Milky-Way at different wavelengths

Hi All,
Thought this may be of interest, How bright the Milky way is and how strong the Rado Spectrum signals are looking towards the centre of our Galaxy, Sagittarius (Sag.A a radio source), The chart shows the very powerful emissions (syncrotron continuum at 650 Mhz. in this case) of 1248 Jy., I took this strip chart a few years back (before UHF TV became overpowering) of the Sky from 9 Hrs. to 20 Hrs. RA Dec. of -28 Deg, using a Ph.Sw. Interferometer & 2 x 20 foot stressed parabolic antennas (all homebrew) obtained signals down to 2 Jy. (like imaging a Mag.16 object) which was fantastic, cant do it now too much RFI, but the nice small arperture of Scopes and Cameras do a mighty job visually, Pix of Milky Way 1 x 10 Min. at ISO800 guided (taken last year).

cheers.....Jim
