Course Overview

What this course is designed to develop

Astrophotography is part planning, part field technique, and part data processing, and a beginner who skips any of the three ends up with noisy, blurred, or unframed results. This course walks through the full chain: reading the moon phase and forecasts to pick a clear, dark night, using the 500 and NPF rules to expose the Milky Way without trailing, capturing and blending star trails, understanding what a tracking mount and a small telescope actually do, and calibrating and stacking deep-sky frames in free software. You finish able to plan a shoot, capture clean data in the field, and turn dozens of frames into a sharp, low-noise photograph of the night sky.

Learning Outcomes

What the learner should be able to understand, build, or execute.

Plan a night shoot around moon phase, weather, light pollution, and a target's position

Configure a camera and tripod for wide-field Milky Way exposures using the NPF rule

Capture and blend star-trail sequences from a continuous frame series

Explain how tracking mounts and beginner telescopes extend exposure time and reach

Shoot calibration frames and a deep-sky light set ready for stacking

Stack and process deep-sky data in DeepSkyStacker and finish it in an editor
