Measure angles with Astro::Coords::Angle or the angle method of Astro::Coord::ECI.

Implement star catalogs with Astro-Catalog

Locate stars with Astro::Coord::ECI::Star or Astro::Coords/Astro::Telescope:

#!/usr/bin/perl use strict; use warnings; use Astro::Coords; use Astro::Telescope; use Math::Trig 'deg2rad'; use Time::Piece; # Observer latitude, longitude and altitude # in decimal degrees and meters: my ($lat, $lon, $alt) = (38.899, -77.038, 16.68); my $star = Astro::Coords->new( name => 'Betelgeuse', ra => '05h 55m 10.30536s', dec => '07 24 25.4304', type => 'j2000', ); my $scope = Astro::Telescope->new( Name =>"$lat $lon $alt", Lat => deg2rad($lat), Long => deg2rad($lon), Alt => $alt ); $star->telescope($scope); $star->datetime(Time::Piece->new); print $star->name, "\n", "RA : ", $star->ra, "\n", "DEC:", $star->dec, "\n\n", "NOW: ", scalar localtime, "\n", "OBS: ", $scope->name, "\n\n", "AZ: ", $star->az(format=>'deg'), "\n", # Azimuth "EL: ", $star->el(format=>'deg'), "\n"; # Elevation

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
