Hi folks,
recently i revisited the parachute. This time seeing allowed magnification around 700x in my 12". The elongation was visible in correct position angle :-)
It took quite some concentration but all in all it was easy to reproduce the elongation.
NELM around 6m8, humidity 60-70%. 1550m above sea level, bavarian alps.

Just got back from an observing night on the 82" at the McDonald. We observed the parachute under pretty good skies. In the 41mm Pan (400x) the a,b and c components formed a nice little curve with a and b occasionally split. Bumping up the power to 1300x, and a little tweaking on focus to chase the seeing, c could be split as well. When c was split d became visible as a soft little glow.
