I am just beginning to use a new camera that has cooling, a ZWO ASI174MC Cool, which is also a colour camera.
My first image had no colour. I found out that in Deep Sky Stacker (DSS) has a section to set your camera colour sequence of the Bayer Matrix. Apparently what DSS is set to, does not match yours.
Go into DSS, and click on "RAW/FITS Digital Development Process Settings". At the top of the page, you will see a box to check just ahead of "Monochrome 16 Bit FITS Files..." Check the box, and that will activate the next thing down "Camera".
You need to choose the Bayer Matrix colour sequence that your camera uses. I found that my camera sequence was similar to a Canon 60D. You may need to do some searching on the internet to find out what sequence your camera has. Once you determine the sequence, you images will be converted using those parameters, and you should get your colour photos.
I hope this helps. CaleyAnn
