Overview
The IMX585 is a Sony Starvis II processor that enables high sensitivity and high dynamic range (HDR). It also improves sensitivity in the near-infrared range by approximately 1.7 times* compared to the IMX485. The new QHY5III585C camera has a large fullwell capacity of over 30ke-, approximately three times that of the previous generation QHY5III485C.
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 Design 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 multi-coloured indicator light will help diagnose the issue, with different colors 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 126 reviewsI've used this on my 8" ASTRONZ Cassegrain and it gives a fairly sharp image across most of the field of view. Being a long focal length telescope at 2436mm I wanted an eyepiece that gives me that little extra field of view when compared to my other 30mm eyepiece.

We were looking to buying a telescope for a while and finally made a decision to get one through Astronz. Contacted Andrew on a Wednesday and wanted to check whether we could get it deliver to Christchurch and luckily Andrew was driving down to CHCH for the weekend and by Friday we had the telescope personally delivered at no cost. It was great to meet Andrew as a person and his wealth of knowledge and genuine passion made the whole experience great. I would highly recommend Astronz

Many more discovery to see through it. Red colour on the moon was lovely to see with.

I had used a non-laser collimator earlier and compared to that this laser unit was far easier to use and took only a couple of minutes.

works way better than the celestron one I was using. I still have the same issue with the thread sticking but no way as bad as the celestron one.

Great addition to my telescope
Makes looking at the sky much easier
Good quality , Great value .

Worked as designed and can be used on other rigs as well

It was exactly what I needed and would have taken me ages to source. Thanks so much for a great service!
Happy with the sales integration with staff. Goods arrived on time and in good order. Looking forward to a bright future dealing with new Astronomy supplier

Exactly what was needed with fast delivery. Great trade!!!

Much better than my old x3 Barlow which was to powerful for my Tasco Galasee 144mm/500mm telescope. Clear and sharp.

Yeah, 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.
