Overview
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, similar to the QHY5III462C. However, the QHY5III715C has four times as many pixels as the QHY5III462C, offering 4K resolution with 1.45μm pixels.
This makes the new QHY5III715C ideal for smaller, short focal length refractors. The exceptionally small pixels provide a field of view (FOV) of less than 1 arcsecond at focal lengths of 12 inches (300mm) or longer. The QHY5III715C inherits all of the updates and improvements of the QHY5III Series Ver. 2 line of cameras.
Extended Near-Infrared Sensitivity
The latest sensors feature deeper pixel wells, enhancing sensitivity to red and near-infrared (NIR) light. These sensors achieve peak NIR sensitivity nearly equal to visible light.
512MB DDR3 Buffer
The QHY5III (Ver. 2) cameras include a 512MB DDR3 buffer, doubling the memory of many deep-sky astrophotography cameras with 256MB. This reduces computer transmission load, ideal for high-speed planetary imaging.
New Front-End Design
The redesigned QHY5III (Ver. 2) cameras offer improved compatibility with a slim 8mm BFL, making them easy to integrate with off-axis guiders (OAGs). The 1.25-inch threaded adapter supports filters and interchangeable top glass allows seamless use of CS or C-mount lenses. A 1.25-inch filter wheel adapter connects monochrome cameras to QHYCFW3-S filter wheels.
USB 3.2 Gen 1 Type-C Interface
Upgraded to USB 3.2 Gen 1 Type-C, these cameras offer better durability and flexibility than the previous USB 3.0 Type-B. Use high-quality cables to avoid performance issues.
Universal Guiding Interface
The cameras now feature an ST-4 compatible guiding interface, replacing proprietary designs, allowing easy replacement of guiding cables at low cost.
Indicator LED
An indicator LED at the back signals camera status using different colors for diagnostics. It remains off during normal operation to prevent light contamination.

Let customers speak for us
from 174 reviewsBinoculars were easy to set up/focus for my eyesight (wearing glasses). Bundled instructions were easy to follow. Image is crisp and clean when focussing on distant objects(in daytime). Now just need some clear skies so can try them out at night.
A very convenient device for those times when you want to see the sun (or something very bright) and you want to still be able to see afterwards.
Easy to carry as it is small and flat.
Great scope, great accessories, but most importantly the best customer service I've ever seen from any business.
These arrived quickly and were exactly what we needed for seeing the partial solar eclipse! The flat cardboard rectangle ones are great if you wear glasses and find it hard to wear the goggle/glasses shaped ones, these flat ones you just hold up in front of your glasses and they are perfect :)
Arrived within 24 hours (amazing) as we ordered late. I appreciate that they are made to the ISO standard. Thanks!
Appears to be same model as the GSO brand on Aliexpress. Astronz price is same as if not better - shop local. Work fine on my short focus refractor.

Very fast service. This worked wonderfully to view the partial eclipse last Monday morning.
Solar viewers were fab! shame about the clouds for the recent partial solar eclipse but we will save them for the total solar eclipse in 2028!
We were a couple of days away from a partial eclipse when I realized I didn't have anything to safely view it with. AstroNZ had exactly what I was looking for, and at a great price. They must of shipped my order the second it landed because I received it the next morning! What a great team 😁
The heavy cloud over the lower North Island on the morning of the recent partial solar eclipse meant we didn't get to try out the viewers. But, hey they looked fine, and can go back in the cupboard until next time. The standards-stamp made me feel safe and comfortable about their safety.
