AI Thread Summary
Building a homemade radio telescope is feasible, with resources available for enthusiasts, including a detailed overview article from Astronomy and a comprehensive 33-page PDF guide. The designs shared in the discussion highlight simple setups capable of observing celestial bodies like the Sun and the galactic plane. The Society of Amateur Radio Astronomers (SARA) offers a community for sharing knowledge and experiences in radio astronomy. Additional resources and examples of DIY projects can be found through various links shared in the conversation. Engaging in this hobby can lead to exciting discoveries and personal observations of the radio sky.

I'm pretty sure my buddy up near Ottawa has a setup. I visited it last year.

Ah yes...

"We show two slightly-different designs for a simple, small, effective, radio telescope capable of observing the Sun, and the galactic plane in both continuum and spectral modes, easily able to show the hydrogen line in various parts of the galactic plane."

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
