Great write-up Scott.

I found an older observation which a collection of all visible "stars" under 7mag skies and good but not perfect seeing. Instrument was my 27-inch with magnification of 586x. Trapezium star "G" was visible. I saw and encircle the objects 170-334, 170-337 and 159-350. I could not detect 177-341.

Last new moon I again tried some of your mentioned proplyd's.

Under 7mag skies but very bad seeing (F difficult to separate) I could steadily hold 159-350 with averted vision. 170-334 was popping in but out of view and sure visible.
One night later under 6mag skies but better seeing (G popping, F easily visible) I could saw 159-350 with direct vision and 170-334 steadily with averted vision.
