Michael,

Where did you get the image of the Earth?

Michael,
Michel Collart in France has prepared a spreadsheet for calculating the relative size of the Earth's disc on a solar image.
I've a copy of his freely available spreadsheet attached to this post.
In Photoshop or similar, you select 3 points on the edge of the Sun's disc.
Enter their X and Y coordinates in to the spreadsheet.
It will then tell you the relative size of Earth in units of pixels.
I just use a freely available image of Earth from NASA for reference.
I then scale it to the correct diameter of pixels on my images.
Hope this helps.
Clear Skies,
Michael.

That is quite stunning. About 12 years ago I bought a couple of A4 solar blockers from Astronomy Ireland. I had a pair of 25 ×100 binos. I could see lots of sunspots.. (The people in the park thought I was a weirdo!). About 2 days later I was getting out of a cab and I dropped them. It basically split it half! They are not very well built So I only use the smaller binos now. Those pictures are amazing. Stunning.
