Full Frame Astrograph for Deep Sky Photography SV555 | Svbony

Why choose this deep-sky photography kit?

Synergistic performance delivers a 1+1>2 photography experience：
The SV555's APO design + 2 ED glass elements accurately reproduce celestial colors while preventing chromatic aberration. Meanwhile, the SV241 Pro's automated dew control dynamically adjusts heating strip power in nights exceeding 80% humidity, preventing lens condensation from compromising image quality. Together, they form a closed-loop system from “capturing light” to “ensuring image integrity.”

SV555 Astrograph

1.The apo design employs a Petzval optical structure, incorporating two ED low-dispersion glass elements within a 3-group, 5-element objective lens. Combined with FMC full multi-coating, it effectively eliminates axial chromatic aberration. When capturing the Orion Nebula, the red Hα emission line and blue OIII emission line appear distinctly separated without edge color fringing.Even when photographing planets like Jupiter and Saturn, surface striations and ring details are rendered with precision.
2.44mm full-frame large image circle effortlessly covers wide-field deep-sky subjects, perfectly matching full-frame cameras. When capturing the Andromeda Galaxy (M31), stars remain sharp from the bright galactic core to the outer spiral arms, with no vignetting or distortion.
3.Detailed Design Features:
Precision Focusing: The helical focus ring features calibrated markings and rotates smoothly with zero backlash;
360° Rotatable Tube: Features a locking mechanism. When capturing subjects at different angles (e.g., vertical Milky Way shots or horizontal nebula images), simply rotate the tube to adjust the camera angle. Once locked, it remains stable during exposure;
Versatile Connectivity: The front M72 thread accommodates polarizing and narrowband filters, while the rear M48×0.75 thread is compatible with most camera adapters.


SV241 Pro Astro Power Controller

1.Multi-Device Power Management:
7 x 12V DC outputs (channels 1-5 independently switchable) + 3 USB 2.0 ports + 2 USB 3.0 ports + 1 Type-C port, simultaneously powering:
Equatorial mounts with stable power to prevent tracking interruptions;
Cooled cameras to maintain low temperatures and reduce thermal noise;
Simultaneously power electronic focusers, filter wheels, guide cameras, and other devices without multiple external adapters, instantly streamlining your photography setup.
2.Automated Dew Prevention:
Pairing with the SHT40 temperature/humidity sensor enables real-time monitoring of ambient humidity (5%-85% RH) and dew point temperature. When lens surface temperature approaches dew point, it automatically adjusts heating strip power via PWM (supporting 12V 6A output) to prevent condensation, ensuring consistent image quality throughout the shoot.
3.Remote Control with ASCOM Driver Support for Seamless Integration with NINA Astro Photography Software:
Monitor real-time power supply status (current, voltage) and temperature/humidity data from your indoor computer.
4.Multi-Layer Protection for Enhanced Device Safety:
Built-in reverse polarity, overcurrent, short-circuit, and 15KV electrostatic discharge protection.
LED indicators provide real-time status feedback.
