Best medium format lenses to use with my Sony A99 camera.

Admin May 19, 2026 No Comments

Using medium-format lenses on a full-frame A-mount body like the Sony Alpha A99 is a niche but very enjoyable setup if you like manual focus, unusual rendering, and superb central…

On two coincident muon detectors, with scintillators 5 x 5 cm horizontally, and 6cm between detectors what reduction in detection would you expect from geometry alone compared to 1cm between detectors?

Admin May 18, 2026 No Comments

For two identical horizontal scintillators of size 5 x 5 cm, the coincidence rate drops as detector spacing increases because the allowed angular acceptance narrows. A useful estimate is: tan(theta_max)…

Has anyone measured effect of temperature on response of scintillators in Cosmic Watch muon detectors?

Admin May 18, 2026 No Comments

Yes — there have been a few measurements and discussions of temperature effects in CosmicWatch-style scintillator/SiPM muon detectors, though not many formal dedicated studies. The main effect is usually not…

What are types of cloud chamber?

Admin May 18, 2026 No Comments

There are several major types of cloud chamber and related particle-track detectors. They all work by making charged particles visible as trails. 1. Diffusion cloud chamber This is the most…

When a muon travels through our atmosphere, what is the chance that it will interact with something in the atmosphere?

Admin May 18, 2026 No Comments

A muon passing through the atmosphere is very likely to interact many times electromagnetically, but very unlikely to undergo a major nuclear interaction or be stopped outright. The key point…

Are muons charged?

Admin May 18, 2026 No Comments

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?

Admin May 17, 2026 No Comments

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?

Admin May 17, 2026 No Comments

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

Admin May 17, 2026 No Comments

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?

Admin May 17, 2026 No Comments

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,…
