With 8.3 MP (3840 × 2160) and 2.0 µm pixelsit delivers high speeds and a high extremely low read noise for the Moon, planets, Sun (with appropriate filters) and theself-steering precise via ST-4.

Highlights

  • Sensor : Sony IMX678M monoSTARVIS 2, 1/1.8″ (7.7 × 4.3 mm).
  • Resolution : 3840 × 2160 (≈ 8.3 MP) - pixels 2.0 µm.
  • 12-bit ADC - Hardware ROI - binning numeric 1×1 → 8×8.
  • Playback noise type. ~0,4 → 0,6 e- (depending on gain), zero amp-glow.
  • Pleine-puits ≈ 11.6 ke- - QE peak > 83 %.
  • High speeds up to ~47-60 fps at full format (USB 3.0), > 100 fps at typical ROI.
  • Integrated ST-4 for self-steering - buffer (frame buffer) for stable transmission.
  • 1.25″ mounting (M28.5×0.6) + adapters C/CS - AR window.
