Unfortunately for photography, there's a real tradeoff between magnification
and maximum exposure without star trailing. I've taken rolls of this thing
so far, and my best results seem to be using a normal lens to just slightly
telephoto (i.e 50-90mm) range. Much longer than that, and star trailing
begins to be evident at fairly short exposures, and you lose comet
detail.

That is, of course, for a camera on a tripod. I'm hoping to find time
to build a barn door tonight...

Hate to keep harping on this, but get out to a dark site, the tail
is very obvious to the naked eye.
