Short answer: no — not reliably, and usually not at all. When you’re using an EQ6 mount (like the Sky-Watcher EQ6-R Pro) through ASCOM Platform and Stellarium, the system does…
This is a possible but untested solution. Make sure you tighten clutches before turning off your motors so that your antenna does not drop and hit ground or mount. Also…
1. Basic physics Cosmic-ray muons at ground level: Approximate stopping power in lead: dE/dx ≈ 1.5 to 2 MeV g^-1 cm^2 Lead density: rho_Pb ≈ 11.34 g/cm^3 So energy loss…
In SDR# (SDR Sharp), dynamic averaging is a running average of successive FFT spectra. It smooths noise and stabilises the display, but it is not a fixed integration time. Instead,…
The following has come from ChatGPT. (An ASCII text version of this post is available for people who have difficulty reading this page at https://www.astronomy.me.uk/calulat8ng-attenuation-of-muons-in-lead-ascii-text-version) Assessing the results from LRO…

This experiment was suggested to me at the last SARA online meeting. Here are the results – I started with zero and build up to 5, and to confirm went…
An X-Band feed has been installed on the 20m Skynet dish at Greenbank Observatory May 2026. What can we observe with it? Dimitry UA3AVR sent 14 May 2026: X-band on…
At 1420 MHz (λ ≈ 21 cm, the Hydrogen line), painting a steel dish with Hammerite (or similar metal paint) makes essentially no meaningful difference to RF performance, as long…
At 1420 MHz (the hydrogen line at 21 cm wavelength Hydrogen line), a steel dish performs essentially as well as any other good conductor—provided the geometry and surface quality are…
