What's in the Box
- 5 MP Microscope Imager with 2.0 USB Cable
- Adjustable Aluminum Collar (for 23mm and 30mm eyepiece diameters)
- CD/DVD with Celestron HD Digital Software
- Instruction Manual (this document)
Setup Guide
1. Software Installation
Before connecting the imager, install the Celestron HD Digital Software from the included CD/DVD. If your computer lacks a CD/DVD drive or if you encounter installation issues, download the latest software version directly from the official Celestron website. Follow the on-screen prompts to complete the installation. Note that the software may require the imager's serial number for activation, which is typically found on the product packaging or the imager itself.
2. Attaching the Imager to Your Microscope
The imager is designed to replace a standard microscope eyepiece. It accommodates eyepiece tubes with diameters of 23mm or 30mm. Use the adjustable aluminum collar provided to ensure a secure fit.

- Remove the Eyepiece: Carefully remove one of the eyepieces from your traditional microscope.
- Select Adapter: Determine if your microscope's eyepiece tube requires the 30mm adapter. The imager itself fits 23mm tubes directly.
- Insert Imager: Gently insert the Celestron 5MP Digital USB Microscope Imager (with the appropriate adapter if needed) into the microscope's eyepiece tube. Ensure it is seated firmly.

Operating Instructions
1. Launching the Software
After successful installation and connection, launch the Celestron HD Digital Software. The software should automatically detect the imager and display a live view from your microscope.
2. Adjusting Focus and Magnification
Use your microscope's coarse and fine focus knobs to bring the specimen into sharp focus on your computer screen. Adjust the microscope's objective lenses to change magnification as desired. Note that the imager provides a fixed magnification factor (approximately 30x compared to a 10x eyepiece), so the field of view will be more zoomed in than through a traditional eyepiece.
3. Capturing Images and Video
The software interface includes controls for capturing still images and recording video. Refer to the software's help documentation for detailed instructions on using these features, including selecting resolution (up to 5MP for still images, 30fps for video).
4. Using Advanced Software Features
The Celestron HD Digital Software offers advanced features such as:
- Measurement Tools: Calibrate the software to take precise measurements of specimens.
- Annotation: Add notes and labels directly to your captured images.
- Comparison: Compare two live streams or captured images side-by-side.
Maintenance
To ensure the longevity and optimal performance of your Celestron 5MP Digital USB Microscope Imager, follow these maintenance guidelines:
- Cleaning: Use a soft, lint-free cloth to clean the exterior of the imager. For the lens, use a specialized lens cleaning solution and cloth to avoid scratches. Do not use abrasive cleaners or solvents.
- Storage: When not in use, store the imager in a dry, dust-free environment. It is recommended to use a protective cap for the lens to prevent dust accumulation and damage.
- Handling: Handle the imager with care. Avoid dropping it or subjecting it to strong impacts, as this can damage internal components.
Troubleshooting
If you encounter issues with your Celestron 5MP Digital USB Microscope Imager, refer to the following common problems and solutions:
- Imager Not Detected / Software Connection Issues:
- Ensure the USB cable is securely connected to both the imager and the computer.
- Try a different USB port on your computer.
- Verify that the Celestron HD Digital Software is correctly installed and up-to-date. Download the latest version from the Celestron website if necessary.
- Restart the software and/or your computer.
- Image is Too Zoomed In:
- The imager has a higher magnification factor than typical eyepieces. Adjust your microscope's objective lenses to a lower power to achieve a wider field of view.
- Within the software, ensure you are using the native resolution (e.g., 960P) if available, as higher resolutions might involve software upsampling or cropping, leading to a more zoomed-in appearance.
- Poor Image Quality / Underexposed Images:
- Ensure the microscope's illumination is adequate and properly adjusted.
- Check the software settings for brightness, contrast, and gamma. While these adjust the display, proper microscope illumination is crucial for the initial capture.
- Clean the imager's lens and the microscope's objective lenses.
- Software Crashes or Freezes:
- Ensure your computer meets the minimum system requirements for the software.
- Update your computer's operating system and graphics drivers.
- Reinstall the Celestron HD Digital Software.
