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 111 reviewsYeah, not bad at all. Nice crisp and clear and far more ergonomic on my dobsonian than a straight through. Price is on point, well worth it.

I bought a barlow lense and it's perfect for telescope viewing. Customer service was great too. Would highly recommend.

Excellent help and advice

Arrived quickly and was well packed. In perfect order. Easy to read, and easy to use. Makes finding stars homes very simple.

I bought the UHC Filter and picked up the order from Astronz office. I spent some time at the office and with Andrew. It was a delightful time to share our experience. I used the filter for several nights for observation. I took photos with my smartphone with the filter; the result is impressive, though not professional.

I screwed the T-Ring T2 to a 55mm M42 extension tube on my telescope. Then I attached my Canon EOS 800D to the bayonet end and noted a rather loose fit. I used the small allen key supplied with the adapter to loosen the three grub screws on the adapter. Firmed up the loosness fit and re-tightened the grub screws. Very satisfied with the quality.

Very good product and good service delivering it promptly.

Very happy with binoculars, great service, and excellent advice

A well made, versatile and useful accessory for 1.25 inch eyepieces. When using small telescopes without a prism or diagonal, there is sometimes not enough focus travel, this extension tube adds to the focus.

This adaptor works well with an iPhone 16 max pro. It’s easy to fit the phone and get it into an eye piece.
It’s a good way to determine what is and isn’t possible with an iPhone camera.
Steady hands with a 12” Dob can capture the Orion cluster. Open star clusters are also great targets.

Very happy with our new binoculars and great service from Astronz

A great product that is easily charged via usb-c.

I purchased the 8” Astronz Dobsonian and it’s been amazing! First use I was in awe of Jupiter and moons, Saturn, Orion Nebula, Matariki, things I’d never seen apart from pictures. Andrew was super helpful. It’s really easy to setup and use, really good quality, so much to discover!

I have set it up on my sky tracker and tripod, ready to try but due to busy work and no clear sky in the last couple of week I had no opportunity tu use it. Can you ask for my feedback a bit later please. I gave 5 stars for excellent service and support by Astronz
