Application context

Why this design is used

Choose the SkyEye24AC when your telescope and target benefit from Full frame, 36 × 24 mm sensor coverage, 5.94 µm sampling, two-stage TEC, ΔT ≥35 °C and 380–690 nm response.

Deep-sky astrophotography

Two-stage TEC, ΔT ≥35 °C helps control thermal noise during long exposures of galaxies, nebulae and star clusters.

One-shot colour deep-sky imaging

The colour IMX410 sensor captures broadband targets without a separate LRGB filter sequence.

Wide-field surveys and mosaics

Full frame, 36 × 24 mm coverage supports broad sky fields and efficient mosaic acquisition.

Photometry and time-series imaging

14-bit acquisition, 87.3 dB dynamic range and regulated cooling support repeatable quantitative observations.

System integration

Integration and compatibility

Use these checks to connect SkyEye24AC to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Lens and microscope interface
Mount: M42 / M54 astronomy adapters
Use a lens image circle that covers the sensor and check flange distance before adding C/CS, F-mount or M42 adapters.
Sensor and sampling
Sensor: Sony IMX410 color CMOS · Sensor Type: Back-illuminated full-frame color CMOS
Match pixel pitch to the diffraction-limited spot the optics deliver. Sampling finer than the optics resolve multiplies data volume without adding information; sampling coarser discards resolution you have paid for.
Interface and data rate
Frame Rate: 16 fps · Interface: USB 3.0
Confirm the host can sustain the interface bandwidth continuously, not in burst. A camera that outruns the write path stalls acquisition rather than dropping quietly to a lower rate.
Cooling and noise floor
Dynamic Range: 87.3 dB · Read Noise: 4.48–0.3 e⁻
Judge these figures at the exposure time you will actually use. Cooling matters where dark current accumulates over seconds; read noise dominates short exposures where it never does.

Technical FAQ

Integration questions for SkyEye24AC

What lens mount is required for the SkyEye24AC?
