seeing rating scale for Planetary imaging

[Robert_T]

Hi All, many of you have probably already seen this. I came across it by accident on Damien Peach's web-site. The pickering seeing scale from 1-10 with actual video simulations of what a focussed star will look like at different seeing conditions. Looking at these I may have to review my seeing ratings down a notch or even two. Don't think I've ever seen beyond 7 on this view, and the last couple of months it's been "1" with a high of "3"

thanks robert, enlightening

Yep. Been going by the pickering scale for awhile now. I'll stick an eyepiece in & 'call' the seeing before an imaging session.

He obviously hasn't been to SE Qld in May. There are no negative numbers.

our main problem in sydney atm is transparency...

Let me guess, Ving... you're seeing through the stars and the whole lot???

There you have it, you need a 5" scope to rate it this way or be aware of how your current conditions would look compared to a 5" scope.
