As the song goes "What a difference a day makes".
Same proms but look how much they've changed!
I added an Earth scale to the image. I think I calculated it correctly (based on earth being 1/400 of the angular scale) but it still looks small to me.
Seeing was far worse today so I captured double the number of frames & dumped half.
update: Nytecam on Cloudynights spotted that the Earth was the wrong size - it's actually 1/110 the diameter of the sun. oops! updated now.
Thanks,
Trev
