Thought I would send this one in, as it seems to be a topic of
discussion at the moment.  This was my first observation of the Crab,
just less than 4 years ago, when all I had was a 'supermarket' 4.5",
but in much better skies than where I am now.  I was relatively
inexperienced (perhaps 2 years), and noted that it was quite faint,
with no detail visible, except a definite elliptical shape and a
greenish tinge.  To be honest, in the relatively poor sky conditions
which I usually have now, it looks almost the same as this in a 220mm
f/5, unless I travel further afield.
