Theta Orionis: Website focus on Trapezium

I came across a really nice website dedicated to the trapezium while
researching the magnitudes of the e and f stars. FYI, they are mag
10.3 and 10.2 respectively. I had no problem resolving either in the
12"; don't remember ever seeing f in the 8". Well maybe once. My skies
are bad and I don't travel much.

Anyway, for any interested, here it is:

The high rez ESO shot of the Trapezium is impressive! Thanks for the
link!

Interesting site, thanks. Does anyone know the separation between C and
F? With my old C8 I've seen both E and F on good nights. Given their
brightness it's surprising how infrequently I've bagged them.

I'd estimate it at about 25 arcseconds.

Sorry, bad typo: Make that about 5 arcseconds.

Both E and F are fairly easy in an 8 inch from the Florida Keys. Not
so easy from my home in MA.

Both e and f are routinely visible in my 8" f/6. It would be VERY unusual
if you couldn't see them both. And with decent seeing, both are visible in
my 94mm APO...

In all my scopes above 8", the game is to see what the LOWEST magnification
is that will reveal them both... My guess is that here, on a decent night,
an 80mm or even smaller scope, can resolve e & f fairly frequently...

Well rub it in why don't you. :-)

We should have clear skies tonight. Me and the 8" scope or going for
a little ride tonight. I have a spot that I found about 30 miles west
of the New Orleans city limits (westbank) where skies are not terribly
polluted. I'll try again from my house and again when I get there for
comparisons sake.
