On another point here - your M42 image shows that you have your colour filters mislabelled. Take your camera off, have a torch, set it to red, do a 30 sec exposure and shine the torch on the resulting filter selection. Is it red or something else? Do the same for the rest and make sure your software has them correctly labelled. M42 is reddish not blue/magenta like that.
