Two lessons I have learnt about practical aspects of radio-astronomy
Admin
Two important lessons I have learnt over last week,.by making these errors:
Mounting the Ptarmigan Triffid Military Phased Array to allow altitude to be varied.
Photos below show my attempt today to mount the array so that I can aim at Zenith and vary altitude between horizon and Zenith. I have yet to try it…
Successful detection of galactic atomic hydrogen in Milky Way using Ptarmigan Triffid Military Phased Array 21-22/9/23 in Lichfield, UK
I successfully detected hydrogen for first time using SDR, hydrogen HNA, pre-amp, DC block, and SDR# (using version of SDR# software provided in SARA Scope in a Box software package).…
Ptarmigan Triffid Military Phased Array Sept 2023
I have been given this incredible aerial/antenna this month – it a military phased array tuned to roughly the correct wavelength for hydrogen (1420MHz) with (I am told) a resolution…
Best astronomy images
Some of my favourite images taken by myself in Lichfield, UK, since I started astrophotography in late 2019 – combination solar, planetary and deep sky images.

CCDSPEC on Skywatcher DS Pro 72mm 8/6/2019
I own a CCDSpec spectrometer – this excellent British device is no longer made – but composes a single gold-coloured CNC-machined device that includes guiding port. It has diffraction grating…
Calibrating spectra from CCDSpec using Compact Fluorescent Lightbulb Feb 2019
It is convenient and easy to point the telescope at a compact fluorescent fluorescent lightbulb to use it as a calibration spectrum. Andy Calibration spectrum using Compact Fluorescent Lightbulb: On…
Spectra taken with CCDSpec spectroscope on Sky Watcher Equinox Pro 120mm OTA 18/2/2019
Below are some spectra I took using the CCDSpec spectroscope on my Sky Watcher Equinox 120mm telescope. Andy Capella (spectrum as comes from spectroscope and then plotted using RSPEC): Comparison…
