Page 6: Qe Graph & Read Noise
ASI294 Manual 4. QE Graph & Read Noise QE and Read noise are the most important parts to measure the performance of a camera. Higher QE and Lower read noise are needed to improve the SNR of an image. Relative QE Curve for ASI294MC Relative QE Curve for ASI294MM Read noise includes pixel diode noise, circuit noise and ADC quantization error noise, and the... - Page 7 ASI294 Manual lower the better. As you can see, the Readout Noise of the ASI294 camera is extremely low when compared with traditional CCD cameras. In addition, it is with Built-in HCG mode, which can effectively reduce read noise at high gain and keep the same wide dynamic range for this camera as at low gain. When the gain is 120, the HCG mode will be automatically turned on.

ASI294 Manual 5.3 DDR Buffer ASI294 Pro camera includes a 256MB(2Gb) DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port. 5.4 Cooling system The ASI294 Pro camera have a robust, regulated cooling system, which means that the camera sensor can be kept at the desired temperature throughout your imaging session. -

ASI294 Manual 5.7 Analog to Digital Converter (ADC) The ASI294 camera can records in 14bit ADC and 12bit ADC. You can image at a faster fps rate if you choose to use 12bit ADC (high speed mode). This camera also supports ROI (region of interest) shooting, and smaller ROI range support faster fps. - Page 14 ASI294 Manual 1. 1.25” T-Mount 2. 1.25”filter(optional) Cooled color camera connecting drawing:...

Page 17: Cleaning
ASI294 Manual 7. Cleaning The camera comes with an AR protect window, which can protect the sensor from dust and humidity. Should you need to clean the sensor, it’s better to do so during the daytime. To see the dust, you just need to setup your telescope and point it to a bright place. One barlow lens is required to see these dusts clear. -
