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
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!
Exactly what I wanted. Super fast delivery to Christchurch.
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!
