Abstract

This article from Sky & Telescope explains the significance of matching a camera's pixel size to a telescope's optics for achieving clear results in deep-sky imaging. The pixel scale, which determines the spatial resolution of an image, is discussed along with a formula for calculating it based on the camera's pixel size and the telescope's focal length. The impact of atmospheric conditions on image resolution is also explored, along with measures for evaluating the quality of seeing. The article introduces the Nyquist theorem and emphasizes the importance of finding the right pixel scale for optimal image detail. The author also mentions techniques like binning and drizzle integration to improve image resolution. [Extracted from the article]
