    Experience the Sony IMX178 CMOS Sensor

    • The Sony IMX178 back-illuminated CMOS image sensor offers high sensitivity, resolution and dynamic range.
    • The IMX185 is an "Exmor R" sensor with notably improved imaging features, including sensitivity and low read noise, by correcting the basic structure of "Exmor" adopted column-parallel A/D converter to back-illuminated type.
    • The IMX178 is a Sony STARVIS sensor and has a sensitivity of 2000mV+ per 1-micron square (when imaging with a 706 cd/m2 light source, f/5.6 in 1-second accumulation correspondent), and provides superior image quality in the visible and near IR light regions.
    • The 14-bit output helps achieve high dynamic range which lessened quantization noise and hidden dark random noise. This facilitates clear image quality in light and dark areas, even with high contrast imaging targets.
    • Everything required to control your ZWO Astronomy Camera is readily available at the ZWO website.

    Excellent Service and Excellent Product

    The ZWO ASI 178MC status More on the Way, but was delivered earlier than expected, fantastic! The unit met and exceeded expectation. Planetary has worked great and am currently working on DSO, expect good results.

    Great value for the money

    This is a good camera for the money. Although the description doesn't mention the lens it comes with, it's a 2.5 mm.

    nice camera

    Works well never used an astronomy camera before this. Takes some practice but overall works well. Instruction on how to use software is limited.

    ZWO ASI178MC

    So happy with my new camera and OPT service. USPS had lost my package for awhile and they were very helpful and accommodating. Will continue to do business with them. Great service and I really love the camera. Already getting awesome pictures of the sun with it in HA.
