|
Our group finally caught up with Comet 2006 M4 from a light-polluted school
site in south Texas. Very round, large, and soft coma - looked like maybe
10-15 arcminutes across, but no real tail. Though right in the neighborhood
of M13, SWAN was larger and more distinct. Used everything from an 80mm
refractor to a 12 inch Dob, and didn't see appreciable differences in
structure. The schoolkids thought it was cool this is a hyperbolic versus
periodic comet, and that it may never pass this way again.

exact same here- I was disappointed to see no hint of a tail. A fellow
club member got an incredible photo of it with his 10" lx200 - bright
green nucleus and long thin tail - his photo is the best Ive seen anywhere
on the net - but visually it shows no tail ???

It's there, but it is very faint and seen only with averted vision under
a dark sky.
