Hi,
I left my 120ED out for half an hour, which usually does the trick. It is slightly undercorrected which I combat a bit with some glass path in the form of a prism diagonal.
If I recall correctly on this example the crayford was ok - my ED 80 needed a lot of crayford love when I bought it, but now also very smooth.
Sure, an eagle is a bit easier to see than a magpie... but the chicks are about the same size.
Since seeing was the limiting factor, I guess the a 150 would not have fared better...
