Overview
The QHY5III462 camera uses the Sixth Generation Sony 2.1 megapixel IMX462 STARVIS CMOS sensor. The pixel size is 2.9um making it the same size and resolution as the sensor used in the QHY5III290 camera that has been so successfully used for planetary imaging by some of the best planetary imagers in the world. Like other cameras in the 5III series, the QHY5III462 is USB 3.0 powered and controlled. No additional power is required.
The IMX462 sensor is back-illuminated and incorporates new technology that gives it some significant advantage over other planetary cameras: First, the IMX462 sensor has sHCG (Super High Conversion Gain) for very low read noise at high gain. This is ideal for stacking hundreds or thousands of short planetary images. Second, it is exceptionally sensitive in the NIR.
In this latest generation of sensors, the photodiode portion of the pixel well is physically deeper than in previous Sony BSI sensors, allowing photons of longer wavelength to penetrate deeper into the substrate. This dramatically increases the sensor’s sensitivity to red and near infrared (NIR) light. The RGB filters over the pixels become transparent at NIR wavelengths, so the sensor displays almost equal peak sensitivity to NIR light as it does to light in the visible spectrum.
The peak QE in the NIR around 800nm is as high as the peak QE in the visible wavelengths. For planetary imagers using a methane filter that passes light around 880nm this is welcome news.

Extra Information
SUPERB NIR RESPONSE: The QHY5III462C uses Sony's latest generation IMX462 back-illuminated sensor with extended red and near infrared response. It has nearly double the red and NIR sensitivity as previous generation BSI sensors and even greater sensitivity compared to front illuminated sensors.
SUPER HIGH CONVERSION GAIN: Sony's new sHCG (Super High Conversion Gain) technology produces a higher voltage from fewer photons resulting in greater sensitivity even at very low levels of light.
HIGH FRAME RATE: The QHY5III462C will output 135 frames per second at full resolution, making it perfect for planetary imaging.
FILTERS FOR VISIBLE AND IR IMAGING: The QHY5III462C comes with two free 1.25-inch filters: the IR850 filter and the UV/IR filter.
Let customers speak for us
from 231 reviewsAs 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.
An amazing device, incredible
Astronz 08" Premium Dobsonian Telescope
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.
great gadget
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!
