During   your   Night   Sky   Tour   you   will   be   peering   across   our   galaxy—and   beyond—through   a   14-inch diameter   (0.36-meter)   f/4.6   Dobsonian   telescope.      Its   giant   primary   mirror   is   made   of   low-thermal- expansion   glass   which,   when   cooled   by   three   attached   fans   at   the   beginning   of   the   evening,   can quickly reach a stable temperature for producing crisp views of the heavens. This   telescope's   primary   mirror   is   large   enough   to   capture   light   some   2,567   times   fainter   than   the average    dark-adapted    human    eye,    enabling    observers    to    view    objects    as    near    as    the    moon (240,000   miles   away)   and   as   far   as   2.4   billion   light   years   (14   billion   trillion   miles).   Its   optics   can resolve   detail   as   fine   as   the   width   of   a   dime   seen   from   a   distance   of   nearly   seven   miles   (11.2   km), and   a   variety   of   eyepieces   make   it   capable   of   magnifying   more   than   500   times   under   optimal conditions. With    42,000+    objects    in    its    computer    database,    this    electronically-controlled    instrument    will robotically   find,   center   and   track   fascinating   objects   around   the   heavens,   allowing   you   to   stand   or sit comfortably at the eyepiece for extended views of your favorite celestial bodies. From    under    the    clear    dark    skies    of    California's    only    International    Dark    Sky    Community ,    this telescopic   time   machine   will   transport   you   to   back   many   millions   or   billions   of   years   to   glimpse objects as they were long before humans walked the Earth.
