Our Virtual NEAF 2021 Videos

Northeast Astronomy Forum (NEAF) 2021 — “the World’s Largest Astronomy & Space Expo” — is in the history books after streaming 10-hours of material on April 10th.  Tele Vue provided seven unique videos for the event and we’d like to thank all who tuned in and showed their support in the chat!

Each of our videos answers a question from one of our blog readers. If you want to review them, they’re all linked below and cued up to the question being answered.
