If you’re looking to get a close-up view of the upcoming solar eclipses in North America, you might be considering the Celestron EclipSmart 12x50mm Porro solar Binoculars. These binoculars offer 12x magnification and have solar filters permanently built into their 50mm objective lenses. However, before making a purchase, there are a few things you should know about these binoculars.

Firstly, it’s important to note that it’s not safe to look directly at the sun through binoculars without solar filters. The Celestron EclipSmart 12x50mm binoculars meet the ISO 12312-2:2015(E) international safety standard, so you can view the sun without worry. The binoculars also have thumb pads on the underside for easy gripping and can be mounted on a tripod for added stability.

The performance of the Celestron EclipSmart 12x50mm binoculars is impressive, with detailed views of sunspots on the sun’s surface. The 50mm objective lenses provide a bright image of the solar disk, and the binoculars are capable of identifying and separating different areas of activity within sunspots. However, it’s worth noting that there may be some color fringing around the sun’s disk, but it is not distracting.

One challenge with these binoculars is holding them stable, especially at a magnification of 12x. Sitting down while using them can help reduce wobbling and blurriness. Alternatively, using a tripod adaptor jack with the binoculars can provide a steady view. However, finding the sun can be difficult with the Celestron EclipSmart 12x50mm binoculars, as the sun appears tiny in the sky and is the only thing visible through the solar filters.

Overall, the Celestron EclipSmart 12x50mm Porro Solar Binoculars offer impressive performance and safety features for viewing solar eclipses. With a bit of practice and patience, they can provide detailed close-up views of sunspots on the sun’s surface.

Definitions:

• ISO 12312-2:2015(E): An international safety standard for solar viewing devices that ensures they provide adequate protection for viewing the sun safely.
• Objective lenses: The lenses at the front of the binoculars that gather light and focus it into the eyepieces.
• Porro prism: An optical design used in binoculars that provides good contrast, clarity, and less light loss compared to roof prisms.
• Eye relief: The distance between the eyepiece and the viewer’s eye at which the entire field of view is visible.
• Magnification: The degree to which an object appears larger when viewed through binoculars or a telescope compared to when viewed with the unaided eye.
