Question:

Is it feasible to capture a clear image of the ISS with a smartphone camera during its transit?

Answer:

Smartphone cameras have advanced significantly, offering higher resolution and better low-light performance than ever before. These improvements make it possible to photograph the ISS, especially during twilight when the station is illuminated by the sun against a darker sky. However, there are several factors to consider:

1. Timing is Everything

The ISS transits can be swift, often taking only a few minutes to cross the sky. Using apps or websites that predict ISS transits can help you plan and be ready at the right moment.

2. Stability is Key

A stable platform is essential to avoid blurry images. A tripod with a smartphone adapter can greatly improve the quality of your photos.

3. Zoom Capabilities

While smartphones can capture the ISS, their zoom capabilities are limited. The station will appear as a small dot moving across the sky. For more detailed images, additional optical zoom lenses compatible with smartphones are recommended.

4. Manual Controls

Many smartphones offer manual controls or ‘pro’ modes that allow you to adjust settings such as ISO, exposure time, and focus. Tweaking these settings can help capture the ISS more clearly.

5. Post-Processing

Even if the image isn’t perfect, photo editing apps can enhance clarity, contrast, and detail after the fact.

In Conclusion

While professional equipment will yield better results, it is indeed feasible to photograph the ISS with a smartphone during its transit. The key is preparation, stability, and making the best use of the technology at hand. With patience and practice, you can capture that awe-inspiring moment when the ISS glides across the heavens.
