The result is cleaner images, smoother gradients, and greater flexibility during post-processing. Is SkyEye Plus Full-Frame & APS-C Camera for Astrophotography Worth it? Designed to cover a wide range of astrophotography needs, the SkyEye Plus Series offers both Full-Frame and APS-C cameras, giving imagers the flexibility to choose the sensor format that best matches their telescope, imaging targets, and workflow. From wide-field deep-sky imaging to high-resolution capture of faint celestial structures, SkyEye Plus combines advanced sensors, deep cooling, low read noise, and high dynamic range for consistently clean, detailed results. SkyEye Plus is specially engineered for: Advanced Deep-sky Astrophotographers Designed for experienced imagers, deep-sky enthusiasts, and remote observatory users who demand high sensitivity, low noise, excellent dynamic range, and reliable performance for demanding imaging projects. Imagers with High-End Optics & Complete Systems Whether you're using a compact telescope with an APS-C image circle or a premium optical system designed for full-frame coverage, SkyEye Plus offers the sensor format to match your setup. Full-frame models maximize field of view and optical coverage, while APS-C models provide an excellent balance of resolution, sensitivity, and system compatibility. Why Choose the SkyEye45AC Plus 5 USB Ports for Simpler Imaging Setups The integrated 5-port USB hub (4*USB2.0, 1*USB3.0) allows direct connection of accessories such as filter wheels, guide cameras, and focusers, reducing cable clutter and simplifying setup. Enlarged Front Window for Improved Illumination The enlarged front window of the SkyEye Plus full-frame camera improves illumination across the sensor and enhances compatibility with fast optical systems and larger imaging circles. 512MB DDR3 High-Speed Buffer Featuring an onboard 512MB DDR3 buffer, the SkyEye Plus series camera ensures stable USB 3.0 data transfer, preventing frame loss and transmission-induced amp-glow. The camera supports digital pixel binning from 1x1 to 8x8 (via stacking or averaging) and hardware pixel binning from 1x1 to 3x3 (via averaging). On-sensor hardware binning provides significantly faster readout speeds and processing efficiency than software binning. High-Efficiency Amp-Glow Suppression SkyEye45AC Plus is equipped with advanced amp-glow suppression technology, delivering a cleaner background and enhanced signal integrity for long-exposure deep-sky imaging. This helps astrophotographers capture faint celestial details with greater confidence and efficiency. Note: A minimal level of residual glow may remain under certain conditions. However, it can be effectively removed through standard dark-frame calibration without affecting the final image quality. Anti-Condensation Heating The SkyEye Plus series optical window features an integrated smart heating system that actively measures ambient temperature and humidity. It automatically applies precise heat to prevent condensation, keeping your optical path crystal clear without introducing disruptive thermal air currents. Two-Stage TEC Cooling The camera utilizes a high-performance two-stage Thermoelectric Cooling (TEC) system. By achieving a cooling from -35°C to -42°C below ambient*, the SkyEye Plus series camera cools the sensor deeply and consistently, delivering exceptionally quiet background noise levels for long-exposure imaging. *Note: Cooling performance may vary by model. Please refer to the product manual for detailed specifications. SkyEye Plus Series Camera Specifications ATR vs. SkyEye Plus: Which Series Do You Need?
