My last 18" observation of Pal 2 is quite similar to your 16" notes. What have others seen?

Pal 2 was immediately picked up at 285x as a faint, fairly small, roundish glow, ~1.5' diameter. Easily visible with averted vision and could be held continuously without difficulty. Very weakly concentrated with a very small brighter core or knot that seemed offset from the geometric center. SQM-L 21.55
