This community does outstanding work. We gathered in Montréal, Québec, Canada for SPIE Astronomical Telescopes + Instrumentation, the most valuable technical event for ground-based, airborne, and space-based telescopes, and their supporting instrumentation. With a strong program and an incredibly dedicated community, this event allowed researchers and engineers to share advancements, discoveries, challenges, and project updates with colleagues from around the world.
