Re: (meteorobs) Radiant elevation help please



There is a "Precision Planet and Star Locator"  sold through Sky and
Telescope. That will do a reasonably accurate job of giving you both the
azimuth and elevation of the radiant through out the night.  It is much more
complex than the usual planisphere consisting of five disks, three graduated
and two index marks.  One scale corrects for your displacement from the local
time meridian, the second scale is for time of night, followed by date right
ascension and then declination.  The position is indicate by a spot in the
star map and the azimuth and elevation is indicated by a grid on the disk that
overlays the star map.  Unless you are requiring really accurate position in
azimuth and elevation this should do the trick.  It is large, nine inches in
diameter durable plastic.  The 35o model should fill your need quite well.  It
comes with an ephemera's of the Sun and planets and does may other functions
that are useful to meteor observers such as the coordinates of the antihelion
point that agree very well with Robert Lunford's value.
