For Macs at least version 5.7 of Starry Night Pro or Starry Night Pro Plus
is required; Windows versions of Starry Night Pro as old as version 3 are claimed to work.
That's probably enough to tip the balance, and it's precisely what Imaginova was thinking when it added all these features to its popular planetarium software and called the result Starry Night Pro Plus 5.
I tested Starry Night Pro Plus supplied on DVD as version 5 with a free upgrade to V5.7 available online.
Starry Night Pro Plus does what it says on the box.
After spending a couple of evenings inputting a few comets into Imaginova's Starry Night Pro Plus
and displaying the results, I found a better way.
Starry Night Pro Plus
5.0 utilizes all the features of version 5 while adding greater telescope-control options and the pioneering CCD color mosaic originally released with Desktop Universe.
At the top of the heap is Starry Night Pro Plus
4.5 ($199.95), which allows you to enter your binoculars, telescopes, and eyepieces into a database, save an observation log, retrieve current images of the Sun and Earth, and access 500 million stars via the Internet.
