Bert, it's been great seeing your journey with fast wide field optics and CCD acreage but....
.... I'd suggest you don't push the data so hard..to the point it looks like Tech Pan 2415?
Martin (Pugh) does this sublimely....crafty bugger...but I have no idea how he does it.
anyway I digress... Smooth the data a little: shadows and highlights should show a gradual transition and structure rather than a stark contrast.
Just my 2 cents worth
