Shipping Calculator

The camera is well suited for solar imaging using short focal length telescopes that will capture a full solar disk within the FOV. 

Thanks to Sony's new global shutter CMOS imaging technology, this camera is able to provide clear and sharp images at high frame rates. The CMOS camera performance is comparable to CCD cameras, at the same time with lower readout noise and higher overall sensitivity and quantum efficiency than CCD sensors of similar size and cost. Pixelation is also eliminated.

This CMOS is a compact but powerful piece of equipment which features highly efficient heat transfer, reduced noise especially in high ambient temperatures.

Provides the shortest backfocus possible making the QHY5III174 an excellent choice for off-axis guiding.

LEMO style connectors for rugged durability.
