The iE1300 is a Plug-N-Play device. Plug each end of the USB cable into the iE1300 and your computer. Your computer will detect the electronic eyepiece as new hardware and start to install the driver. Follow the instructions on your computer for any driver installation.

Image Capture Software Installation

In order to bring an object to your computer monitor, an image/video capture program is needed. Most PCs come with preinstalled programs, such as Window Movie Maker, Arcsoft Webcam Companion, or other webcam program. If your PC does not have one installed, you may download one from the following website: VirtualDub 32-bit or 84-bit from or Future Winjoe at

Use iE1300

The iE1300 can be used with almost any telescope that is compatible with 1.25" format eyepieces. The camera is inserted into a focusing tube in the same way as a standard eyepiece, with or without a diagonal if you use a star diagonal. If your telescope does not have enough inward focus travel, you will need to use an 1.25" Barlow lens (not included) to extend the telescope’s focal plane to the camera’s imaging plane.

Aim and focus your telescope to an observing target using a regular eyepiece. Always start with a large number eyepiece, such as a 25mm one. Remove the eyepiece and insert the iE1300 camera into the telescope focuser. Slowly adjust the focuser knob to bring the image to focus. Use the capture function of the program to capture the image or movie. Practice your system during the daytime first.
