SkyTools 3 Database Power Search Tool
this powerful tool to mine the extensive SkyTools Standard/Pro
Edition databases for
objects to observe.
Near Earth Asteroids
16th magnitude or brighter that are above the horizon in
search filters that can be applied to any search:
or not -- only show those objects you have not yet
logged, or only those you have
within a radius -- only show those objects close to a
given object or position
one or more constellations
basic visibility criteria on a specific night --
specific acceptable altitude and sky darkness conditions
visual detection criteria - for a specific night,
location, and telescope. E.g. difficult or better, or
search criteria for:
-- select by magnitude, color, distance, proper motion,
etc. Search for variable stars or double star pairs
that meet your criteria. Include only those that
appear in one or more catalogs.
Deep Sky Objects -- select nebulae and clusters by
magnitude, diameter, distance, sub-type, etc.
Deep Sky Objects -- select galaxies, galaxy groups and
quasars by magnitude, size, distance, redshift, subtype,
etc. Galaxies can be selected by orientation, Hubble
class, surface brightness, radial velocity and eliipticity.
Planets -- select minor planets / asteroids by
magnitude, distance, apparent motion across the sky, orbit
class, or orbital parameters. Pro edition only.
-- select comets by magnitude, distance, elongation from the
sun, absolute magnitude, date of perihelion passage, orbit
type, or orbital parameters. Pro edition only.
