SUMMARY
This discussion focuses on simulating star images for testing a star tracker in a student satellite project. The key challenge is ensuring that rays entering the star tracker are parallel, mimicking the conditions of stars at infinity. The use of a collimator is essential for achieving this, and the thin lens formula, $$\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$$, is critical for understanding the relationship between the lens and the LCD display. Additionally, the discussion addresses potential aberrations when capturing images with and without a collimator and emphasizes the importance of practical experimentation.
