Binoculars are a fantastic tool for amateur astronomy, offering a simple and affordable way to explore the night sky. They provide a wide field of view, making it easier to locate celestial objects like star clusters, the Milky Way, and large nebulae. Unlike telescopes, binoculars are portable, require no setup, and can be used comfortably without additional accessories. Their two-eyed viewing also enhances depth perception and image brightness, making stargazing a more immersive experience for beginners or anyone looking for a casual way to observe the stars.

Celestron UpClose Range

The Celestron UpClose binocular range offers a variety of magnifications and apertures tailored to different viewing needs. These include 7x35, 8x40, 10x50, 16x32, and 20x50 models. The lower magnifications like the 7x35 and 8x40 are great for wide-field views, making them suitable for birdwatching and general nature observations. The higher magnification models, such as the 16x32 and 20x50, provide more detailed views but may be harder to stabilise without a tripod. We chose the 10x50 model because it strikes an important balance, offering solid magnification and a 50mm aperture for good light-gathering capability. This makes them a popular choice for amateur astronomers.

For astronomy, the 10x50 model is often favoured for its bright, clear image and relatively stable handheld use. However, all models in this range share a similar build quality, using BK-7 prisms and basic optical coatings, which make them affordable but result in some edge softness and chromatic aberration under challenging light conditions. The Celestron UpClose range of binoculars offers budget-friendly optics suitable for beginner astronomers. However, the overall build quality and optical features reflect their affordability.

Celestron UpClose First Generation 10x50

The initial version of the UpClose 10x50 binoculars offers a relatively clear view considering their cost, but they have shortcomings in crucial aspects for astronomy. The BK-7 prisms they use do not provide the same level of clarity as higher-quality BaK-4 glass, resulting in some blurriness at the edges of the field of view. Users might observe minor chromatic aberrations near bright objects such as the moon, although this occurrence is less pronounced than anticipated for binoculars in this price category. While the focusing capability is suitable for casual sky observation, these binoculars are not intended for serious astronomical use. They do not have waterproofing or fog resistance, which could be a disadvantage in cold or humid conditions. Nevertheless, we have found them to be a useful addition to our equipment and observation tools. They make it easy for us to locate targets and have been helpful during recent sunrise observations of comet C/2023 A3 (Tsuchinshan-ATLAS). Without them, we would have been unable to visually observe the comet with the naked eye in our area. Their affordability also means that we are less concerned about the conditions in which we use them, unlike with more expensive gear.

Celestron UpClose G2 10x50 (Second Generation)

The UpClose G2 10x50 (second generation) made a few improvements over its predecessor. The build, while still basic, is slightly more durable due to the rubber-armoured aluminium body, though it’s not waterproof or nitrogen-purged. Optically, they use the same BK-7 prisms, and internet reviews report that the performance remains similar with bright and colourful images but still some distortion at the edges. A key downside of the G2 version is its 12mm eye relief, which can be uncomfortable, especially for eyeglass wearers, and the eyecups feel loose, reducing their durability. Performance-wise, the G2 excels for its price, offering good views of star clusters and planets like Jupiter. However, the edge softness and occasional glare from bright light sources make them less than ideal for more serious stargazing.

Comparison: First Generation vs G2

The first-generation UpClose 10x50 and the G2 share many of the same core features, such as the optical system and magnification, but the G2 has a slight edge in build quality. The rubber armouring on the G2 provides better grip and protection, while the accessories are still minimal, with basic lens caps and a carry case for both. In terms of optical performance, both generations show similar limitations, particularly at the edges of the field of view and in dealing with bright lights.

Ultimately, while these binoculars can offer a pleasant introduction to stargazing, particularly with wide views of star fields or clusters, they might disappoint those seeking more detailed, high-quality astronomical observations. If you're looking for an entry-level pair for casual use and don’t wear glasses, the G2 10x50 could be a reasonable option. However, for more serious observing, upgrading to binoculars with BaK-4 prisms or better waterproofing might be necessary.

Conclusion

For amateur astronomers, binoculars are a fantastic first step into the night sky. They are portable, easy to use, and offer a wide field of view, which makes it easier to locate and appreciate larger celestial objects such as star clusters, nebulae, and even the Milky Way. They don’t require the setup or maintenance of a telescope, making them perfect for beginners or casual stargazers. Additionally, binoculars like the Celestron UpClose 10x50 offer enough magnification to get meaningful detail on the moon and other bright objects while being relatively easy to hold steady without a tripod.

After reviewing the Celestron UpClose 10x50 binoculars, both the first generation and UpClose G2, I have a few conclusions based on their suitability for amateur astronomers. If you’re new to stargazing and looking for an affordable entry point, the first generation UpClose 10x50 offers reasonable value for money. While they might not have the high-end optics of more expensive models, they are capable of providing decent views of wide star clusters, the moon, and larger celestial objects. That said, they do suffer from some edge softness and chromatic aberration. The build quality is functional but not rugged, so handle with care if you’re frequently outdoors.

The UpClose G2 (second generation) is an improvement in terms of design. The rubber armour makes them easier to grip, and though the optics are similar to the first generation, they feel slightly more robust in hand. The image quality remains comparable, with the same minor optical flaws like slight blurring at the edges and some colour fringing around bright objects. However, these are small trade-offs given their price point, and they still offer good performance for casual astronomy, especially for large star fields and the moon. Overall, the G2 10x50 binoculars are better suited for those looking for a budget-friendly, durable option.

In conclusion, I’d recommend the UpClose G2 10x50 if you’re seeking a slight upgrade in design and durability over the first generation, but both models are reasonable choices for someone starting out in astronomy. If you’re after a versatile and low-maintenance tool, binoculars are an excellent choice. Just keep in mind that for more detailed observations, upgrading to higher-end binoculars or a telescope may be in your future.
