Observation of Moon, Milky Way and M17 with 5m dish antenna and CALLISTO
Galaxy moves to the 'left' with respect to the Moon. Or, in others words, Moon moves faster than the sky background. Right of the Milky Way we can see M17 or W38 with a few Jansky less than the Moon.

Observation of Cygnus A and the Milky Way with a 5m parabolic dish and CALLISTO
All channels between 980 MHz and 1260 MHz integrated. Channels with strong interference (sigma > 0.7 digits) are excludeded from integration. So from total 200 channels 169 could be used for integration in frequency domain.
