Had to have another look (read drool) at this Ray...seriously man, this is a friggin amazing result mate and to think it was achieved with an inexpensive fast 10" newt and a small inexpensive camera and modest mount is really eye opening. You have clearly got your collimation and image plane tilt spot on and the use of only good seeing data and some smart processing shows that spending $50K+ on a scope and mount or even the need for long FL is indeed not necessary, one just needs to know how to tune their scope and then image with it under really good conditions....
RIGHT!! you and me, now, moving to the mountains in Chile we are...so every night has good seeing (not the Aussie version)...imagine what we could do

..of course while it is "o-k" as is, you will have to help me tune my scope to the same level of perfection as yours though
