Radio observation in hydrogen line (1420MHz)

Galactic mapping exercise 1420MHz so far 31/10/2023

By Admin October 31, 2023

3 different altitudes so far, all at 163 degrees azimuth (I used compass to day to check my “180 degrees azimuth” and it is actually 163 degrees) from Midlands, UK (Lichfield).

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

Radio observation in hydrogen line (1420MHz)

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?
