Radio observation in hydrogen line (1420MHz)

Plots of data collected using Brian Coleman’s self-made hydrogen-line feed placed at correct focal point on the LRO-H2 telescope (150cm Solar Cooker Radio Telescope) & pointed towards either outer Milky Way (1 spiral arm seen) or inner Milky Way (2 spiral arms seen) 16 May 2026

Lichfield Radio Observatory, UK.

Azimuth 168 degrees.

Elevation 75 degrees.

I have tested various distances of the feed from the centre of the dish over several weeks and concluded that this is the best result.

My 150cm LRO-H2 hydrogen line radio telescope is pointed azimuth 168 degrees, elevation 75 degrees, and collecting data by 24-hour transit scans. Which Milky Way parts does it pass through when trace shows one or two arms?
