar dust both within IC 1613 and along the line of sight enable especially accurate distance estimates.
