It records 1280 x 960 (1.2 MP) with 3.75 µm pixels on a 1\/3″-class sensor (4.8 x 3.6 mm image area, 6 mm diagonal), with 4.0 e⁻ read noise, a 13 ke⁻ full well and 12-bit ADC. It connects by USB 2.0 Type-C, carries an ST4 guide port, draws under 0.5 W and weighs 60 g, according to SVBONY.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis is a good match if you need a light, inexpensive guide camera for a guide scope or off-axis guider, with direct ST4 corrections or ASCOM pulse guiding through PHD2.
