Overview
The QHY600 uses the latest SONY IMX455 back-illuminated sensor, a full frame (35mm format) sensor with 3.76um pixels and native 16-bit A/D. This sensor is available in both monochrome and color versions. The sensor size is 36mm x 24mm. With the round body design, the QHY600 is an ideal camera to match the image circle of the new generation of RASA telescopes
Native 16-Bit
The new Sony sensor used in the QHY600 has native 16-bit A/D on-chip. The output is real 16-bits with 65536 levels. Compared to 12-bit and 14-bit A/D, a 16-bit A/D yields higher sample resolution and the system gain will be less than 1e-/ADU with no sample error noise and very low read noise.
Multiple Read Mode
- 51ke- in standard mode at 3.76um
- 80ke- in extended mode at 3.76um
One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. Even with unbinned, with 3.76um pixels, the QHY600 has a full well capacity of more than 51ke-. When binned 2x2 to 7.5um the full well is 196ke- and when binned 3x3 to 11um the full well is 441ke-.
Breakthrough Low Read Noise
- 1.0e- to 3.7e-
The QHY600 has only one electron of read noise at high gain and full resolution and 4FPS readout speed. One electron of read noise means the camera can achieve a SNR>3 at only 4 to 6 photons. This is perfect performance when conditions are photon limited, i.e., short exposures, narrow band imaging, etc., making this large area sensor ideal for sky surveys, time domain astronomy, fluorescence imaging, DNA sequencing and microscopy.
Back-Illuminated
Equipped with a Sony IMX455, the QHY600 is a back-illuminated Scientific CMOS Camera with extremely low dark current (0.003e/p/s@-20C) using SONY's Exmor BSI CMOS technology. QHY600 is also a zero amplifer glow camera.
2GB Image Buffer
In order to provide smooth uninterrupted data transfer of the entire 60MP sensor at high speed, the QHY600 has 2GB DDR3 image buffer.

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.
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.
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!
