SV305 Pro 2MP USB3.0 1.25" Astronomy Guiding Camera

Capture Precise Planetary and Guiding Data with Confidence

The SV305 Pro 1.25" Astronomy Guiding Camera is engineered for accurate autoguiding and high-speed planetary imaging. Built around the Sony IMX290 1/2.8" back-illuminated CMOS color sensor, it delivers 2MP resolution (1920 × 1080) with excellent sensitivity and low noise. With a 1.25" nosepiece, it fits standard telescope focusers and accessories, making integration into existing setups straightforward for both observatory and backyard use.

Equipped with a USB 3.0 interface, the camera supports frame rates up to 100 fps at full HD for smooth planetary, lunar and solar (with a proper solar filter) imaging. The integrated 128 MB DDR buffer ensures stable data transfer, preventing frame loss or corruption during capture. An IR-cut filter, electronic rolling shutter, and exposure times from 1 ms to 30 minutes provide the control needed for both short planetary captures and longer guiding exposures.

Why It's a Smart Choice

• Accurate Autoguiding - ST4 guiding port with PHD2 and ASCOM compatibility allows reliable tracking corrections for long-exposure deep-sky imaging.
• High-Speed Planetary Imaging - Up to 100 fps at 1920 × 1080 lets you use "lucky imaging" techniques to resolve fine details on planets, the Moon, and bright targets.
• Flexible, Efficient Workflow - Any-area ROI support, 8/12-bit output, and standard UVC protocol on Windows and Linux streamline setup and integration with common astrophotography software.

FAQ

Q: Which telescopes is this camera compatible with?
A: It supports telescopes with a standard 1.25" diagonal base or focuser, making it suitable for most refractors, reflectors, and catadioptric systems.

Q: Can it be used as both a guider and imaging camera?
A: Yes. It is designed for autoguiding via the ST4 port and also performs well as a planetary, lunar, and solar (with appropriate filter) imaging camera.

Q: What operating systems are supported?
A: The camera uses a standard UVC interface and supports Windows and Linux, working with popular applications such as PHD2 and other compatible capture software.

Q: Does it require an external power supply?
A: No. The camera is powered via the included USB 3.0 cable (5 V, approx. 230 mA), simplifying field and observatory setups.
