It combines a 1:1 square field — no rotation needed to frame a target — with a full-resolution monochrome readout, making it a detailed high-resolution imager for the Moon, planets and Sun when working through filters.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eProduct Overview\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe IMX533 provides a 3008×3008 array of 3.76µm pixels, an 11.31 mm square imaging area with a 16 mm diagonal. A deep 73k e⁻ full-well gives wide dynamic range, read noise falls to about 1 e⁻, the 14-bit ADC delivers smooth tonal gradation, and peak QE reaches roughly 91%. The back-illuminated STARVIS design produces very low amp glow and clean dark frames. Over USB3.0 it captures up to 43 FPS in Raw8 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, want the extra sensitivity and detail of a monochrome sensor, and are set up to shoot through filters.

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. The larger square sensor and deep full-well suit bright, high-cadence solar-system targets. 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. The published weight is 160 g.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-resolution LRGB planetary imaging through a filter wheel.\u003c\/li\u003e\n\u003cli\u003eMonochrome lunar imaging behind a Barlow or long-focal-length scope.\u003c\/li\u003e\n\u003cli\u003eSolar imaging with suitable solar filtration or a dedicated solar scope.\u003c\/li\u003e\n\u003cli\u003eAutoguiding through the ST4 port.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eCompatibility \u0026amp; Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe camera connects through 1.25\" nosepiece or M42×0.75 threads and fits any telescope with those interfaces. For colour planetary results you add R, G, B (and often IR-pass) filters, usually via a filter wheel. Note the larger D32×2 mm window and 16 mm diagonal — use Barlows and filters that clear the larger sensor without vignetting. 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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUncooled camera:\u003c\/strong\u003e optimized for bright solar-system targets rather than cooled long-exposure deep-sky imaging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarger sensor:\u003c\/strong\u003e the 16 mm diagonal benefits from Barlows and filters rated for a wider field to avoid vignetting.\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.
