Product Description Back-illuminated CMOS Image Sensor with 14bit ADC. ASI178MC has a 1/1.8″ and 6.4M pixels sensor IMX178 with SONY STARVIS and Exmor R Technology. Extremely low read noise(2.2 e~1.4e), 1.4e @27db, high sensitivity and 14bit ADC make it very suitable for astronomy and microscopy high resolution photograph. Come with a 2.5mm all sky lens which can provide a nearly 170° view of the sky.

However, the camara has 14bits resolution, which means full-scale is only 16383 ADUs. Can you resolve this contradiction? Do you have absolute quantum efficiency numbers in (e- per photon) – not just relative?

Does the ASI178MC have an internal frame memory? If not, how are horizontal stripes avoided that occur when rolling-shutter-sensors are not read-out at absolutely constant speed? Reason for the question: while capturing, my computer has also other tasks to perform, like controlling the mount; so the computer alone can’t guarantee exactly constant readout-speeds. Last but not least: you say that your USB3.0-cameras work also with a USB2.0 controller in the PC when used with a MacIntosh, i.e. They are backward-compatible. Is that also the case when the ASI178MC is used under WINDOWS XP? Also with ASCOM-driver?

Also if full resolution is used? I am aware that the frame-rate will be significantly reduced in this case, but I hope that there are no other effects. OK, which AR protect window is compatible with this camera? The “ZWO D21 AR protect window” for $16.00 or the “ZWO D25 AR protect window” for $18.00 or the “1.25 Low profile Clear filter ASI Camera Protect window” for $20.00? The ASI178MC is not listed in the descriptions of these items. Another question: With the AR window installed, would the IR Pass filter work with the camera or is the IR sensitivity too low compared to the Mono version (for which the IR pass filter is recommended)?

Is there a big difference in the IR sensitivity of the 178MC with AR window compared to the 178MM or 224MC? Hi Sam, i have to decide between the ASI178MC and the ASI224MC. The small pixels of the 178MC will fit good to my f/10 scopes. Driver Digicom Usb Wave 54 C. I also like the higher resolution for dooing all-sky and the low amp-glow and read-out-noise of the 178MC. How is the sensitivity compared between the 178MC and the 224MC? There are huge differences in the full-well-capacity (15k vs 19,2k) and the g-sensitivity (425mV vs 2350mV). Is the ASI178MC better as an allround-camera for sun, moon, planets, all-sky and some brighter deep-sky objects or should i go for the ASI224MC?

Integrated with the latest USB 3.0 technology, performance is increased by 10 fold offering maximum speeds of up to 5 Gbps. In addition, the sleek aluminum casing not only protects the drive from overheating but also provides sound dampening qualities to minimize vibrations. The Vantec NexStar® CX 3.5' SuperSpeed.
