QHY 5-III-715C CMOS camera

QHY 5-III-715 Color

The QHY 5-III-715 Color is another 2nd generation lunar and planetary camera with integrated SBIG ST-4 guidance port.Advantages over earlier versions of this camera series include:

• Large 512 MB internal DDR3 image memory.

• Improved front design
• Compatibility with CS and C-mount lenses
• LED for camera status indication
• USB 3.2 type C interface

We describe these and other benefits in detailhere.

The QHY 5-III-715 Color is aultra-high resolution color cameraWith a very sensitive Sony back-illuminated sensor (BSI) combined with extremely low read noise.The new USB 3.2 interface enables frame rates of up to 42 frames per second at full resolution (lucky images for the sun and moon), and significantly more for ROI (planets).

Due to the extremely small pixel dimensions of only 1.45 µm x 1.45 µm, an image scale (image resolution) of about 1 arc second is already possible at focal lengths of about 300 mm, so that reliable guidance is already possible without problems at focal lengths of about 300 mm. 200 mm.

Then, the QHY 5-III-715 Color with its 3,840 x 2,192 pixel array, very low read noise and exposure times of up to 900 seconds (although one should not exaggerate here, because, despite the low read noise, the camera is not cooled) is also an interesting variant for beginners in DeepSky photography.So, a telephoto lens with a focal length of 200 mm results in an image of the sky field of approximately 1.6 x 0.9 degrees, with a focal length of 500 mm it is still 38.5 x 22 arcminutes (approximately the size of the full moon).

Extended sensor sensitivity in the near infrared spectral range (NIR)

Similar to theqHY 5-III-462C CMOS camera(#1931026,€ 295The new QHY 5 III 715 C also features extended sensitivity in the near-infrared spectral range.

In this latest generation of Sony sensors, the photodiodes are embedded deeper into the substrate than in previous sensors, allowing photons with longer wavelengths (NIR) to penetrate deeper into the substrate.This dramatically increases the sensitivity of the sensor to red and near-infrared light.The maximum sensitivity (quantum effectiveness) of the sensor in the NIR spectral range is almost as high as that of light in the visible spectrum (see figure below).

Spectral quantum efficiency of the QHY 5-III-715 Color sensor

This opens up new photographic possibilities for the viewer.For example, in planetary photography of Jupiter and Saturn, cloud structures in the methane band can be made visible with the use of an appropriate filter:Baader Methane-Filter 1¼" (889nm, 8nm)(#2458295,€ 239. For the DeepSky Photographer, the sensor makes it possible to "see" deeper into the dark galactic clouds.
