QHY model QHY5III715C color camera

The QHY5III715C is an ultra-high resolution back-illuminated color camera with extremely low read noise. The sensor has a 1/2.8-inch optical format, 4K resolution with 1.45um pixels. This makes the new QHY5III715C ideal for smaller short focal length refractors.

This camera enjoys all the upgrades and enhancements of the QHY5III series from manufacturer QHYCCD.

General Description

Ultra-high resolution back-illuminated color camera with extremely low read noise. Its 1/2.8-inch optical format sensor is similar to that of the QHY5III462C camera. However, in the new QHY5III715C it has 4 times more pixels than the QHY5III462C for 4K resolution with 1.45 um pixels.

This makes this new camera ideal for smaller short focal length refractors. The exceptionally small pixels subtend an FOV of less than 1 arc second at focal lengths of 12 inches (300 mm) or more.

Extended near-infrared sensitivity

In this latest generation of sensors, the photodiode portion of the pixel well is physically deeper than in previous sensors, allowing longer wavelength photons to penetrate deeper into the substrate.

This dramatically increases the sensor's sensitivity to red and near-infrared (NIR) light. The sensor exhibits nearly equal maximum sensitivity to NIR light as to light in the visible spectrum.

Introduction to the V2 Series of QHY5III cameras

512MB DDR3

The planetary and guidance cameras of the new QHY5III series (Ver. 2) are equipped with a 512MB DDR3 image buffer that can effectively reduce the transmission pressure of the computer. This is a great help for planetary photography, which often requires processing a large amount of data in a short period of time.

For example, today, some deep-sky astrophotography cameras on the market have only 256 MB. In comparison, the 512 MB DDR3 memory in the new 5III series cameras (Ver. 2) represents a significant improvement.

New front design with more compatibility

All cameras in the new QHY5III (Ver. 2) series share new features that make them more compatible.

The BFL of the V2 cameras is only 8mm, which means you can easily fit a V2 camera with your OAG. The basic top adapter includes 1.25-inch threads and you can still use your 1.25-inch filter.

The top adapter glass on these cameras can be easily changed. One of the advantages of interchangeable top glass is that you can use a filter even with lenses!

You can use a 1.25 inch CS adapter to attach CS lenses or add a CS to C adapter for C-mount lenses. Both adapters (1.25″ to CS and CS to C) are standard accessories for V2 cameras.

Also included is a 1.25″ filter wheel adapter for connecting mono cameras with the QHYCFw3-S filter wheel.

USB 3.2 Gen1 Type C Interface

All cameras in the new QHY5III (Ver.2) series include USB3.2 Gen1 Type-C. Compared to the USB3.0 Type-B interface used in the previous generation, Type-C has a longer life and is more flexible.

Tip: It is recommended to use the data cable supplied by the manufacturer. Many poor quality Type-C cables are currently on the market, the use of which may cause the camera to malfunction. If you use your own replacement cable, confirm in advance that it is a high quality cable.

Universal guide interface

The custom interfaces of the previous generation of planetary guides and cameras have been replaced in this new QHY5III (Ver.2) series with a more universal ST-4 compatible guide interface. This makes it easier to find spare parts at an economical price.

LED indicator

All cameras include an LED indicator on the back of the camera. This is a multicolor indicator that will help to determine problems in case of abnormal camera operation. During normal operation the LED remains off to avoid light pollution during the session.
