It pairs the high 6.4-megapixel resolution of the IMX178 with a full-resolution monochrome readout, making it a detailed planetary, lunar and solar imager for those who capture through filters.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eProduct Overview\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe sensor provides a 3096×2078 array of fine 2.4µm pixels across a 9 mm diagonal. A 14-bit ADC delivers smooth tonal gradation, read noise sits between about 2.2 and 1.3 e⁻, and peak QE is near 80%. Because it is monochrome with no Bayer filter, it resolves finer detail and captures more light than a colour sensor of the same size. Over USB3.0 it reaches up to 60 FPS in Raw8 and 30 FPS in Raw16 at full resolution.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis is a good match if you image the Moon, planets and Sun at high resolution and are set up to shoot through filters — LRGB for planets, or narrowband for solar detail.

With no colour filter array, each pixel records the full light passed by whatever filter is in the train, which is why mono sensors resolve finer planetary detail than colour equivalents. Its 15k e⁻ full-well and 14-bit ADC handle bright lunar and solar surfaces smoothly. The sensor sits at a 12.5 mm back focal distance, and the 66 mm body threads accept 1.25\" and M42×0.75 (T-thread) adapters. Exposures run 32µs to 2000 s.

For colour planetary results you add R, G, B (and often IR-pass) filters, typically via a filter wheel. Planetary imaging usually adds a Barlow or telecentric to reach f\/15–f\/25. Capture is over USB3.0, and the ST4 port accepts a standard autoguide cable.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eGood to Know Before You Order\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMonochrome output:\u003c\/strong\u003e colour planetary results come from imaging through separate filters and combining them; the camera records greyscale.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for speed, not long exposures:\u003c\/strong\u003e this uncooled camera is optimized for bright solar-system targets rather than faint deep-sky imaging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSB3.0 for full frame rates:\u003c\/strong\u003e USB2.0 works but caps throughput.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs it difficult to set up?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. It threads onto a 1.25\" or M42 connection, installs its driver, and appears in your capture software.
