    Thanks all for the comments!

    Yes, Brad, looking at something earthly is an idea. This topic has come on me when I recently saw spots on the Sun, I was going to analyse spots' positions on the images to learn the limb rule.

    :)

    I'll definitely report my "findings".

    Warm regards,
    Tony

    The scope I use is a 3x non-inverting one.
