... A few pictures on the progress of the #1 spectrograph. Currently residing in the work area on a lab bench, the spectrograph is powered and connected to the network. ... Also, the spectrograph's black mounting plates are visible on top of the blue case. The spectrograph's computer controls are displayed with its power source and Xyplex computer connection active on top of the case. The blue CCD as it would attach to the spectrograph is demonstrated. ...

The Hubble law produces a homologous expansion, which does not alter the shapes of patterns in the Universe. Other law such as a constant velocity (v = G*D 0 ) or a quadratic law (v = I*D 2 ) lead to a distortion of patterns. The picture above shows the result of expanding a familiar object by a factor of two using the constant velocity D 0 on the left, the linear Hubble D 1 law in the middle, and the quadratic D 2 law on the right.
