These astronomy binoculars are amazing. The clarity and light gathering is far better than I expected. I have a smaller pair of high end binoculars for general use and I thought they were great.
Then I wanted to try these out, primarily for the larger / stronger Magnification of night sky objects. I was BLOWN AWAY! You can see Globular clusters, the Andromeda Galaxy, Orion Nebula with sharp, details. The fiels of view is also outstanding so the images are very ‘immersive’ with a 3D quality.
The only issue is the relative fatigue because of their weight. I have a camera tripod and once I attached it to-the sturdy screw-mount base on the Sky Master, no more dancing stars and shuddering when your arms get tired.
There are more expensive versions of these binoculars, but I don’t know if they are THAT much better. As an amateur astronomer, I have shared these with friends at Star Parties and they are amazed just how good they are.
No regrets. I am very picky about getting GOOD views, so am very happy.

I would expect more from Celestron, or perhaps Amazon is recycling returns?
When I removed the last of the packing material from around the binoculars, I heard the faint sound of something clicking, or rattling. When I turned the binoculars so the eyepieces were pointing down, I heard it again. And I heard it again when I flipped then over so the eyepieces were pointing up. When I put them in better light, I found that there was a loose screw falling back and forth in the left optical tube of the binoculars. When I looked at the objective lens in sunlight, I could see that the coating on the inside of the lens had been scratched in several places. ... I am so disappointed. I purchased these to watch some once-in-a-lifetime astronomical events that will happen soon. Now I have to wait for the binoculars to be replaced. Will I receive replacements in time? Or will I miss the events and the next time they happen is after my death? Celestron - what has happened to your quality control? ... And why did they have to be shipped all the way from Great Britain? I purchased from Amazon because it was about $100 less. Maybe I should purchase directly from Celestron - it might be that Amazon is selling seconds or returned items, and getting rid of them from where ever they have them stashed away.(ADDITION) I ordered directly from Celestron, and it was shipped from a distribution center in California. It cost more, but the product was undamaged. The package from Celestron was also in better shape. The Celestron product box from Amazon looked like it had been opened, although the inside packing appeared untouched; the packing of the Celestron product box inside the Amazon shipping package from Great Britain was poor, allowing damage to the shipping package. When I tried to return the binoculars with free shipping, one outlet of the shipping store would not take it because it was going to Great Britain, which required driving to another outlet on the other side of town. Couldn't Amazon had warned of this possibility? And again, why Great Britain? Was there no source for Amazon in the United States?I found a review on the Celestron website that described the same problem as mine. The pictures included with the review showed damage nearly identical to mine, specifically the screw on the inside edge of the objective lens and the pattern of scratches on the inside of the lens. The likeness was uncanny, reinforcing my suspicion that Amazon acquired a defective product and shipped it to another location to sell it at a lower price.Still, it does suggest that Celestron should do something about the quality control in the Chinese factory that is building its products.

La referencia a este comentario es en base a los binoculares 25*100 es un artículo ya profesional no es para principiantes es muy pesado para maniobra por lo que se necesita de un buen tripié
Tiene mucho más profundidad que los otros binoculares que tengo, y mucha más definición... El precio estaba bastante accesible y la compra a meses sin intereses fue lo que terminó a animarme
Los recomiendo mucho si les gusta la astronomia
