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 119 reviewsGreat 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.

I bought a barlow lense and it's perfect for telescope viewing. Customer service was great too. Would highly recommend.

Excellent help and advice

Arrived quickly and was well packed. In perfect order. Easy to read, and easy to use. Makes finding stars homes very simple.

I bought the UHC Filter and picked up the order from Astronz office. I spent some time at the office and with Andrew. It was a delightful time to share our experience. I used the filter for several nights for observation. I took photos with my smartphone with the filter; the result is impressive, though not professional.

I screwed the T-Ring T2 to a 55mm M42 extension tube on my telescope. Then I attached my Canon EOS 800D to the bayonet end and noted a rather loose fit. I used the small allen key supplied with the adapter to loosen the three grub screws on the adapter. Firmed up the loosness fit and re-tightened the grub screws. Very satisfied with the quality.

Very good product and good service delivering it promptly.
