Go-To Telescopes Under Suburban Skies is the first book
specifically written for amateur astronomers who own, or who are
about to purchase, a computer-controlled go-to telescope. Computer
control and automatic location of objects in the night sky is now a
feature of even inexpensive astronomical telescopes (under $200),
no longer just of the more expensive models. The advantage of the
go-to capability is enormous the telescope can be aimed at any
object in the sky with great speed and accuracy and so is the
popularity of these instruments.
GO-TO Telescopes Under Suburban Skies provides literally
hundreds more targets beyond those offered by the built-in nightly
tours that feature on the telescope s computer handset (a feature
incorporated by most manufacturers). Although most go-to telescopes
have enormous databases of objects they can find usually running
into tens of thousands the tours (that s suggested objects to look
at) are always very limited. Once you ve seen the planets and
bright objects that the computer suggests, you re on your own
This new book answers the question, What shall I observe next?
in a way that is unique to go-to telescopes. Unlike all existing
books on deep sky observing, GO-TO Telescopes Under Suburban Skies
doesn't waste space on RA/Dec co-ordinates or Star Maps and Finder
Charts for suggested objects. It is designed expressly to be used
alongside a go-to telescope, using the NGC and SAO menus on the
computer handset to quickly slew the telescope to each new target.
This is unique, and makes the book much more information-rich than
other observing guides.
Targets are arranged by season to maximise the chances of a
given object being visible at the time of observing, and then are
divided into four categories: three deep sky categories of
increasing difficulty, and then one category of stars that covers
things like coloured stars, multiple stars, and loose
clusters/streams. The reader can quickly turn to the relevant
season, and then work through the list of objects.
All existing books about practical deep-sky observing are biased
towards non- go-to telescope owners and usually assume
large-aperture instruments and/or dark, rural or desert skies. This
book makes the more realistic assumption that the amateur
astronomer has a relatively small telescope and is observing from a
backyard in a suburban area.
Instead of devoting page after page to maps and co-ordinates,
GO-TO Telescopes Under Suburban Skies leaves the computer to locate
targets by using NGC and SAO catalog numbers, and so has the space
to suggest many more fascinating deep-sky targets and provide
detailed observing lists and information about what's being
viewed.
