The hydrogen map develops!

The arms of the Milky Way are beginning to emerge in my 1420Mhz radio telescope using ezRA software and 86 x 86cm ex-military array.

I would particularly direct readers to the plot labelled on Y-axis as “Possible Galactic Atomic Hydrogen” below – which is showing the development of strong signal of a galactic arm – in this plot, yellow circle is Sun and green circle is galactic centre.
