20 Megapixel, High Res, High QE, Back-Illuminated Cooled COLDMOS Camera
The QHY183C is a one-inch, 20 Megapixel back-illuminated colour CMOS camera with a peak QE of 74%. The pixel size is 2.4um, yielding high-resolution with modest size telescopes. The camera is capable of producing 15FPS@20 Megapixels. It has a two-stage TEC that cools the sensor to -40C to -45C below ambient. The ADC is 12-bit / 16-bit with 1e- read noise! The computer interface is USB 3.0 and exposure times can be set from 50us to 3600sec.
Sony's Image Sensor Exmor R is a back-illuminated CMOS image sensor with improved sensitivity and noise reduction - the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It retains the advantages of CMOS image high-speed operation while dramatically improving sensitivity.
The QHY183C has a 128MB DDR Memory Buffer. A QHY183M 16-bit image is about 40MB, so 128MB of memory can easily buffer a full frame for transfer to the computer using QHY183M software with native single-frame shooting function, instead of intercepting a frame from a continuous video transmission. This makes data transfer to the computer stable and reliable because there is no USB bandwidth or busy CPU problems.
The QHY183C utilizes the Anti-Dew features common to the QHY COLDMOS cameras. A heated optical window prevents exterior dew from forming, and the CMOS chamber has a desiccant plug socket to prevent moisture from forming on the sensor at cold temperatures.
The QHY183C incorporates QHY's Anti-Amp Glow technology to significantly reduce typical CMOS amplifier glow to a minimum, allowing excellent calibration by subtracting a dark frame.

Let customers speak for us
Binoculars were easy to set up/focus for my eyesight (wearing glasses). Bundled instructions were easy to follow. Image is crisp and clean when focussing on distant objects(in daytime). Now just need some clear skies so can try them out at night.
A very convenient device for those times when you want to see the sun (or something very bright) and you want to still be able to see afterwards.
Easy to carry as it is small and flat.
Great scope, great accessories, but most importantly the best customer service I've ever seen from any business.
These arrived quickly and were exactly what we needed for seeing the partial solar eclipse! The flat cardboard rectangle ones are great if you wear glasses and find it hard to wear the goggle/glasses shaped ones, these flat ones you just hold up in front of your glasses and they are perfect :)
Arrived within 24 hours (amazing) as we ordered late. I appreciate that they are made to the ISO standard. Thanks!
Appears to be same model as the GSO brand on Aliexpress. Astronz price is same as if not better - shop local. Work fine on my short focus refractor.
Very fast service. This worked wonderfully to view the partial eclipse last Monday morning.
Solar viewers were fab! shame about the clouds for the recent partial solar eclipse but we will save them for the total solar eclipse in 2028!
We were a couple of days away from a partial eclipse when I realized I didn't have anything to safely view it with. AstroNZ had exactly what I was looking for, and at a great price. They must of shipped my order the second it landed because I received it the next morning! What a great team 😁
The heavy cloud over the lower North Island on the morning of the recent partial solar eclipse meant we didn't get to try out the viewers. But, hey they looked fine, and can go back in the cupboard until next time. The standards-stamp made me feel safe and comfortable about their safety.
