Diego, Congrats. Now your mission impossible is (and the Secretary will disavow all knowledge of your actions should you be caught) to catch the different colors on each side of the "loop". Assuming the overall shape is that of a diamond ring, with the Trapezium area the diamond, the inside of the ring is a different color on one side of the Trapezium than it is on the other. I've seen one side as "rosy-hued" (i.e.pinkish) and the other as a shade of "peach". both of these colors are in the nebulosity inside the "ring". And you'll need a dark night with clear skies (rare, recently). A very large scope (28") shows the bright "arcs" on either side of the Trapezium (the brightest parts of the "ring") to have a reddish glow, but I have never seen this in a scope smaller than 17.5". The peach and rose hues I mention are seeable in your 6" from a dark site. I've seen them in 90mm, as I mentioned, but that was from an exceptionally dark site. Good luck. [Next summer, try for color in the Dumbbell (M27). when it's at the zenith, the "bow-tie" sometimes appears greenish, and the "football" (the fainter sections at right angles to the "bow-tie") appear rose-colored. Use a decent amount of magnification, but no filter.] Double Good Luck!
