If any astro camera can be called an ALL-DOER, this is it!

  • Deep Sky Imaging: Best for a planetary camera! (Large pixels with high sensitivity and largest field of view of any current ZWO planetary camera!)
  • Planetary Imaging: Excellent (for large telescopes with long focal length)
  • Planetary Imaging in Near Infrared: No Problem (but if it's a priority, go for the ASI462MC)
  • Solar Imaging: Can be done! (but don't forget about a front-end solar filter!)
  • Live Streaming or All-Sky Camera: Very good!
  • Guiding: largest field for multi-star guiding (software dependent)

New ZWO ASI485MC USB3.0 Colour CMOS Camera with Autoguider Port cannot beat the ASI462MC when it comes to INFRARED IMAGING, but it is still usable, if infrared photography is not the main objective...

Otherwise, the extremely high sensitivity and super low read out noise will offer great performance for planetary imaging, solar and lunar imaging when used with a large telescope, so we would recommend it for telescopes with a focal length of 2000mm and above. 

And if you wanted a camera that can capture deep sky, but its sensor is not exactly tiny-tiny... you've just found it. It can be considered as the big brother of the ASI462MC with added benefits of great deep sky imaging capabilities due to its

8MegaPixel SENSOR with appr. 13mm diagonal size!

ASI485MC shares the same pixel size of 2.9um with ASI462MC, but when it comes to resolution, ASI485MC is 4 times bigger than ASI462MC. The total number of pixels is 8.28 million. The sensor length and width are 11.13mm*6.26mm. The diagonal is 12.86mm.

Extremely high sensitivity
One benefit of the back-illuminated CMOS structure is the reduced readout noise and improved sensitivity. Sony particularly uses the STARVIS™ technology on the IMX485 sensor, bringing it excellent visibility at low illumination. You may get very high light efficiency when taking astrophotos, also realize high picture quality in the visible-light and near infrared light regions.

This, combined with the large FOV provided by the big sensor format, makes ASI485MC not only ideal for solar, lunar and planetary imaging, also can be used as the live streaming camera, or all-sky camera to observe or monitor weather condition.

HCG Mode
ASI485MC has a built-in HCG mode which can effectively reduce the readout noise at high gain and keep the same wide dynamic range as you would expect at low gain. When the gain is 80, the HCG mode will automatically turn on. The read out noise fall off a cliff while the dynamic range still can reach close to 11 stops. The minimum read noise is 0.7 e.

QE curve
We assume the QE peak value of ASI485MC is 85% at 530nm.

Which one to choose? ASI485MC or ASI482MC?

If your main objective is deep sky imaging combined with some planetary imaging, but you cannot afford a cooled camera that was specifically designed for deep sky, go for one of these depending on the size of your telescope...

For small, compact telescopes we would recommend the ASI485MC and for larger telescopes with longer focal length (lets say over 2m or so) the ASI482MC would be a better choice for both deep sky and planets.

USB 3.0 Port & ST4 Port
USB 3.0 Port: Like other ASI cameras, the ASI485MC is powered and controlled via USB 3.0. It provides 5Gb bandwidth to let the camera run at 39fps (10bit, high speed mode) or 27.2fps (12bit, normal mode) at full resolution(8.2Mega).
ST4 Port: Can be used to connect with auto guide port of mount for guiding.
