Hi
Thanks for the reply. It possibly would help less experienced amateurs if the example explained if the video was a representation of good , average or bad seeing. For my location I would class the example given as good seeing conditions and would love to have that seeing more often. My average is a lot worse than that thanks to the local topography but a few times a year , during planet season hopefully, conditions align and steady seeing and resultant avi's , like your example, can be obtained.
There was a link to Damian Peach's website a few years ago that gave an example of The Pickering Scale and the different levels of astronomical seeing.
