Nice work, Wes!

The Trapezium, being an open cluster, takes magnification very well. If you can, have another go at the Trapezium itself this time (it's 47' in size). There are MORE than 6 stars in it. One night of surprisingly steady seeing from my backyard in Sydney, using my 17.5" dob I managed to see not only Trap. A, B, C, D, E & F, but also G, H, & I at 200X.

The Trapezium itself as a unique object is just not targeted very much. It is totally overshadowed by the nebula it lights up. But the Trap. presents quite a technical challenge for photographers because large dynamic range between the stars that form the cluster.

And of course, knowing this now, one may also like to revisit the Trapezium visually, pushing up the magnification to challenge the optical quality of one's scope to resolve the fainter component stars beyond the 6 brighter stars. Aperture of larger than 10" is necessary.
