The DSES 9-foot dish is operational at Dr. Russel’s house in Colorado Springs. It is outfitted with a 1420 MHz feed with 2 low-noise amplifiers with over 40 dBi of gain and a noise figure of 0.35. The receiving system is a Spectracyber 1.
The output of the Spectracyber shows the relative peaks of hydrogen with a corresponding Doppler measurement.

Dr. Russel performed a drift scan of the visible sky and plotted the relative peak hydrogen signals.

The hydrogen maps very well to the visible Milky Way. The plot below converts the Celestial Coordinates into Galactic Coordinates. Note that the peak hydrogen is concentrated near the 0 Galactic Latitude.

Special Thanks to Ray Uberecken and Steve Plock for helping to set up the system.
