SkyTools 3 is the Essential Software for Observing Comets PANSTARRS and ISON

Despite the hype in the media, even bright comets can be elusive targets. Don't be left standing out in the early morning cold wondering why you can't see the comet everyone is talking about! Magazines and web sites can only give a general idea of where and when to look. Successful observers know that you need software to tell you whether the best view is before dawn or after sunset and what you can expect to see from your location, in your telescope or binoculars, given your light pollution and horizon. But most software will only plot the location relative to the horizon... SkyTools does much more than that. Only SkyTools can provide reliable answers to the most important questions: where and when to look and what you can expect to see, customized just for you.

Exclusive features:

• Current magnitudes derived from recent observations

• Current coma diameters derived from recent observations

• Visual difficulty estimates

• Custom observing synopses

• Unique daily optimum viewing time charts
