Hmm, it seems someone forgot to read the IIS “How to image Mercury” article at:

which suggests:
“Viewing a notebook display and trying to focus on a small black dot will be nigh impossible in full daylight, so shield the notebook computer from bright daylight. I plan to use my portable observing hutch which has a curtain, making the inside reasonably dark. You can use a deep cardboard box. Make sure the open end of the box is facing away from the Sun”.

Thanks Dennis. I read your article with great interest, and found it very informative.
Thanks! I did take notice of it too, because what you don't see in that photo of my little setup is the shaded area behind me under the roof of the pergola. I just had it sitting on the chair when I took the pic. Couldn't see didly-squat there! Besides... what sun? LOL!
What I am having problems with, however, is getting the ToUcam to fucus on-screen properly. Because I can't get its CCD array to line up with the focal point of any EP I have when sitting in the flip-mirror, I have no choice but to focus via the on-screen image. I just can't get good focus....at all. Am I doing something wrong (rhetorical question...)?
Cheers
Chris
