Mark - is that a dew shield extending the 400L length OR is the 400L that big?
Nice to hear good things about that Astrotrac.
If you don't want go-to/etc seems perfect for widefield portable set-up's, like in backpacking to remote/dark areas.
I've sunk my $$ into gear for this year, but for future that is on my short list.
It is the Lens Hood yes, Lol
But dont get me wrong..This Lens Is HUGE!!! And heavy!
