Overview
The QHY5III485C is a high-performance 4K color camera equipped with Sony's IMX485, back-illuminated CMOS sensor, offering 8.4 megapixels at a resolution of 3864 x 2180 pixels. With its 16:9 aspect ratio, this camera is ideal for video output, making it perfect for astronomical video recording and live streaming. It also features a 128MB DDR built-in image buffer to manage high-resolution data and enhance performance. Additionally, the camera includes a 2.5mm fisheye lens, transforming it into an all-sky camera with a 180-degree field of view.
4K resolution
The QHY5III485C uses Sony's new IMX485, back-illuminated, 8.4 megapixel color CMOS sensor with an array of 3864 x 2180 pixels at 2.9um. With USB 3.0 interface, the full frame rate of 44 FPS at 8-bits or 18.5 FPS at 16-bits. Smaller regions of interest will yield even faster frame rates.
16:9 resolution - More convenient video output
The resolution of QHY5III485C is 16:9, which is equivalent to the mainstream video output ratio. With the native high resolution, 485C can play a special role in recording astronomical video and astronomical science live broadcast.
DDR built-in image buffer
QHY5III485C is specially equipped with 128MB DDR built-in image buffer. In non-video output mode, DDR built-in buffer can effectively relieve the transmission pressure brought by high-resolution large data volume and reduce information loss.
Multiple Functions
The QHY5III485C standard package includes a 2.5mm Fisheye lens that converts the planetary camera into a high-resolution, 8.4 Megapixel All Sky camera with 180-degree field of view.

Let customers speak for us
from 231 reviewsAs a complete novice this is easy setup and go I already have some amazing nebula images
Had a problem with a mount and the Astronz team couldn't have been more helpful in supplying a part (a replacement PCB from their demo model) that I could fit and test. Just outstanding and responsive customer service.
Great design, no more lost thumbs crews!
Exactly what I wanted. Super fast delivery to Christchurch.
An amazing device, incredible
Astronz 08" Premium Dobsonian Telescope
I was pleasantly surprised when Astronz came up with a new RA axis lock to replace my broken one. Astronz always go the extra mile!
Nice product. Astronz were a great help advising me what I should get. Great sellers
As a stargazing company, we get most of our gear through Astronz. Customer relations with the team at Astronz are always pleasant and we find their products including this base to be A+. We recommend Astronz to all our stargazers.
Bought 8" Dobsonian from AstroNZ. It came securely packed, delivered promptly. Took a bit to assemble but was totally worth it. Have been able to view moon only so far, still not mastered to look at farther objects. But easy to use and great product. Will recommend to beginners definitely.
Weight arrived promptly and as described. Happy with the purchase
Great performance for its price point in an 8" SCT. Sharp across most of the FOV, with only slight softening at the edge.
great gadget
The telescope is great. I've got a lot to learn though it seems.
I haven't had as much viewing opportunities as I would like but you can't do much when you have 2 weeks of constant overcast. I like the crayford focuser, and the finderscope is high quality with a good aperture, the views of Jupiter, the moon, Carina and Orion nebula and Omega centauri have been great with the 30mm super view and 9mm, thinking about getting a 6mm, Barlow lens and a neutral density filter to expand my arsenal, so far going from a 60mm refractor to a 8in Newtonian hasn't been too hard. Collimating for the first time was a challenge but i have it sorted out. Only few things to point out is I don't think I got a manual but the video was plenty helpful, perhaps you could sell dew shields for the finderscope and to protect the secondary mirror as well as telescope heaters for active protection, potentially some new videos starring Andrew about star hopping to find dim DSO's without a computerized mount. Overall very happy with my purchase, with the 8in dobsonian being known as a lifetime scope I know It will always have a place in my heart even if I do upgrade to bigger and better scopes. Thank you Andrew for your great customer support and service. I bid you clear skies from the deep south!
