The Best Lens for Astrophotography and Zoom: A Budget-Friendly Guide

Embarking on astrophotography with a budget constraint can feel daunting, but with the right lens, you can capture stunning images without breaking the bank. Whether you aim to capture the vast expanse of the night sky or delve into the details of celestial objects, the choice of lens will significantly impact your photography journey. In this guide, we will explore the best options for a beginner on a modest budget, focusing on a Canon 100D, with a price range of ￡100 to ￡200. We will also delve into the nuances of choosing the perfect lens for both general astrophotography and specific star photography.

Understanding the Needs of Astrophotography

True deep-space astrophotography often requires a long telephoto lens, typically between 600mm to 1200mm, or even longer with an extender. However, for those capturing the Milky Way, a wide-angle lens, typically no longer than 24mm, is ideal. A lens with a wider maximum aperture and a faster shutter speed will produce clearer star images, especially when using high ISO settings.

Considering Your Current Equipment: Canon 100D

With a smaller-than-full-size sensor, your Canon 100D may benefit from a specific lens that optimally captures the details of the celestial objects you are interested in. A lens that strikes a balance between quality and affordability is crucial.

Budget-Friendly Lens Options for Astrophotography

### Prime Lenses vs. Zoom Lenses

Prime lenses, which have a fixed focal length, often outperform zoom lenses in terms of quality and affordability. They are also lighter and generally cheaper. While zoom lenses offer more flexibility, they may not always match the performance and value of prime lenses. For astrophotography, a prime lens with a wide maximum aperture, such as f/2.8 or faster, is highly recommended.

Recommendations for a ￡100-￡200 Budget

1. Vivitar 500mm f/8.0 Telephoto Lens T Mount White
This lens, though not a prime lens, can provide a good starting point for capturing detailed images of the Moon, Jupiter, and other celestial bodies. It is available for around ￡150 and can be a valuable addition to your astrophotography kit. However, it may not be ideal for capturing the Milky Way due to its narrow field of view.

2. Used Canon EF 35mm f/2.8 II
This prime lens, often selling for around ￡100 second-hand, is a versatile option that essentially functions as a wide-angle lens for astrophotography. It can capture stunning wide-angle nightscapes, including the Milky Way, with its f/2.8 aperture, enabling clear images even at higher ISO settings.

3. Samyang 50mm f/1.4
If you are looking for a more affordable option within the budget, the Samyang 50mm f/1.4 lens, priced around ￡150, is a standout choice. It offers an excellent balance of affordability and quality, making it a reliable contender for both wide-angle and deep-space astrophotography.

Planning Your Photography

### What Lens to Use for What Scenario

For those interested in capturing large areas of the sky, a prime lens like the Samyang 50mm or the used Canon EF 35mm f/2.8 II can be a practical choice. Conversely, if you wish to photograph specific objects—such as the Moon, planets, or asteroids—a telephoto lens like the Vivitar 500mm f/8.0 or a longer prime lens would be more suitable.

### Shooting Tips

Use a Tripod: A sturdy tripod is essential for astrophotography to avoid blur from shaking. Consider one that is specifically designed for long exposures. Choose the Right Time: Nighttime with minimal light pollution is ideal. A moonless night or a dark sky is essential for capturing fine details. Experiment: Try different settings and compositions to find what works best for your particular location and equipment. Focus Carefully: Use the live view and manual focus to ensure sharp images, especially with longer focal lengths. Post-Processing: While the lenses listed offer great quality, post-processing can help enhance the final images, bringing out details and colors that might not be immediately visible.

Final Thoughts

Astrophotography can be a rewarding hobby, and with the right lens, you can capture incredible moments from the night sky. Whether you are a beginner with a Canon 100D or a seasoned photographer looking to refine your skills, choosing the correct lens is crucial. By considering your budget, focal length, and the specific astronomical object you wish to photograph, you can make the best choice for your needs. Happy shooting!
