Thanks guys. I was quite surprised to get so much data from such a light polluted place but the integration time is quite long.

You are right, the darks match the lights and the biases are not needed. But the flats still need either dark flats or biases.
Alex, few of us made our own cameras based on the Sony ICX453AQ CCD sensor, similar to QHY8Pro. There is a link to the build thread in my signature.
I have to say I am quite happy to see how well the camera performed, we are still working on optimising the cooling.
