Eyepiece Size Guiders and Planetary Cameras
The QHY5-II Series uncooled cameras fit in a standard 1.25-inch eyepiece holder and have an adjustable location ring for confocality with an eyepiece. They are ideal for use as low-weight autoguiders or planetary cameras where short exposures are typical. The QHY5-II series cameras come in very small but powerful packages! The improved thermal design allows the heat generated by the CMOS sensor to be transferred externally to the telescope’s eyepiece tube.
Most Popular Guider
The QHY5L-II is our most popular guide camera for good reason, it has high sensitivity, an exceptional 74% QE, and low noise. The QHY5L-II’s sensitivity is even better than many CCD cameras. The read noise is remarkably low (~ 4 electrons) and the on-chip FPN (Fixed Pattern Noise) calibration function solves one of the major problems of CMOS technology, resulting in images that are clear and uniform, even under high gain. With these advantages, the QHY5L-II provides outstanding image quality for planetary imaging, autoguiding, deep-sky and all-sky imaging. Available in color and monochrome versions. The sensor has 1280 x 960 pixels at 3.75um and the camera is capable of 30 FPS in high resolution mode, 106 FPS in VGA mode..
