you want a tiny camera for both planetary and autoguiding. The QHY5L-II is the best choice for you. After the success of QHY5 guiding camera(2006-2012), QHYCCD released the new generation Guide/Planetary Camera QHY5L-II.
QHY5L-II is using the APTINA MT9M034 CMOS sensor. QHY5L-II has both mono version and color version. Mono sensor has 74% high QE and it is very sensitivity for the light. It has very low readout noise also. At low gain it is apporx 7e and middle gain it is 4e. At high gain the readout noise is as low as 2e. With such high QE and low readout noise you just need a very small guide scope . 30mm diameter is enough and you can find the star everywhere.
QHY5L-II use 1.25inch style eyepiece shape design.It is very idea for the low weight guider setup. With the location ring it can get the confocal with the your eyepiece. It is very tight but still powerful. Improved thermal design can transfer the heat of CMOS sensor to the metal case quickly.
QHY5L-II has a high speed data transfer performance. It can get 30FPS@1280*960 and 200FPS@320*240. This frame rate is quite good for planetary capture.
The QHY5L-II supply WDM drivers. It means you can use it as a ultra high performance webcam for video chart or video livebroad cast. You can show the realtime astronomy scene to your friends with this camera.
The QHY5L-II's high sensitivity and low noise is another highlight in QHY5-II series. With unbelievable 74% QE QHY5L-II's sensitivity is even exceed many CCD camera's. It is said the QHY5L-II's image quality get or beyond the ICX618 based cameras.. The sensor's On-chip FPN(Fixed pattern Noise) calibration function solved the major problem of the CMOS technology. Image is clear and uniform even under high gain. With these advantage, QHY5L-II makes outstanding image quality for planetary imaging, guiding, deep sky imaging and all sky camera.
