For amateur-level radio astronomy, the most accessible astrophysical maser lines are those in frequency ranges where equipment is practical, affordable, and atmospheric attenuation is manageable. Here are the best options,…
WR-137 waveguide covers roughly 5.8–8.2 GHz, which puts you squarely in C-band.That is an excellent range for amateur radio astronomy, because it includes one of the brightest and most accessible…
Amateur radio astronomers can indeed detect natural astrophysical masers, though the practical options are limited by sensitivity, equipment, and local regulations. Here’s a breakdown: 1. Hydrogen (H I) Masers 2. Hydroxyl…
Hi all, I recently uploaded a new video to my channel about my 1 metre dish: I am planning to make a short series of video’s about observing the Sun,…
V669 Cas is quite variable it seems… https://hsweb.hs.uni-hamburg.de/projects/nrt_monitoring/stockert.html eduard 19:32This is also a very good resource for OH maser spectra and variability: https://hsweb.hs.uni-hamburg.de/projects/nrt_monitoring/index.html Wolfgang Herrmann 19:33And this one https://hsweb.hs.uni-hamburg.de/projects/nrt_monitoring/stockert.html
My article on the mini maser telescope can be found in the July-August 2022 SARA journalTo summarize what you need:Tracking mount; solid satellite tv dish; Norsat 9000LD LNB; Leo Bodnar…
At 22 GHz, the most prominent masers are water (H₂O) masers, specifically: 🔹 Water (H₂O) Maser at 22.23508 GHz 🔍 Astrophysical Contexts Water masers at 22 GHz are found in…
To build a 22 GHz water maser receiver, you’ll be targeting the 22.23508 GHz emission line, which is in the K-band of the microwave spectrum. This is advanced but achievable…
Another project underway is water maser radio observing. This requires a 1m dish (arrived today, below) and an LNB for 22 GHz (ordered from USA) and a HEQ5 Pro mount…
