(meteorobs) Binocular meteors

The better the limiting magnitude, the greater the number of telescopic
meteors are visible compared with the viual rates.  That's because of
the restricted apparent field of view means the telescopic observer sees
an higher proportion of apparently fainter meteors, which are more
susceptible to poor conditions.

There were predictions that the Leonid display would be rich in faint
meteors.  Sadly I had to deputise at a business meeting, and was unable
to observe on Nov. 19 when skies cleared near dawn after snow the
previous night.

Why don't you try plotting them on charts on a regular basis?  We
telescopic observers are thin on the ground, and AFAIK non-existent in
the southern hemisphere.

We do have some charts online and I'm going to scan some more. For small
binoculars, star atlases which go to +9, like Uranometria, can be used,
or even print something using a planetarium/starchart package, as the
IMO charts don't extend far to the south.
