QHY5III174M/C uses a 1/1.2-inch, 2.3 Megapixel, SONY Exmore IMX174 CMOS sensor with global shutter.  Available in both monochrome and color. The large sensor size is a great choice for solar imaging and the large pixel size and high QE makes it excellent for deep-sky imaging as well.  Typical of all models in the QHY5III Series, this camera produces a high frame rate with the USB 3.0 interface, 138 frames per second at full resolution, up to 490 FPS at selected ROI.

Description

The QHY5-III series cameras are USB3 super-speed cameras and guiders. They can be used in a standard 1.25-inch eyepiece holder.  All QHY5III series cameras come in a very small but powerful package!

Customer Reviews (4.4 / 5 · 5 reviews)

Leo H. ★★★★★

The 1/1.2-inch sensor picked up far more detail on my solar filter shots than my previous camera ever did. Being able to use the full sensor area for guiding and imaging in one session has simplified my setup a ton.

Emma P. ★★★★★

The global shutter on this sensor freezes the action perfectly for my high-speed solar captures, and the 1/1.2-inch size gives me a much wider field than my old camera. Noise levels are impressively low right out of the box, even with short exposures.

Amelia V. ★★★★☆

The global shutter on this IMX174 sensor completely eliminated the rolling shutter distortion I was getting with my old camera. The large 1/1.2-inch chip captures enough detail for my lunar shots, though the 2.3MP resolution means I'm not cropping in too tight.
