It has been windy for several days here, and tonight it got down to a light breeze.  The moon was ok and clear, and I got to use my new ES 20 mm eyepiece.  But it seemed like I could just not get things focused other than the moon.  Did I just have my first bad seeing evening?

With ~55 m/sec jet stream in Goodland Kansas and satellite showing movement of cold air from north, I would expect it to be a terrible night seeing wise.  Probably hard to get the scope to acclimate as well if temps were falling fast.

Ok, I appreciate that information.  The scope was outside for 2 1/2 hours overall.

Astrospheric is a wonderful forecast tool that includes estimates on transparency and seeing.

I use it all the time.

Get used to it. It makes the good night very special!

I second that. I've been using it here as well and it seems pretty accurate in the handful of times I have used it for my location. I ended up subscribing and paying the $.99 a month to support development, receive weather alerts and to get rid of ads. I hate ads!

Smoke from the fires out west have been causing a lot of bad skies lately. That doesn't show up in any of the 

sky forecasts as far as I know.

Astropheric takes it into account in the transparency forecast.
