I looked at HH 222 the waterfall last week after viewing NGC 1999. I must say this is a difficult object. The only part that I could see was the small brighter patch near the star that I have marked in the image below. It was seen as small extremely dim patch with AV only. I tried several filters and high and low power but it did not help it any. The best view that night was with a 10MM ZAO @ 488X unfiltered. The waterfall shape of this nebula was NOT seen.
