Description

Picture taken during COVID 19 closure in the darkest part of the Zagreb county, some 40km form Croatian capital.

Equipment - SW Equinox ED120 telescope on belt moded SW NEQ6 mount, using ATIK383L+ mono camera with filter wheel.

10X900s Luminance bin 1x1

3X180s R, G, B each bin 2X2

Apart from excelent details on captured galaxies, a significant number of Quasars is visible on photo. Notably most important is SDSS J124244.17+321741.5 with Z (redshift) 4.385 which means it recides from us with speed of 279805 km/s, light form that quasar originated before 12.326 billion LY, just 1.4 billion years after BB.
