Camera ASI294MM Pro Cooled Mono
ASI cameras stand for very good workmanship and have modern CMOS sensors installed. This camera uses the state-of-the-art "back-illuminated" Sony IMX492 sensor.
Sony specifies a sensor diagonal of 21.63 mm. However, due to sensor refinement by ZWO the true diagonal is 23.2 mm. The 4.63 µm pixels of the ZWO ASI294MM Pro make this camera an all-rounder with highest sensitivity for short exposure times.
Advantages and features of the ASI MC294MMPro mono camera:
♦ USB 3.0 for a fast download - can also be used with USB 2.0
♦ 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.
♦ Powerful Peltier cooling up to 35 °C below ambient
♦ Sensitive CMOS sensor with 23.2 mm diagonal - 11.7 megapixels
♦ Good resolution through 4.63 µm pixels
♦ Comes with AR protection window - full transmission also in IR. If infrared should be blocked, an IR-cut filter is necessary.
♦ Distance from T2 connection thread (female) to camera sensor: 17.5 mm
♦ Very high sensitivity - QE up to 90% - ideal astronomy camera for dim objects
♦ 14bit ADC
♦ HCG mode - if gain is higher than 120 (12 dB), read noise is reduced below 2e- - result: low-noise images despite extremely high sensitivity.
♦ Full well capacity 66387e - even bright stars do not burn out anymore, you get a better signal-to-noise ratio.
Application ranges of the camera:
♦ Deep sky images (nebulae and galaxies): Due to the high sensitivity, nebulae and galaxies are captured after only a few seconds. By cooling down the camera up to 35 °C below ambient, the already low noise can be further reduced. By increasing gain (like the ISO setting of DSLR cameras), you can reduce exposure times below 30 seconds. Effects from seeing or inaccuracies of the drive are eliminated.
♦ Lunar and planetary images: extremely short exposure times (due to high sensitivity) freeze the seeing. Through the high resolution of the sensor, many details can be reproduced even at shorter focal length. Video astronomy is also possible.
The camera is often used on correctors that do not have a filter thread. In addition, the filters should always be used as close as possible to the camera. Here we offer you a solution that can do much more.
♦ 2" filter holder directly in front of the camera
♦ 360° rotation for the right choice of the image section
♦ Quick release - you can remove the camera from the remote ear at any time, without screws and thus entangling the cables
The adaptation is very simple, the 21 mm T2 extension is replaced by:
♦ 1x TSROTT2-T2 and 2x T2AbstimmA1
One tuning ring comes to the camera side, one tuning ring comes to the telescope side of the rotator. Then screw on the M42-M48 adapter with 16.5 mm length and you are in the right distance with the camera.
