Star clusters are among the most spectacular objects for amateur astronomers to observe and image. They represent the beginning, the present and the future of the universe, from sparse open clusters containing only a dozen stars, to giant globular clusters, each replete with a million suns.Part one of this detailed book provides a comprehensive review of star clusters - including open, globular, extragalactic, and even cluster remnants - along with their evolution and physics.Part two is about observing. The larger clusters can be observed through the most basic equipment - normal binoculars or budget telescopes - but Mark Allison talks about instrumentation and accessories, for observers from beginner to expert. Finally there is an observing guide and a comprehensive observing list for a wide range of telescope apertures.This one book provides all you need to observe star clusters, and to understand the many and varied objects that fall under this classification.

A trip to the chocolate groves at Barnaby's Mill should have Fleur bringing in her seventh birthday with style, but when a band of hideous savages attack the party, seize Fleur and carry her away with them, an unimaginable nightmare unfolds. Can Fleur be her own saviour, and hatch an escape plan?

SQL-DMO is a feature rich library that developers can manipulate to get into those hard-to-reach corners that simply are inaccessible using Microsoft SQL Server's standard GUI tools such as Enterprise Manager. The SQL-DMO library allows DBAs and SQL Server application developers to manage replication and security scenarios, for example, with the kind of fine-tuning they just don't get with GUI tools. Allan Mitchell and Mark Allison explain how to do this in a straightforward, concise manner that simply explains the points necessary to help DBAs and SQL programmers advance to the next level of application development. Real-World SQL-DMO for SQL Server shows developers how to administer Microsoft SQL Server using the SQL-DMO object library. This book is packed with code and explanations on how to use the library to its full potential, and Allan Mitchell and Mark Allison offer advice about when--and even when not--to use the SQL-DMO application programming interface (API). With SQL-DMO, you can take a piece of Enterprise Manager and build an application around it. For example, in Chapter 2, the authors build an application to back up and restore a database. Also included is a freeware SQL utility, QALite. Real-World SQL-DMO for SQL Server will take developers and DBAs alike to another level in administering their SQL Server environments. The toolset that's provided with SQL Server becomes cumbersome when dealing with more than 10 servers and next to impossible when dealing with more than 30 servers. This book uses code tried and tested by the authors at sites where DBAs routinely manage more than 50 SQL Servers. Allan Mitchell and Mark Allison are longtime DBAs and cofounders of the successful UK-based consultancy Allison Mitchell (www.allisonmitchell.com). They are regular contributors at SQL Server user group meetings and were both recently honored as Microsoft SQL Server MVPs.
