QHYCCD QHY 247C

The two-stage TEC system actively lowers the sensor temperature to 45°C below ambient, which is critical for minimizing thermal noise. By keeping the sensor cool, you get much cleaner, higher-contrast images during long exposures, even on warmer nights.

The QHY 247C provides true RAW output, meaning it is compatible with all standard astronomical image processing software like PixInsight, DeepSkyStacker, or Photoshop. You have full control over your data without any baked-in processing.

The buffer acts as a temporary storage area for your image data before it is sent to your computer. It prevents data loss and ensures a stable, reliable transfer, which is especially helpful if your computer experiences brief USB connection interruptions.

The sealed chamber prevents moisture and dust from reaching the sensor surface, which is a common issue in humid environments. Combined with the included desiccant, this design significantly reduces the risk of internal dew or fogging during your imaging sessions.

While it is a powerful tool for serious deep-sky imaging, its APS-C sensor and USB 3.0 connectivity make it relatively straightforward to integrate into an existing setup. If you are ready to move beyond entry-level planetary cameras, this is a capable step up that offers significant control over your data.

The QHY 247C is specifically engineered to reduce amp-glow, which is a common artifact in many CMOS sensors. While some minimal glow can appear in extreme, very long exposures, it is generally easily calibrated out during your post-processing workflow.
