Quick Overview

The monochrome CCD cameras with large dimensions sensors are no longer a dream! The QHY9 is the cooled camera equipped with a monochrome Kodak KAF8300 sensor with big dimensions (18.1 x 13.5mm) and high resolution (8 mega pixels - 3358 x 2536) that allows high performances at a price until now impossible!


Due to its high sensitivity, you can also use narrow band filters (to remove light pollution) while the powerful double Peltier cell cooling system gets the sensor up to -40°C than the outside temperature letting you record long exposures with incredibly low noise.

Details

The monochrome CCD cameras have the great advantage of having a much higher sensitivity than color cameras. So, in addition to allowing you to record weaker details, these cameras are perfect when used with the narrow-band filters (such as H-alpha, O-III or SII) that allow you to remove light pollution by greatly increasing the contrast of images. This makes it possible to photograph deep-sky objects (like nebulae) also from places with light pollution.

But mono CCD cameras are usually very expensive and this stops many amateur astronomers in the purchase. The QHY9 monochrome CCD camera changes the rules offering a Kodak KAF8300 monochrome sensor with large dimensions (18.1 x 13.5mm) and high resolution (  mega pixels - 3358 x 2536) at a great price. All of this combined to the double Peltier cell cooling system (which takes the sensor's temperature down to -45°C than the external ambient temperature incredibly reducing electronic noise in long exposures typical of astrophotography) and to an advanced 16 bits electronic A/D converter.



Technical comment by Filippo: "The QHY9 monochrome CCD camera is perfect for use with apochromatic refractors. In fact, the small pixels are perfect for these telescopes with short focal lengths (allowing you to record images with excellent spatial resolution) while the big size sensor helps to frame objects, even the largest ones in the sky".



 

 

Looking at the quantum efficiency graph you can see that the QHY9 uses a sensor with high sensitivity (QE up to 55% at 540m), but compared to other cameras with Sony sensors, it has larger dimensions.


 


Big dimensions and high resolution monochrome sensor

The QHY9 uses a Kodak KAF8300 monochrome sensor offering, at the same time, large dimensions (18.1 x 13.5mm) and high resolution (3358 x 2536) to let you record high resolution images. The compact pixel dimensions are perfect for low focal length telescopes (such as apochromatic refractors that usually have focal length lower than 1000mm) and it allows you to still have a high resolution.
 
The large size of the sensor allow you to frame more easily the object to record, even large faint objects. For example the QHY9 used together with AIRY APO104T refractor frames a field of 1,6° x 1.2°! You can for example record the entire nebulosity around the Pleiades, also having the high resolution required to define the finer details.







Double Peltier cell cooling system

In order to take pictures of deep sky objects (galaxies, nebulae or clusters) it's necessary to use very long shutter speeds (even longer than 10 minutes). In these cases the electronic noise management is critical. The double Peltier cell cooling system allows the sensor to cool down to -45°C compared to the ambient temperature drastically decreasing the electric noise.

This will let you record images even with very long exposure times. The QHY9 cooling system also allows you to precisely set the sensor working temperature: this way will be sure that the camera will record all pictures at the same temperature, regardless of the ambient one variation. This is critical to correctly calibrate the images being processed.






It includes control software

The QHY9 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.
