Astrophotography Performance

Extremely low read noise(1.4e-2.2 e), 1.4e @27db, high sensitivity and 14bit ADC make it very suitable for astronomy and microscopy high resolution photography.

Camera Sensor

Back-illuminated  CMOS Image Sensor with 14bit ADC. ASI178MM has a 1/1.8″ and 6.4M pixels sensor (IMX178) with SONY STARVIS and Exmor R Technology.

Notice: depends on user’s feedback, this IMX178 sensor has line pattern noise when do Ha solar imaging,  please take flat frame for calibration(out of focus or add a barlow lens to take flat frames). We recommend our ASI1600/ASI174 mono camera for Ha solar imaging.

USB 3.0 Port & ST4 Port

USB 3.0 Port: Can provide 5Gb bandwidth to let ASI178 run at 30 fps (14bit, normal mode) or 60 fps (10bit, high speed mode)  at full resolution(6.4Mega).

ST4 Port: Can be used connect with auto guide port of mount, for guiding.
