I recall another great act of gratitude when a child approached me after a show and gave me a quarter. First he said, "here's a nickel" and put it in my hand. Not looking at it, I said, "yes it is". Then he said, "no, I mean, it's a quarter". I looked more carefully and corrected myself. "Yes. A quarter." Then the boy said, "It's for you. Thanks for the show." I accepted graciously. One doesn't turn down a gift or reject a gesture of thanks. At the time, this was the most I'd ever been paid for show, and my friends assured me that I was probably worth every penny.
My one regret in shows is that I don't have an opportunity to correct my errors. I try to present my own photos so that I can show people honestly what I saw, though sometimes I'm mistaken as to what it was. Such was the case with a photo I took on slide film around ten years ago. I was tracking the asteroid Ceres, and on one of the nights, something passed through my field of view (click or double click to enlarge the image):
At the time, I thought that whatever caused the striek (a plane or satelite), I was impressed that it happened to intersect three stars, and I made this comment in a few presentations. Later, I realized my error: the plane or satellite also created the bright white star-like images on the film. Notice how evenly spaced and of similar brightness they are, and that two appear to have a dimmer companion at the same position.
With this lesson in mind, I dismissed a photo taken last month as a result of the same effect.
Faint erratic meteor, or blinking object?

Here's a close up. Notice that the striek passes through several stars -- I was very suspicious.
Fortunately, I took more than one image. By switching the view between these last two images, I could see that the stars crossed by the meteor appear in the picture below taken a few minutes later:
It is a meteor!
