In the late 1950's, John Dobson looked
through a telescope at the Moon and immediately said, "everyone's got to see this!" and began making large telescopes
and wheeling them down the streets of San Francisco to show "everyone" the Moon and planets. “We
aren’t born in San Francisco, we aren’t born in California, we aren’t born in the United
States, we aren’t even born on Earth – we’re born into this UNIVERSE, and we need to know about it!”
John understood that the first
step in learning out this Universe was to see it and to show it to others. That is the whole purpose of ISAN; to get those
with scopes around the world to take them out and show others where they were born.
We ask all amateurs to join us on this one night to celebrate the beauty of our Universe,
to celebrate John's vision, and to have some fun with your local community.
When we started ISAN, I don't think Facebook existed
but it does now and that has made it easier - we no longer have to ask you to register your event and follow up with photos
and details - just post on your own Facebook page and share it with ours! facebook.com/sidewalkastro
We look forward to seeing what a great time everyone has on April 20th! Feel free
to copy and use our logo and ISAN artwork for flyers or other promotional materials. We have resources here on our site for
those new to sidewalk/public astronomy and if you have any questions, just send us an email at email@example.com
and if you need the artwork in a larger file, just let us know.
