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
I 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!
