Another great image Martin! Gosh you're getting some mileage out of that 6"!!
I've also been having some dramas getting cooling all the way to -10. One of the things I've noticed with my asi2600mc is that if the cooling maxes out at 100% I get terrible hot pixels appearing everywhere (worse noise than if the cooler was off). They then promptly disappear once I set the cooler to say -5 but I've been caught out a few times and lost a stack of data. The heat haze and currents of our urban environments can be really bad too. You've done well to get this image under such difficult conditions
