I've mentioned several times on this forum having seen Trap. G, H1 & H2 (not I) from Sydney in 2013 with my 17.5". I fluked a night of staggering stable seeing and surprisingly good transparency. The image I saw had me scurrying to find info on the Trapezium- there is actually very little info about the fainter stars in this open cluster, and there are very few deep photos of the Trapezium. I would guess because most people just don't know beyond the first six stars of the Trapezium and don't see the challenge that imaging the Trapezium presents. The nebula takes all the glory, but the little nuggets within it are next to totally unknown.

Seeing these fainter stars needs all your ducks to align:
* aperture
* good scope
* excellent seeing
* good transparency
* good vision

Hell of a set.

The sketch below was done at approx 200X.

PS, following a request of mine back in 2015 for photos of the Trapezium, Dennis provided this amazing work of his: http://www.iceinspace.com.au/forum/s...ad.php?t=25156
