Trapezium

Hi. Brian Tung has a nice image of the Trapezium
http://astro.isi.edu/notes/trapezium.html. Question. Does anyone have
the same thing, but with N/S, E/W flip buttons? So you can go from a
refractor or Schimt-Cassegrain to a Newtonian. Just wondering.

I think Brian's image is for a S-C, North is up, West is left. With a
Newtonian, I think South is up, West is left...Dennis

As it states in the accompanying text, north is up, east is left. It
is therefore the same orientation as usually seen in paper star atlases.

Most image viewers will flip an image horizontally or vertically. Open
my map in one of them.

This is what I had in mind: http://www.stargazing.net/mas/trap.htm

Hey, pretty slick. Go ahead and put it up--knock yourself out.

Already in the JavaScript Sheet section. Thanks.

If you get a chance, look around our web site. It's really geared for
the observer...Dennis.
