Planewave CDK300 Telescope System

Key Features of the CDK300 Observatory System

CDK12.5 Optical Tube Assembly

• Aperture and Focal Length: Features a 12.5-inch aperture and a 2541 mm focal length at an f/8 focal ratio, perfect for capturing deep-sky objects with exceptional depth of field and clarity.
• Advanced Optical Design: Utilizes a Corrected Dall-Kirkham optical design, eliminating off-axis coma and astigmatism while achieving a perfectly flat field across a 52 mm image circle, ensuring sharp and detailed images across the entire field.
• High-Quality Construction: The optical tube is constructed from lightweight and sturdy carbon fiber, reducing thermal expansion and allowing rapid cooling, which maintains optical alignment in varying temperatures.
• Superior Mirrors and Coatings: Equipped with rock-solid fused silica mirrors known for their low thermal expansion, along with high-quality coatings that maximize light transmission and minimize stray light.
• Thermal Management: Incorporates a sophisticated cooling system featuring three rear cooling fans and four boundary layer fans. This setup rapidly achieves thermal equilibrium, essential for maintaining consistent imaging quality during long exposure astrophotography and reducing thermal-induced focus shifts.

L-350 Direct Drive Mount

• Direct Drive Motors: Employs state-of-the-art direct-drive motors on each axis, providing smooth, fast, and ultra-quiet movement of the telescope with zero backlash and zero periodic error.
• High-Resolution Encoders: Integrated high-resolution encoders offer precise positioning, essential for capturing high-quality astrophotography and conducting detailed astronomical research.
• Azimuth Dovetail Balance System: Provides precise center of gravity adjustments, enhancing the stability and performance of the system in both alt-azimuth and equatorial configurations, crucial for maintaining accurate tracking and reducing strain on the mount during extended observations.
• Azimuth Dovetail Balance System: Provides precise center of gravity adjustments, enhancing the stability and performance of the system in both alt-azimuth and equatorial configurations, crucial for maintaining accurate tracking and reducing strain on the mount during extended observations.
• Rapid Target Acquisition: Equipped with direct-drive motors capable of slew speeds up to 50 degrees per second, enabling quick and efficient targeting of celestial objects and satellites, crucial for dynamic observations and time-sensitive astrophotography.

Application-Specific Advantages

Astrophotography

The CDK300 system is a powerhouse for astrophotographers, providing exceptional tracking accuracy and image stability which allow for capturing breathtaking celestial images with intricate details and vibrant colors.

Astronomy Research

Researchers will find the CDK300 invaluable for its consistent performance and precise data collection capabilities. Ideal for photometry, spectroscopy, and minor planet tracking, it serves as a reliable platform for scientific exploration and discovery.

Visual Observations

For those who enjoy visual astronomy, the CDK300 offers vibrant and detailed views of the cosmos. Its large aperture and high-quality optical components make it perfect for viewing planetary, lunar, and deep-sky objects, enriching every observational session.

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

With its swift and precise repositioning capabilities, the L-350 mount in the CDK300 system is capable of tracking satellites and space debris. However, it's important to note that while the L-series mounts are highly effective for astrophotography and research applications, they might not meet the optimal performance standards required for dedicated SSA/SDA operations. For those needs, we recommend exploring our T-600 Direct-Drive Gimbal, specifically engineered to exceed the demanding requirements for SSA/SDA applications, ensuring superior tracking and responsiveness in monitoring and cataloging space objects.
