CGEM Series Computerized Telescopes

Overview

$300 Off CGEM series telescopes

The CGEM™ mount has a fresh, attractive, bold appearance and is capable of carrying Celestron’s higher-end SCT optical tubes (up to 11") securely and vibration free which is ideal for both imaging and visual observing. 

Ergonomic Design - CGEM was designed to be ergonomically friendly with large Altitude and Azimuth adjustment knobs for quick and easy polar alignment adjustment.  The internal RA and DEC motor wiring provides a clean look and an easy and trouble free set up.

Innovation - 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.

Performance - 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 between the Advanced Series and CGE Series.  Offering the portability of the Advanced Series and the precision of the CGE.

First pic of Jupiter from my backyard. Keep in mind there was a lot of Sahara Dust in the low to mid-level of the atmosphere. Hard to focus.

My first astrophoto! Sky wasn't great, focus wasn't great, wasn't able to get the guiding working, but it's there.

International Space Station over Northern California

International Space Station over Northern California

The ISS came from the north-west and passed 81 degrees above the horizon on this night. It was 364 km above me when I took this image (Actually a stack of 4 images.) through my new C-11.

Visible are a Progress spacecraft docked to the Swesda module, S and P radiators, Columbus and JEM modules.

I have to give thanks to Frank Brandl for his advice and encouragement. I could not have captured this image without his help.

This is my second astrophoto. Various espoxure lengths ranging from 15 seconds up to 90 seconds, and about an hour of quality stacked photo's.

Pretty excited, it's my first decent shot.
