I always use stars 5 & 6 (E & F) in the Trapezium as a measure of seeing. In the larger apertures I look to see how clean the split is. In the smaller ones I look to see if I can split star 6. (Need to boost the magnification sometimes).

The Orion Nebula never fails to impress and really is one of the best objects in the night sky. If you have filters it is even more stunning especially with O-III but UHC works very well. H-Beta gives it a different appearance but still stunning.
