Radio observation in hydrogen line (1420MHz)

Results of two day drift scan of Milky Way at 1420MHz (hydrogen line) using SDR, HNA and Phased Array.

On the plot below, the bright orange areas indicate when high signal has been detected, and green dots represent my signal detection. Aerial was aimed at Zenith. In the graphs showing my observations against galaxy (e.g. one immediately below), the round red and blue areas represent the major known radio sources – these are not my observations which are represented as green dots or variable coloured bar.
