It uses Sony's back-illuminated 1\/1.2\" IMX585 (STARVIS 2) CMOS — an 8.3-megapixel array (3856×2180, 2.9 µm pixels, 12.85 mm diagonal) with peak QE near 91%. In a 40 mm body with a 1.25\" \/ M28.5×0.6 fit and an ST4 port, that large field makes finding and holding guide stars easy even in a short guide scope.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis is a good match if you want a guide camera with a large, sensitive field — so there is almost always a usable guide star in view — and the option to use the same camera for high-frame-rate monochrome planetary work.

Full-well capacity is 47k e−, read noise ranges 7.2 e− to 0.7 e−, digitised at 12-bit, with peak QE near 91%. Full-resolution readout reaches 47 fps in RAW8 over USB3.0 (5 Gbps, backward compatible with USB2.0). Sensor-to-flange backfocus is 7.5 mm — short enough to reach focus in most guide scopes and off-axis guiders — behind the D21×1.1 mm AR window. The 40 mm body uses a 1.25\" \/ M28.5×0.6 interface and runs from USB power alone.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutoguiding:\u003c\/strong\u003e a large-field, sensitive guide camera that keeps a guide star in view in short guide scopes and OAGs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlanetary imaging:\u003c\/strong\u003e high-frame-rate monochrome lucky imaging on a small scope with a Barlow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUtility imaging:\u003c\/strong\u003e a compact camera for framing, polar alignment and check exposures.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThe camera presents a 1.25\" barrel with an M28.5×0.6 thread and needs only 7.5 mm of backfocus, reaching focus in typical mini guide scopes and off-axis guiders.
