Hello Alan,
wow! - fascinating and thought-provoking photographs - as are always good pictures from our cosmic surroundings.
And at the same time the photos reveal to me a new side of your photographic activities, the DSLR-Canon photographer, so far I have almost entirely been exposed to your Leica-character.
Your trial-and-error-success makes me sure that we will see more astronomical photos from the ’DSLR-photographer’. We will be looking forward to seeing the results :-)
Best regards
