Beryllium varianten är dyr men ser intressant ut. AlMg alloy domen duger sannolikt. Mätningar kommer snart - HiFiCompass.

Intressant.
Ska bli kul att se distmätningar och se om beryllium är värd den extra kostnaden.
Tygversionen och aluminium ser ju dock intressanta ut också.

Udda med en papperskon också i en dome
