Celestron SkyMaster Pro ED 7 x 50MM Porro Binoculars

The Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, or color fringing. This means you get razor-sharp, high-contrast views without the distracting purple or yellow halos around bright objects like stars, planets, or the Moon.

They excel on these targets. Because the ED glass corrects for chromatic aberration, the limb of the Moon appears sharp and crisp, and you can resolve the cloud bands of Jupiter with excellent color fidelity and contrast, free from the color fringing that plagues standard binoculars.

Yes, at 44.3 oz (1,255g), they have considerable mass. While they can be hand-held for short periods, their weight makes a tripod or monopod highly recommended for astronomical viewing to prevent arm fatigue and provide a stable image. They are equipped with a standard tripod adapter mount.

Yes. This is a key feature for astronomers. The eyepieces are threaded to accept standard 1.25" filters. This allows you to use light pollution or nebula filters (like UHC and O-III) to significantly enhance views of deep-sky objects, a capability almost exclusive to these binoculars.

The wide 7.8° field of view is perfect for large objects like the Andromeda Galaxy. You will be able to frame the galaxy's bright core and its extensive faint outer arms within a single field, along with its two companion galaxies, M32 and M110. This provides a rich, contextual view that higher-magnification instruments cannot offer.

Absolutely. The 20.8mm eye relief is exceptionally long, providing a comfortable and complete field of view for virtually all eyeglass wearers. You can simply twist down the retractable eyecups and observe without needing to remove your glasses.
