1. 서론
The Celestron NexImage 5 Solar System Imager is designed for capturing detailed images of celestial objects such as the Moon, planets, and the Sun (with an appropriate solar filter). This camera features a 5 MP ON Semiconductor MT9P031 CMOS sensor, providing high-resolution color images with sensitivity and low noise. It connects to your Windows PC via USB 2.0 and includes software for live video capture and image stacking.

3.1 망원경 연결하기
- Remove the dust cap from the NexImage 5 camera.
- Attach the 1.25" nosepiece to the camera by screwing it into the C-threads.
- Insert the camera with the attached nosepiece into the 1.25" focuser or diagonal of your telescope. Secure it with the focuser's thumbscrew.
- Ensure the camera is firmly seated to prevent movement during imaging.

3.2 컴퓨터에 연결하기
- Connect the supplied USB 2.0 cable to the USB port on the NexImage 5 camera.
- Connect the other end of the USB cable to an available USB 2.0 port on your Windows PC.
- The camera draws power directly from the USB connection, so no external power supply is required.

4. Software Installation and Use
The NexImage 5 requires specific software for operation and image processing. It is recommended to download the latest versions directly from the Celestron support web최적의 성능을 위한 사이트입니다.
4.1 iCap Software (Live Video Capture)
- Download and install the latest iCap software and drivers for your NexImage 5 from the official Celestron support page.
- Launch iCap. The software allows you to view live video from the camera, adjust exposure, gain, white balance, and frame rate.
- Use iCap to record video files (typically AVI format) of your celestial target. These videos contain multiple frames that will be processed later.
4.2 RegiStax Software (Frame Stacking)
- Download and install the latest RegiStax software from its official source or the Celestron support page.
- Open your recorded video file in RegiStax.
- RegiStax will analyze the video, select the sharpest frames, align them, and stack them to create a single, high-quality image with reduced noise and improved detail.
- Further processing tools within RegiStax allow for wavelets and other adjustments to enhance the final image.

5. 카메라 작동
5.1 포커싱
Achieving precise focus is critical for sharp images. Use your telescope's focuser to bring the image into sharpest view on your computer screen. Small adjustments can make a significant difference.
5.2 Exposure and Gain Settings
Adjust these settings within the iCap software. For bright objects like the Moon and planets, start with short exposures and low gain to prevent overexposure. Experiment to find the optimal balance for your target and seeing conditions.
5.3 화이트 밸런스
The NexImage 5 captures color images. Adjust the white balance in iCap to achieve natural-looking colors for your celestial objects.
5.4 고급 기능
- 적외선 차단 필터: The built-in IR-cut filter blocks unwanted infrared light, ensuring accurate color reproduction.
- C-Threads: The camera features C-threads for direct attachment to compatible optical accessories, offering versatility beyond the 1.25" nosepiece.
- Pixel Binning (2x2 and 4x4): This feature combines pixels to increase sensitivity and frame rates, which can be useful for dimmer targets or when faster frame rates are desired for stacking.
- 진행형 스캔: The camera uses progressive scan technology for capturing full frames at once, avoiding interlacing artifacts.
- Region of Interest (ROI) Sub-framing: Allows you to select a smaller area of the sensor to read out, increasing frame rates for planetary imaging where the target is small.

6. 유지관리
Proper care ensures the longevity and performance of your NexImage 5 camera:
- 센서 청소: The camera's sensor is protected by a glass window. If dust accumulates, use a blower brush or a specialized optical cleaning kit. Do not touch the sensor window directly with your fingers or abrasive materials.
- 저장: When not in use, store the camera in a clean, dry environment with its dust caps in place to protect the sensor and connectors.
- 손질: Handle the camera carefully to avoid dropping it or subjecting it to impacts.
