Convex mirror is invaluable tool for halo-observers. Faint halos come up
much
better and the most faintest halos are seen only with aid of convex
mirror.
I've been using car blind-spot mirror. It is handy in a crowded place; no
need
to raise the hand. It is also good when driving car and in aeroplane to
check
the halos higher in the sky. And they are cheap; I bought them for
$1.6/mirror
last january from Fairbanks, Alaska. The evenness of the mirros surfaces
vary
a lot depending on the brand - some are really good.
