In this deep-dive astrophotography video, I walk through how a telescope actually works - not just the optics, but the entire imaging system. We’ll explore how focal length, aperture, sensor size, pixel size, and focal ratio all interact, and how exactly this ties in with state-of-the-art tools like BlurXTerminator.
This is a full, ground-up explanation of field of view, image scale, the image circle, sampling, and spatial frequencies — including why fast scopes need special filters, what MTF curves really tell you.
Whether you’re just starting out or rethinking your setup, this guide will help you make better-informed decisions and see through misleading specs or marketing.
