- Large format full frame 60 MP sensor
- Exceptionally high dynamic range
- High quantum efficiency
- No amp glow
The Apx60 is the latest addition to Atik’s growing portfolio of CMOS sensor cameras. Utilising the Sony IMX 455 sensor, the Apx60 is our most advanced CMOS camera to date. The 61.17 megapixel sensor is perfect for large format, wide field views with outstanding detail, breaking through the boundaries of what is traditionally expected from a CMOS camera.
This camera offers exceptional build quality with innovative features such as in situ levelling and a built in USB hub, while seamlessly integrating with Atik’s advanced software solutions to deliver a complete experience for the astrophotographer.

No Amp Glow
The use of the absolute latest generation of Sony IMX Sensors allows for the readout electronics on the sensor to be turned off / quietened meaning that the Apx60 camera does not suffer from amp glow. Although amp glow can be ‘calibrated’ or dark subtracted out, at long exposures there is still a residual noise affect and a detrimental effect on the achievable dynamic range of the cameras. Atik Cameras worked from the premise that starting from a cleaner sensor is always preferable.
High Quantum Efficiency
Using a back illuminated sensor means that in situations where there is a limited number of photons, the Apx60 converts as many as possible into readable signal in the sensor.
Low Dark Current
The exceptionally low dark current of 0.0005 e-/p/s means that the noise component due to thermal build up is exceptionally low (an order of magnitude lower than other similar scientific long exposure CMOS cameras) allowing exposures in the tens of minutes to hours with minimal dark current noise.
Low Read Noise
Due to the fact that each pixel is read independently, CMOS cameras cannot bin in hardware to get the same signal to noise improvements as a CCD. However, with a read noise many times lower than CCD (1.2 e- vs ~6 e-) additive binning can realistically be considered. There is an added advantage that this also increases the full well by adding the single pixel full well capacities.
