Using my 50mm lens on the 450D managed 40 lights, 40 darks on LMC processed with DSS and GIMP.
Not sure about the colour with such a wide angle I have a problem aligning colours in DSS and wonder if this is too blue and whether there is a better method to get colour balancing other than getting the right white balance in the first place.
