Pete, where do you live ?
You always seem to have a nice sky in your Great Britain to take fine
pictures, and here it's clouds and rain

Right on the south coast.

OK, I move asap )

I excuse the presentation... Very interesting picture. Indeed the ion
tail is very long, and what's surprising is that it is more visible
than the gas tail.

I think that the ion tail and gas tail are the same thing Norbert (the
ion tail is sometimes called the gas tail). You mean the dust tail I
think.

Yes, I was talking about the dust tail. Thank you for the correction.

I believe the reason for this is simply line of sight. We're
looking down the dust tail but perpendicular to the ion tail. Hence
the ion tail appears long and thin, while the dust tail appears short
and stubby.

This seems as a good and simple explanation. Thanks Pete.
