Hey, last Saturday I was convinced that I'm seeing spiral
structure in M51 in my 8". And that was under much less
than ideal conditions - not very good transparency and some
light pollution.

So, now I have to ask myself: Do I have really good eyes or
really good imagination? :-)

....but also: Does it make difference which one is the case?
