Overview
QHY5III678M/C, the upgraded version of QHY5III 178M/C, is a new planetary and guiding camera of QHY5III V2 series with excellent near-infrared high sensitivity.
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 photons of longer wavelengths to penetrate further into the substrate. This dramatically increases the sensor's sensitivity to red and near-infrared (NIR) light. The sensor exhibits nearly equal peak sensitivity to NIR light as it does to visible light.
512MB DDR3
The QHY5III (Ver. 2) series planetary and guiding cameras are all equipped with a 512MB DDR3 image buffer which can effectively reduce the pressure on computer transmission, a great help for planetary photography which often requires writing a large amount of data in a short period of time. Some deep-sky astrophotography cameras on the market today only have 256MB, for example.
In comparison, the 512MB DDR3 memory of the new 5III (Ver. 2) series cameras represents a significant upgrade.
New Front-end Desn with Better Compatibility
QHY5III (Ver. 2) series cameras have adopted a new front-end design with improved compatibility.
The BFL (back focal length) of a V2 camera is only 8mm, which means you can easily integrate a V2 camera with your OAG (off-axis guider). The basic top adapter includes 1.25-inch threads, so you can still use your 1.25-inch filters.
The top adapter glass of the V2 can be easily swapped. One of the advantages of interchangeable top glasses is that you can use a filter even if you’re using a lens! You can add a 1.25-inch to CS adapter to connect a CS lens, or add a second CS-C adapter for a C-mount lens. Both adapters are standard accessories for V2 cameras.
Additionally, there’s a 1.25-inch filter wheel adapter available to connect your monochrome planetary camera to the QHYCFW3-S filter wheel.
USB 3.2 Gen1 Type C Interface
The new QHY5III (Ver. 2) series cameras all use the USB 3.2 Gen 1 Type-C interface. Compared to the USB 3.0 Type-B interface used in the previous generation, the Type-C interface offers a longer lifespan and greater flexibility.
Tip: It is recommended to use the official QHYCCD standard Type-C data cable. Since the market is flooded with a large number of poor-quality Type-C cables, using an inferior cable may cause the camera to malfunction. If you choose to use your own cable, please ensure it is of high quality.
Universal Guiding Interface
The custom interfaces used in the previous generation of planetary cameras and guiders have been replaced in the QHY5III (Ver. 2) cameras with a more universal ST-4 compatible guiding interface. Now, even if the guiding cable is lost or damaged, you can easily find a replacement on the market at a low cost.
Indicator LED
The new QHY5III (Ver. 2) series cameras are equipped with a status indicator at the back of the camera. If the camera experiences an abnormal condition, the coloured indicator light will help diagnose the issue, with different colours signifying different statuses. During normal operation, the indicator light is off, so there’s no need to worry about light contamination in the image.

Let customers speak for us
from 103 reviewsVery 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
I recently made a small purchase but gained a wealth of information and advice on my next scope purchase.
I can’t imagine shopping anywhere else for scope equipment. I was also delighted to acquire a PC connection cable for my now discontinued Meade Goto scope.
Very quick delivery of a great product, thank you
This eyepiece is a perfect addition for my older 8" Dobsonian telescope. Crystal clear view of 47 Tucanae and a nice view of M42 & even NGC2070. Ofcourse the planets are excellent. My older Dob' came with only 25mm & 9mm plossl so the 15mm is a welcome addition for casual observing.
Very nice. A lovely complement to my old pair 7x50 Tento (made in USSR). Recommend.
