Message from Sky & Telescope

The AAS staff (including staff of Sky and Telescope) are working remotely from their homes to support the social distancing efforts to contain COVID 19. While we are all working to support the S&T community, there may be delays in responding during this time. If you have a question or concern, please contact Camillia Taylor at [email protected].

This is a difficult time for the entire United States. Aero, our fulfillment partner, is based in Ohio. Aero provides fulfillment services for P&G. While they will continue to fulfill our orders, there may be a delay in shipping our products because they must give priority to medical, personal healthcare, and cleaning and sanitization products.
