Thanks for the comments! Yes, I am slowly pondering other features that I can add (within my abilities!) and 'images' is something that I have thought about -- if I can find a net resource for them.

I also like the 'solar system' view -- but please realize that the image is being generated on the web -- not be my application! I have been amazed and pleased at the free resources out there (images/data) that can do a far better job than my own python program. I am currently working out adding even more!
