Latest picture of Perseus Arm of Milky taken at LRO at 1420.405MHz (hydrogen) frequency.
My latest picture of the Milky Way at 1420.405MHz is presented below. Processing in ezRA suite. No further post-processing or data correction on this image. Advantage of radio astronomy like…
LRO Cantenna at 39.4 degrees elevation, 163 degrees azimuth
ezRA software suite 24 hours data 3-4/4/2024 Successful detection of galactic hydrogen suggesting this cantenna can be used to map Milky Way in hydrogen. Andy
Successful detection of hydrogen line using homemade cantenna at LRO 3-4/3/2024
The following graph from ezRA suite shows successful mapping of hydrogen line across radio sky using my homemade cantenna over last 12 hours, although the later plots show that there…
Collecting and Processing hydrogen line Milky Way (elevation 77.3 azimuth 163 @ LRO) data for Alex Pettit 2-3/3/2024
Elevation 77.3 degrees Azimuth 163 from Lichfield, UK (LRO) 2/3/2024-3/3/2024, Nooelec 1.4GHz mesh antenna, Nooelec SAWBird+ H1 LNA, RTL-SDR Blog V3 Software Defined Radio. Data downloadable from link below –…
First light Home-made cantenna at LRO 3/3/2024@14:00
Just plugged in my homemade cantenna and the trace below on ezRA software suite (Ted Cline, https://github.com/tedcline/ezRA) immediately shows evidence of the hydrogen line – amazing how well an old…
How to orientate mesh satellite/WiFi dishes for radio astronomy
So the orientation that I currently have my dishes in above is incorrect – I need to rotate the dishes on their tripods by 90 degrees so the long axis…
Testing my 2 x 1.4GHz Nooelec Mesh dishes
I have now successfully tested both of these dishes using ezRA suite software, RTL-SDR Blog V3 SDR and one x SAWBird hydrogen line filters/cascaded amplifier. Results of tests: Left dish:https://astronomy.me.uk/testing-left-nooelec-1-4ghz-mesh-60x100cm-dish…
Testing left Nooelec 1.4GHz mesh 60x100cm dish 28/2/2024
I have now tested this aerial with RTL-SDR Blog V3 SDR and SAWBird H+ LNA – the graph below demonstrates successful data collection. Andy
Instruction Manual for Geoptik Nadirus 2BW Digital Setting Circles that do not require encoders
I recently obtained these new encoders – brilliant idea for my Dobsonian telescope! Turn it into pushto GOTO. http://astronomy.me.uk/wp-content/uploads/2024/02/Geoptik-Nadirus-2BW-Instruction-Manual-Feb-2024-FULL-VERSION.pdf Andy
