Orion's sword and belt are popular areas, so to go off the beaten track a bit I went for his head: SH2-264 in Ha. Orion must have had quite an ego - this thing is huge! I used the Epsilon 180 and STL11K which has a FOV of 245x168 minutes or about 4x2.8 degrees and still could only get about 1/4 of it (the NW 1/4)
