compared MallinCam images

When attempting to verify stars in the field with Messier 51, the Whirlpool, against software, I was getting thrown off a little by points to the right of the two galaxies. It was only later, when I moved the telescope slightly, that I noticed the two points did not move. Hot pixels on the MallinCam chip! So a comparison from in order. I reviewed the images from June and July.

From June 11:

And then from July 2:

Ah ha! Same green pixels in the same locations in my two M51 images...
