I guess those of us who use Canons should just throw them all in the trash then.
Lol, way to take it the extreme! Nobody said you can't get amazing shots with a Canon, but there's no disputing the measured and analysed sensor metrics showing Sony sensors are superior. For the vast majority of astrophotographers the final image quality determination will come from the person sitting behind the camera or computer and not the equipment, but that's not what we're discussing here, from a purely technical and technological point of view the Sony sensors are better.
At the end of the day the combined equipment along with the prowess of the person operating that equipment and doing the processing of the images is what dictates whether the final image is extraordinary or not, but when it comes to equipment and my recommendations I look at the technical aspects and make recommendations. I recommend the cameras with certain Sony sensors and minimal raw manipulation because those sensors are the best from a numbers point of view. And for what it's worth (which isn't much), I've shot with Canon, Nikon, Sony, Fuji, Pentax, and ASI cameras. I'm not married to any one system, I've bought and sold more cameras and lenses and other equipment from every manufacturer than I care to ever remember. I choose what's best based on the many amazing analysis done by people like Mark, Bill Claff, Jim Kasson, Roger Cicala, and the amazing people here on CN, then I go out and test it myself. My personal testing, more often than not, tends to generate results that match those mentioned.
