Gray instead of RGB

mikeinlehigh

When I import my light subs they are in "grey" instead of RGB. I use Astrophotography Tool to acquire the images. My camera is an ASI294MC Pro. A setting somewhere? The camera driver?
Would appreciate a suggestion. Thanks
Looking back over images taken last year, some are "gray" some are RGB. How do I control this?

Except for the Foveon sensors, there is no such thing as a true color CMOS camera.

The "color cameras" are made out of little R, G and B filters over each pixel of a monochrome sensor. The raw captured image therefore consists of just grayscale intensities.

To recover color information from the raw data, you have to "undo" this color filter array. Most post processing programs will do it for you. Just read up on "Bayer filter," or "Bayer color filter array" on the web. After that, check on how to turn on "debayering" in your post processor.

It was nothing complicated at all. I didn't have a box checked on DSS that indicated I was using a color camera. One tick in the box...fixed 😁.

Wanted to move on to stacking in Pixinsight and away from DSS. However, stacking lights and calibration subs results in a "Grey" final image not RGB. Anyone know how to correct this?

Thanks again Chen. I will look up this info. Hopefully it will give me the setting to change to get my RGB end result. I had this same problem with DSS but found a box to "tick" and it took care of it. Several claim stacking with Pixinsight is better. To be determined...
