Why is it important to check for lens aberrations?
—Lens aberrations, such as coma and astigmatism, can affect the quality of your images, especially in astrophotography. By checking for these aberrations, you can ensure the lens performs well in capturing pinpoint stars and minimal distortion.
How does vignetting affect image quality?
—Vignetting can darken the edges of your images, reducing image quality and potentially adding noise. It is particularly important to assess vignetting in astrophotography as it can affect the uniformity of your image and the details in the corners.
Why should I consider buying used lenses?
—Used lenses can often be more affordable than new ones, allowing you to save money. Just make sure to purchase from reputable sources, like MPB, who provide warranties and thorough checks on the used equipment they sell.
How can I assess the performance of a lens through sample images?
—By looking at sample images from astrophotographers on websites like Astrobin and Flickr, you can get a better idea of a lens's capabilities in capturing the night sky. Look for examples that showcase the lens's performance in areas like coma, astigmatism, and vignetting.
Is it possible to try a lens before buying it?
—Yes, you can try a lens before buying it through rental services or by purchasing from reputable sources with a return policy. This allows you to test the lens in real-world scenarios and ensure it meets your needs before making a final decision.
