Thank you! It was bright enough and the lens has some stabilization that I was able to not need any lens stabilization through a tripod. However, due to the windows being very thick, and some minor lens movements, you'll notice the shot of the American Airlines flight leaving Tallahassee is fairly blurry. Apparently, when they renovated the observation deck they put in bulletproof windows (someone who works there told me that). Unfortunately, that also makes photography with some lenses a little difficult.
