Hi Jahn,
I culled the lights down from 77 to 60 of the best. It made a substantial improvement. Please see image attached. I believe if I centre the eta carina nebula within my frame so that it is not at the edge and I introduce more data through narrow band work I could get a half decent image. A fair amount of wobble was introduced to some of the light sub frames when I walked around the deck on which the rig was set up (I need the elevation to see over the neighbours trees). I'll also save my pennies for an apo telescope.
Cheers Kanga (Peter).
