and by the way, where i live, Auburn, Washington, i have set up my camera and taken images of Orion and found anything more than ten seconds at 300mm, f5.6 saturates the CCD. Full moon at f22 for 1/200, f22 also saturates the CCD. And i know where the geostationary satelites reside for they show up as dots in the middle of star trails. Fom the APOD, I would pick central Africa for extended sky imagery.

When i am inspired to do so, I do allow myself some levity and humor. It is not steroids, it is just opportunity.

People are invited to look at the map and see how many dots they can see.

(Shouldn't those green dots on the green map have been posted on March 17th?
Are the red & orange dots being saved for places that one cannot see the sun?)
And do the green dots indicate environmentally friendly electricity?

Too much Irish yesterday, I read your post as "low flying steroids."
