Sony IMX178 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.
Extremely low read noise(2.2e -1.4e) , high sensitivity and 14bit ADC make it very suitable for astronomy and microscopy photograph
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.

Customer Reviews
Great little camera! Took it out to set the focus with a Williams 50mm uniguide scope mounted on a camera tripod and took a photo of the Orion Nebula, unguided, (20 stacked). Very happy with photo for first try!
I’m very new to dedicated astronomy cameras this being my first. Everything worked right out of the box. I previously downloaded the software needed to hook up and one nice thing was the download covers all ASI cameras. The included 150 degree lens greatly increases the usage of the camera, being able to use it without the telescope. Still working on achieving the correct back focus for my image train but like I said.. a newbie. To get the most out of this camera I need to connect it directly to the computer because the shared USB port I planned on has too much traffic. Very satisfied so far.
