SkyCal Focus and Collimation Tool

SkyCal is a specialized software tool designed to assist astronomers in achieving precise focus and collimation. Accurate focus and collimation are essential for astrophotography. Even small misalignments in a telescope’s optics can lead to blurred or distorted star images, reduced contrast, and loss of detail in deep-sky objects. SkyCal provides visual overlays, error measurements, and optional voice feedback to guide adjustments, making the process easier, repeatable, and more reliable.
