Milkyway Hydrogen line high resolution drift-scan over one month

Description

Due to major storm periods in the month February,  I had to secure my Radio telescope to Zenit position for reducing wind forces on the dish.

I continued uninterrupted measurements at this orientation over the whole month

As a result I could manually stack  all 28 by 24 hour images together, which results to the high resolution image above 

X axis is the 2 Mhz Bandwidth of the Hydrogen line receiver. (Lowest Frequ. to the left)
Center frequency at  1.42 Ghz .
Deviations from this frequency shows the doppler shift.

Y axis is time, from bottom to top, enabling a so called "waterfall image" of the received signal over the full bandwidth

The right red vertical curve is the cumulated power over the 2 MHz Bandwith
showing  the Hydrogen power bumps two times the day at different galactic coordinates.

Galactic coordinates upper transit : Gal.Lng./Br.: + 93°  / 0° at 11h09m loc. time
Galactic coordinates lower transit : Gal.Lng./ Br.: +151° / 0° at 17h56m loc. time

At  the upper Milkyway hydrogen image, at the tail, we can barely see two regions of
higher density.
These are more distant spiral arms, apart from the closer Milkyway Perseus arm.

A faint vertical line within the image is a static stray terrestrial radio signal of unknown
origin.
