Meade - StarNavigator 130mm Altazimuth

The  VIXEN OPTICS R130Sf Newtonian Reflector comes standard with a quality 6 x 30 finder scope with a 7° field of view, 2 eyepieces and dovetail tube plate that fits all the Vixen mounts. This is a telescope new astronomers can start and grow with on a basic, user-friendly Porta II Mount (included in this package) and later move up to one of Vixens' electronic mounts such as the Sphinx SXW. *Universe Today says "The Vixen R130Sf is absolutely the perfect size for someone who needs enough aperture to light up popular deep sky objects (>magnitude 12!), but doesn't want to lug around a 12" telescope".  This lightweight 5" Newtonian reflector is a favorite of many new astronomers because it features remarkable light gathering (345x the human eye) with sharp images for its amazing price and size. With a standard 20mm Plossl more than the entire moon fills the eyepiece.  View innumerable star clusters and dark clouds, not to mention nebulas and galaxies. Add a 32mm and the heavens open up with a remarkable 2.5 degree field of view!  All of the stars in the Pleiades can be viewed at the same time. The visual observer will enjoy wide views of deep sky objects. Actual groups of nebula or clusters can be viewed at the same time with this instrument. The R130Sf comes standard with a dovetail tube plate that provides a solid and secure fit on all the Vixen mounts.

Vixen Porta Mount II (included)

The Porta II is a solid Altazimuth mount with a 20lb payload capacity and features Slow Motion Flexible Handles to minimize vibrations and keep views sharp. This is very useful in searching and tracking celestial objects.   When moving the telescope around the sky with this mount any vibrations are quickly and effectively dampened. The whole system is very stable, even when the tripod is at its maximum extended height. The mount head is easily removed to allow for a switch to a heavier tripod.  In addition, this is a great mount for terrestrial viewing. With no locks or clutches, the Vixen gear drives make it a simple matter to precisely track a planet or a ship on the horizon by turning the elevation and/or azimuth control handles. The Porta II Mount features slow motion control of both axes with flex handles, an accessory tray, and a solid central bolt for easy tripod changes,
