Eduard’s list stuff needed for maser observing
My article on the mini maser telescope can be found in the July-August 2022 SARA journal
To summarize what you need:
Tracking mount; solid satellite tv dish; Norsat 9000LD LNB; Leo Bodnar GPSDO (for frequency reference); horn antennas for the LNB and frequency reference (homemade), and of course an SDR.
