Are muons charged?
Admin
Yes — muons are electrically charged particles. A muon is similar to an electron but much heavier (about 207 times the electron’s mass). There are two types: The elementary charge…
If EQ6 mount is being controlled from Stellarium via ASCOM driver, then if I point the telescope at an object, then turn off the mount, and later turn the mount back on, will ASCOM be able to re-establish pointing position of mount?
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…
IEXOS 100 mount – can you turn off tracking – ie use it to point but without powered tracking as tracking causing RFI?
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…
Calculating attenuation of muons in lead – ASCII text version
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…
How does the dynamic averaging in SDR Sharp software relate to length of total integration?
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,…
How to calculate a table showing attenuation of muons by lead thickness, and analysing the results I have obtained at LRO with difference quantities of lead between two CosmicWatch muon detectors in coincidence arrangement 17/5/2026
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…

LRO Experiment to test effect of placing various amounts of lead between two x UKRAA CosmicWatch Muon Detectors in coincidence mode 16-17 May 2026
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?

Does painting the dish with Hammerite (trade name) metal-protective paint affect performance?
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…
