Eyepiece Size Guiders and Planetary Cameras

Ultra Compact
High Senstiivty

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
1.2 Megapixel

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.


5 Megapixels

The QHY5P-II has 5.0 megapixels at 2.4um. Available in both color and monochrome versions. The sensor optical format is 1/2.5-inch. With its very high resolution, this camera is ideal for personal solar telescope imaging. Its 1.25-inch diameter allows it to be used in the eyepiece tube of a PST while solving the confocality issue common to them. The small pixel size provides high resolution images even without a Barlow lens.


Lowest Price

The QHY5R-II-C is our entry-level model, ideal for beginners. This camera is only USD99 but still offers the high-sensitivity, low-noise Aptina Color CMOS ASX340 sensor. The sensor is 1/4-inch with 720x576 resolution and a sensitivity of 16.5 V/lux-sec. Available in color only.


1.3 Megapixels

The QHY5II-M uses the On Semiconductor's MT9M001, 1/2-inch, 1.3 Megapixel monochrome sensor with 5.6um pixels providing 1280x1024 images. It can output 1280x1024@30fps and 320x240@320FPS. Available in monochrome only.

Items Included

Each QHY5II Series camera comes in its own metal box with USB cable, guide cable, focus ring and 1.25" extension tube.

High Sensitivity Low Price

Meeting or exceeding the specs of more expensive CCD cameras, these small high quality guider / imagers are an excellent value.

Great Travel Camera

QHY5II cameras are USB powered. No additional power supply or cable is needed. The small size makes them a great travel camera or backup camera as well as an excellent planetary camera.
