Quick Overview

QHY21M is the perfect monochrome CCD camera for those looking for an ultimate instrument characterized by high sensitivity, thanks to Sony ICX674 sensor. The QHY21M CCD camera has a resolution of 1932 x 1452 and a sensor size of 8.7 x 6.6mm that, thanks to a cooling system with double Peltier cell, can be cooled down to -45°C in respect of the outside temperature !

So you can capture your best images with very slow shutter speeds, being sure to minimize electronic noise!

The QHY21M monochrome CCD camera offers, at a great price, the latest generation Sony ICX674 CCD sensor combined with the double Peltier cell cooling system (which incredibly reduces electronic noise in long exposures typical of astrophotography), to an advanced electronic with 16 bits A/D converter and to a very compact and light body.


Sony ICX674 sensor, 2.8 mega pixels resolution

The main feature of QHY21M CCD camera is the ICX674 sensor with high quantum efficiency and 1932 x 1452 resolution, that allows the QHY21M camera to record fainter objects and finer details. This sensor has a diagonal of almost 11mm and allows you to use 31,8mm filters (instead of 50.8mm version) even with telescopes very fast aperture ratio, significantly saving on the cost of these accessories.

Double Peltier cell cooling system

Imaging deep sky objects (galaxies, nebulae or star clusters) you need to use very long shutter speeds (even above 10 minutes). In these cases, the electronic noise management is critical. The double Peltier cell cooling system allows the sensor to cool down up to -45°C relative to the ambient temperature drastically decreasing the noise.

This, combined with the low electronic noise typical of Sony sensors and the special thermal design of QHY21M, allows you to record low noise images even at very long shutter speeds. The cooling system of QHY21M also allows you to set exactly the sensor working temperature: in this way you will be sure that the camera will record all pictures at the same temperature, no matter how varied the outside temperature. This is critical to correctly calibrate the photographs being processed. One of the strengths of this camera is the low power consumption, up to only 2A/h at full cooling operation.


It comes with control software

The QHY21M comes with EZCAP control software for Windows. The software, developed specifically for the cooled QHYCCD cameras, allows you to control all the camera's acquisition parameters, precisely focus the image and record images (including sequences) according to the shutter speed you want to use. This is a light and simple to use software, perfect for both astrophotography beginners and experienced amateur astronomers. The camera also have ASCOM drivers that allow you to control it with softwares like MaximDL or AstroArt.
