The internal RA and DEC motor wiring provides a clean look and an easy and trouble free set up. The CGEM series has a new innovative Polar alignment procedure called All-Star (patent pending). All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CGEM, sure to please astroimagers, is the Permanent Periodic Error Correction (PEC) which will allow users to train out the worm gears periodic errors, while the mount retains the PEC recordings. For objects near the Meridian (imaginary line passing from North to South), the CGEM will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM mount has a robust database with over 40,000 objects, 400 user defined programmable objects and enhanced information on over 200 objects. Celestron’s CGEM mount is the perfect fit beween the Advanced Series and CGE Series. |

Orion Telescope and Toe-Saver Safety Lights $39.99 Ink-black darkness is exactly what we amateur astronomers are after for observing with a telescope and astrophotography sessions. It’s hard to imagine any amateur astronomer complaining about it being too dark in the field. The only exception would be immediately after a, shall we say, painful and abrupt meeting between a telescope tripod leg and your toes. After such a stubbing experience, you probably wished you had some way of knowing exactly where your astronomy equipment was, without disrupting your dark-adapted vision. Wish no longer. Orion Telescope and Toe-Saver Safety Lights can help you prevent accidental bumps in the dark by virtue of three lengths of flexible red electroluminescent wire which can be wrapped around each telescope tripod leg so you always know where to wander without endangering your toes or knocking your telescope out of alignment. Orion Telescope and Toe-Saver Safety Lights include a handy control box so you can adjust the red light brightness to easily see where your astronomy gear is without disrupting your dark-adapted vision. The control box also allows you to choose between constant illumination or flash settings. The flash setting is useful if you prefer the safety lights to blink periodically during use. |
