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.

At first glance it seems quite light and the implication is that it can't really be all that powerful. However, light is what we want and it emits lots of lovely laser light! It's perfect for pointing out features to anyone else and bonus is that you can use a laser to align a scope or binos on the feature of your choosing by shining it through the scope finder or eyepiece (binos).
Just a note it to avoid shining the laser at anything reflective, as it can blind you very quickly. That includes road cones with their reflective tape. I can see how pilots are affected, it wouldn't take much.
Very helpful and knowledgeable team who offered ideas and suggestions without being too pushy. Very helpful.
As a stargazing newbie, I'm so glad I visited the showroom for advice! Andrew was super helpful and I'm very happy with my 8" Dobsonian :)
My comments are based on using it with a 102mm ED refractor, FL 714 mm. My home is in a Bortle 5 location in Christchurch.
This shorty Barlow is an apochromatic design, it uses a brass compression ring and is light at approx.100gms. I've used it several times in mostly poor viewing conditions, and once in above average conditions. In that time I viewed double stars, emission nebulae, open and globular star clusters, and Jupiter. I thought it provided excellent views and on the one occasion when seeing conditions and the city lights were less in the early morning, I was able to achieve 203 x magnification looking at a globular while still getting a reasonable view. Even at 238 x the view was tolerable, albeit quite soft.
I also have a Celestron X-Cel-LX 2X Barlow, so was able to compare the two Barlows. I found them pretty much identical in terms of colour, sharpness and contrast, though someone with better eyesight may notice differences that I can't.
I highly recommend the Astronz 2.5X Barlow, as it can provide substantially higher magnification options if you have, say 3 or 4 eyepieces. Personally, I prefer my 2 X Barlow as its more useful in less than average viewing conditions, which for me is most of the time. However, in above average to excellent viewing conditions, or at a dark sky site, the extra magnification of the 2.5 X Barlow would be very useful. If you are just starting out and wanting to get a Barlow, the Astronz one costs $48 cf. $249 for the Celestron. The choice is pretty much a no-brainer from that perspective.
I'll continue to use both, as different EP combinations and magnification steps will suit different viewing conditions.
The collimator arrived within 24 hours and was exactly what I needed. If didn't take long to realise the collimator itself needed to be collimated which was an easy process and added to learning how to use it. It was easy to use to collimate the Dobsonian Telescope. Thanks Astronz for helping me get underway with my new hobby.
I am so happy with the 8" Dobsonian. The fine focuser and the 2" superview lens where features which other beginner packages didn't have. I went to visit Andrew's store, he didn't confuse me or up sell, and he gave lots of time chatting and showing me the scopes, he gave advice for where to find dark skies and to come along to the societies meeting which introduced me to lots of great people and astronomy. I set the scope up within hours, within a week I had three amazing observing sessions, in dark skies not far from Auckland, the scope is simple and quick to set up and use and I am very impressed by how it has delivered beyond my expectations for power, useability and fun! Highly recommend Astronz
I am delighted to write a report for this product. It is extremely well made and combines a manual as well as electric function for focusing. This is important to me because with my other electric focuser, I was unable to use the telescope visually without having to dismount it. Now I am able to use it visually.
The focusing function allows very precise control. Unlike my previous focuser, there is now no problem from Schmidt Cassegrain mirror slop. I can now search for focus by adjusting in and out of focus and then when focus is found, set the counter to zero. I am a planetary imager and can now be very precise in searching for focus - even during a video capture. When experimenting beyond your "zero" point one can always return to that point precisely.
I have no hesitation in recommending it.
Cheers,
Paul Mallinson
Superbly easy to use and wonderful clear view while abl to clip on phone camera to other side made great photos
From what I’ve tried so far they seem amazing got a few more days to use them in Wellington NZ before we flight back to London so hopefully all good 👍 cheers Frank
I recently purchased the Celestron EdgeHD 8" Optical Tube Assembly from Astronz and had a very positive experience. The sales service was excellent, knowledgeable and provided helpful advice about the telescope and accessories before purchase. Astronz is run by experienced astronomers, which makes a big difference when discussing equipment and setup.
good quality and quick shipping. Andrew was great help.
Awesome definition, great contrast and sharpness.
Easy and reliable way to buy.
Perfect and helpful customer service.
The eye piece and the collimator are awesome.
