That's my usual assumption -- 0.2 RMS means I did something wrong:)?
I'm certain that it was a true value though as the images showed way more detail than the night before or after, and I did not change a single setting from one night to the next. -- at least until I started trying to fix the elongation.?
The stars were also much sharper that night, but they were elongated never the less.?
