APS-C is a big size among one short color CCD cameras. QHY8L/8PRO is a 6 mega pixel camera with APS-C size SONY CCD sensor.
SONY's CCD sensor is famous because its low thermal noise. Especially with QHYCCD's 2-stage TEC and thermal construction design QHY8L has the cooling capability of -40C below ambient. It brings very clean image to you even in 30 minutes or one hour exposure.
QHY8L/8PRO has very low readout noise typical 6e or 7e. In a dark site it can give you a simple and easy way to capture the deep sky object. No need complex and high cost RGB filters and colorwheel. The image processing work is a lot more easy than mono cameras.
QHY8L/8PRO diameter is 63mm only. It is very small and very suitable for Hyerstar imaging.
QHY8L/8PRO comes with the cable clip and make the connection solid. You do not worry about any contact problem of the USB cable or power cable.
60% at Green (Peak) , 50% at Blue and H.a
Ultra small size suitable for primary focus imaging and Hyperstar
Difference Between QHY8L and QHY8PRO
Note: This spec is changed from -35C to -40C from 2014.1 wiith the price adjustment
How to select QHY8L/8PRO
First the QHY8L has a low price than QHY8PRO.
The major different is the CCD sensor. QHY8L using a Two field readout sensor.After exposure the Red and half of green pixel is readout for first.Then readout the blue and another half of green pixel. QHYCCD use technology to keep the two field exposure period the same. For long exposure there is no difference for them. To capture the fast movement object or fast various scene. We recommand the progressive scan sensor of QHY8PRO
