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 245 reviewsI bought my Dwarf Mini Smart Telescope around two weeks ago and have used it just about every clear night since. It takes less than five minutes to set up and EQ align, so even if I decided to build a more powerful imaging rig in the future, I can see myself still reaching for this scope just for the ease of setup and use alone. So far, I've had success imaging various galaxies, emission nebula, and star clusters, as well as the moon and sun using the included solar filter. The DwarfLab app handles image stacking and makes basic image processing really easy, although you can transfer the files into more powerful processing software if you want. For a tiny scope weighing only 840g and costing less than $1000, this little telescope is capable of some remarkably impressive astrophotography. Andrew from Astronz was incredibly generous with his time and knowledge, some of the best customer service I've ever experienced from any store!
Very powerful for its size. I am quite fearful to use as a night sky pointer. As i live directly under the north south flight paths. I continually checked flight radar and unfortunately, this proved a distraction to my star gazing and polar alignment.
Good product delivered on time with great survive
Fast delivery. Very happy,
Professional Tripod
I buy from AstroNZ mainly because of the friendly expert advice I get when I visit. The products they provide are also quality
Green Laser Pointer (RESTRICTED ITEM)
Great advice, awesome equipment. Highly reccommended
Excellent service and a good quality product. Due to weather conditions ( cloud) i havent been able to put through its paces yet
My Skywatcher 104mm scope had the original single speed focuser so this upgrade has made a phenomenal difference. Not long after ordering, i happened upon a skywatcher 120 and it also had a single speed focuser, amazingly enough, the astronz focuser also fits the 120mm. This is an amazing upgrade, this new focuser is so smooth compared to the old one and also has a longer draw length. Thank you Astronz
5kg counterweight, well packaged and quickly delivered.
Good quality items. The item met my expectations
As 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!
