About the CDK700 Telescope System

Key Features of the CDK700 Observatory System

CDK700 Optical Tube Assembly

  • Aperture and Focal Length: Boasts a 28-inch aperture and a 4540 mm focal length at an f/6.5 focal ratio, offering expansive deep-sky imaging capabilities and superb depth and clarity.
  • Advanced Optical Design: Features a Corrected Dall-Kirkham optical design, free of off-axis coma and astigmatism, achieving a perfectly flat field across a large 70 mm image circle, enabling critically sharp images across the entire viewing area.
  • High-Quality Construction: Constructed with ultra-low expansion fused silica mirrors and a rigid carbon fiber truss design, ensuring minimal thermal expansion and rapid thermal equilibration to maintain precise optical alignment under fluctuating temperatures.
  • Superior Mirrors and Coatings: The new light weighted conical primary mirror securely mounted at the center of the mirror is designed to maintain stable optical performance through the full range of elevation. All mirrors are coated with high-performance coatings that maximize light throughput while minimizing stray light, enhancing imaging quality under a variety of conditions.
  • Integrated Dual Nasmyth Focus Ports: Supports heavy instrumentation with over 300 lbs capacity on each focus port, facilitated by a controllable tertiary mirror that allows quick switching between instruments or cameras.

Integrated Direct Drive Mount

  • Innovative Direct Drive System: Utilizes state-of-the-art direct drive motors on each axis, providing smooth, fast, and virtually silent movement without backlash or periodic error, ideal for precise tracking and fast repositioning.
  • High-Resolution Encoders: Features high-resolution on-axis 26-bit absolute encoders on both axes, ensuring precise positioning and smooth tracking across the sky, crucial for high-end astronomical research, astro imaging, or satellite tracking.
  • Dual Nasmyth Focus: Includes a dual Nasmyth focus capability, allowing easy switching between multiple instruments and cameras without rebalancing the telescope, enhancing flexibility for both imaging and research.
  • Fast Slew Speeds and Rapid Installation: Capable of impressive slew speeds up to 50 degrees per second, the CDK700 ensures swift target acquisition. Additionally, its design allows for fast, one-day installation, making it an ideal choice for observatories looking to minimize setup time.
  • Advanced Tertiary Mirror System: Includes a software-controllable rotating tertiary mirror, which simplifies the use of multiple instruments and switching between different observational setups without rebalancing or refocusing.

Application-Specific Advantages

Astrophotography

The CDK700 stands as a premier system for astrophotographers, featuring advanced tracking capabilities and exceptional image stability that facilitate the capture of spectacular celestial images with intricate detail and vibrant colors.

Astronomy Research

For researchers, the CDK700 offers a robust platform for sophisticated photometry, spectroscopy, and detailed sky surveys. Its precise data collection capabilities and stable performance provide a solid foundation for scientific discovery and exploration.

Visual Observations

For visual astronomy enthusiasts, the CDK700 delivers vibrant and detailed views of the cosmos. Its significant aperture, coupled with high-quality optical components, ensures exceptional viewing experiences of planetary, lunar, and deep-sky objects, enriching every observational session.

Space Situational Awareness (SSA) and Space Domain Awareness (SDA)

The CDK700 system, with its precise direct drive motors and high-resolution encoders, is capable of engaging in SSA and SDA applications, such as tracking satellites and space debris. However, while it offers notable capabilities in these areas, it is not the ideal system for dedicated SSA/SDA operations due to its primary design focus on astrophotography and astronomical research. For those seeking a system optimized for the rigorous demands of SSA/SDA, we recommend considering the T-600 Direct-Drive Gimbal.
