The possibility of "hot pixels" is certainly there, Frank, depending on just what you mean by that phrase...and the behavior it describes. From www.heavens-above.com, I was expecting Aldebaran to be a little to the north and a little to the west of the moon. So I took one picture, came in, and that was what I found. The idea of spurrious results never entered my mind. I went back outside to hunt for Orion, with no success, and Sirus, with apparent success.
Now, if by "hot pixels" you mean an inconsistent behavior in the image captured by the digital camera, then that is a possibility. I took only one moon/Aldebaran photo. So I have no data to compare. If we are saying this could be digital noise, then yes; it could be.
If you mean "a set of consistently bad pixels that brighten a particular portion of every image taken" then, no. I scanned my Orion photos with great care, and I can tell you for sure there is no "bright spot" (or rather, slightly bright spot) in the various photos in the same relative place on the field of view.
"A little north and a little west" - which is what I was looking for - does not carry enough precision for me to make a judgement relative to the horns of the moon. You would be in a better place to evaluate that than me.

p.s. The one thing I WAS aware of when out taking pictures was the extremely high-flying aircraft that passed right in front of the moon. I thought to myself, "Don't take a picture yet Bob; it could be quite misleading".
