The under mouth is the 23.2mm, 30mm and 30.5mm or 31.7mm straight inserted, can be installed directly in the biological or stereo eyepiece camera. Computer Imaging Capture andamp Video Recording: Captures still imagings and live video on your computer. The user-friendly software for Wins offers rich features including Stitching, EDF (Extended Depth of Focus) and video recording. Live video and still imaging capture can be set in different resolutions simultaneously. Multiple Measurements: Support performs measurements for single, parallel or perpendicular lines and rectangular, elliptical and irregular areas conducts measurements in microns, millimeters, centimeters, inches, feet, and etc. under any magnification powers with desired tolerances. More Features: Support adding layers, watermarks, mosaics, tiles adjust color balance, exposure, saturation, contrast, orientation change resolution, histogram, granulation, diffusion transform imagings via edges detection, digital imaging warping adds notes, measurements, text, arrows, labels, and etc. using customizable text with different sizes and colors. Compact Size: The color of the machine body is black with light outlook design. It is designed especially for troubles bothering traditional telescope users. Only by connecting it to traditional telescope can you release your eyes fettered on telescope to alternate traditional telescope into electron telescope immediately.
