MegaStar is an oustanding deep-sky charting program. It's the choice of many
MegaStar interfaces with most GoTo scopes, including the NexStar line.
Megastar's charting flexibility is one of its great features. In addition to
the standard naked eye charts, you can generate charts oriented to match the
views in inverting and mirror-reversing telescopes. The field sizes are
scalable. You can print charts with overlays representing eyepiece and finder
scope fields of view. They're almost infinitely customizeable.
But the centerpiece of this program is the database of 200,000 deep-sky objects
in more than 150 catalogs. You can activate one, all or any combination of
these for display. Addtionally, you can filter objects by magnitude and type.
For example, I'll never see a 17th magnitude galaxy in my 10-inch, so I set the
faint limit at 16.0.
One of my favorite features is the ability to orient the screen display with
the north-south axis rotated to any angle. This is great for comparing charts
against images or drawings. And speaking of images, MegaStar comes with more
than 78,000 thumbnails which can be set to automatically display when you seek
an object. If the database doesn't include a thumbnail for the object you seek,
you're a single mouse click away from downloading a DSS image which will be
properly scaled and aligned to match the display.
These features just touch the surface of everything MegaStar offers. If you're
seriously into deep-sky observing, this is the program you want.
