  • About the CDK24 f/6.5 Optical Tube Assembly

    CDK24’s Key Features

    Large Aperture and Moderate Focal Ratio

    The CDK24 features a substantial 610 mm aperture and a moderate f/6.5 focal ratio. This setup enhances its capability to capture deep-sky objects with remarkable detail, providing excellent light-gathering efficiency and a broad field of view for research and imaging.

    Advanced Optical Design

    Equipped with a state-of-the-art Corrected Dall-Kirkham optical system, the CDK24 offers exceptional image clarity. Its design eliminates off-axis coma and astigmatism and delivers a perfectly flat field, ensuring images are sharp and detailed across the entire field of view with minimal post-processing adjustments.

    Robust Mechanical Structure

    Constructed with a carbon fiber optical tube, the CDK24 is lightweight and durable. Its thermal expansion coefficient ensures minimal focus shift as temperatures change, making it ideal for prolonged observing sessions under varying environmental conditions.

    High-Performance Mirrors and Coatings

    Utilizing fused silica mirrors, the CDK24 maintains precise optical alignment and surface accuracy, even with temperature fluctuations. Its high-quality coatings enhance light transmission and reduce stray light, optimizing performance for specialized observational tasks.

    Thermal Management

    The CDK24 is equipped with cooling fans and a Delta-T ready system to achieve thermal equilibrium swiftly. These features help to minimize air turbulence within the tube, thus reducing image distortion and maintaining consistent imaging quality.

    Integrated Dew Control

    The telescope incorporates advanced dew prevention technology with heater pads controlled by PlaneWave’s software. This ensures that optical surfaces remain clear of condensation during humid conditions, thus maintaining clear and consistent imaging performance.

    Application-Specific Benefits

    Astrophotography

    With its large image circle and exquisite field flatness, the CDK24 allows astrophotographers to capture expansive and breathtaking views of the cosmos with incredible detail and clarity.

    Astronomy Research

    The precise and stable imaging capabilities of the CDK24 make it an invaluable tool for academic institutions and observatories engaged in complex astronomical research, including deep-sky surveys and detailed photometric studies.

    Visual Observations

    The CDK24 excels in visual observation, offering bright and crisp views ideal for star parties and serious visual astronomy. The telescope's large aperture and superior optical quality provide stunning views of planetary, lunar, and deep-sky objects, making every viewing session a remarkable experience.

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

    The CDK24 also lend itself to applications in Space Situational Awareness and Space Domain Awareness. Its capability to provide detailed observations can be essential for tracking and monitoring satellites and other space debris, contributing valuable data for space traffic management and safety initiatives.
