![]() USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can better manage your cables. USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI294 Pro to run at 16 fps (14bit, normal mode) or 19 fps (12bit, high speed mode) at full resolution(11.7Mega). Notice: For the possible amp glow that shows on your images, please refer to this tutorial: " What is Amp-glow and how do I manage it? " Please check the dark frame to make sure you fully know the performance. ![]() ![]() Dark frame sample Highest dynamic range settings, 300s, -10☌, bin1. The dark current of the ASI294 is a bit lower than the ASI1600 at same temperature, based on our test results. The IMX294 sensor is a BSI (backside illuminated type) sensor, which has very high QE (quantum efficiency, which we estimate is over 75% peak). Even when used in higher humidity environments, ASI294MC Pro will still work fine without dew problems. Our camera design has been extensively tested and is very stable. There are four screws that seal the sensor chamber. Reliable MechanicsĪSI294MC Pro has same mechanics as ASI1600 Pro. This camera can achieve higher SNR(signal to noise ratio) with just one single exposure. Even bright stars won't saturate under long exposure. Full well CapacityĦ3700e full well, which is 3 times than ASI1600's capacity. Read noise will drop under 2e-, while dynamic range will remain at 13 stops. HCG (high conversion gain) mode, which reduces read noise to even lower levels at higher gain without loss to dynamic range, is automatically enabled when the gain setting is 120 or higher. At 13 stops, the ASI294 has even more dynamic range than the ASI1600. This is an excellent characteristic for deep sky imaging, which is inherently high dynamic range. The ASI294 has a 14bit ADC unit, allowing it to achieve 13 stops of dynamic range. 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.ĭDR memory buffer is the main difference between ASI "Cool" and "Pro" cameras. The ASI294MC Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. This makes the IMX294CJK ideal for astronomic camera market applications that require low-illumination performance. ▶Exceptional low-illumination performanceĮxceptional low-illumination performance of SNR1s: 0.14 lx is realized by use of a large-size optical system and by expanding the area per pixel to 4.63 µm.
