Welcome to NASF3!

Meet NASF3
New Amsterdam Science Fiction & Fantasy Fandom is a non-profit organization that sponsored the first HELIOsphere in March of 2017.

Our Guests of Honor were Danielle Ackley McPhail, David Gerrold, and Jacqueline Carey. With the uniquely talented  Heidi Hooper as our Featured Artist. Chuck Gannon was our Special guest author.

This unique New York City area convention was such a success and that we launched Heliosphere 2018. GOH’s featured Charles E. Gannon with Eric Flint presenting the “1632” Mini-Con. Other GOH’s were Cecilia Tan and Mark Oshiro. And as our Featured Artist, we hosted the remarkable Tom Kidd.

Heliosphere 2019 moved the Convention date to April 5 – 7th and had much better weather, making travel a lot easier for our members and Guests. GOH’s were, Laura Antoniou, Charlie Jane Anders, Tom Smith, and Alan F. Beck as our Featured Artist.

HELIOsphere 2020 will be held April 3-5 in Tarrytown, NY
The aim of our organization is not only to present a successful annual Science Fiction convention, we also want to serve as a home for Science Fiction and Fantasy fans and organized Sci-Fi fandom in the greater NYC area.

Heliosphere 2020. Guests of Honor are Claudia Christian, Morgan Grant Buchanan, Peter David, and Kathleen O’Shea David and company as our Featured Artist.
