Zhumell 25x100 Tachyon Astronomy Binoculars with Case, Black

I will also write my impression, for someone it may be useful! I will start with the fact that I have been interested in optics for many years, it is my hobby, I own a telescope and three binoculars, two of them are of high quality, 8x Nikon and 10x Vortex, so I have something to compare the quality of the picture and field of view with. But lately I wanted a stronger magnification, I thought for a long time and read reviews, I could not decide 20x80 or 25x70 Celestron, after I looked into it, I immediately crossed it out because of the small field of view. Then there was a choice between this Zhumell, Celestron SkyMaster and Oberwerk Explore, all three 20x80, but there is a difference in price, besides, since I do not live in the USA, delivery to my country with customs clearance costs me an additional $ 100. I decided to stop at Zhumell, because according to reviews, it is almost the same quality as Celestron, but it is cheaper and has fully coated lenses than Celestron. I saw a lot of reviews that you can get it with bad collimation, but it did not scare me, turning the screws is not a problem for me, I did it on binoculars. In the end, I received the long-awaited parcel from Amazon, for which I thank them! No damage! Now a review of the binoculars themselves). I am very pleased with them! This turned out to be what I hoped for. Firstly, the collimation is 100% accurate. The field of view is wide, like on my 8 and 10x. The image is sharp across the entire field of view, which is important! The sharpness itself is clear and excellent! I use the binoculars for terrestrial purposes. The image is bright, at night in the dark you can see details when your eyes can’t see anything. The image detail is much better than 10x. In the end, I am so pleased with the picture that I think how much better this image can Oberwerk give for $ 270 if the Zhumell image is completely satisfactory, why overpay and for what. I have a tripod, but I hold the Zhumell (2 kg) in my hands without problems for an overview view without lingering on the object for more than 20-30 seconds. There is no big shake! For a 2-3 minute review, you can do without a tripod. But if you need to observe the object longer, then a tripod will help. This is my honest review. I am very pleased with my choice and thank you Zhumell for an inexpensive but high-quality product!!

OK so not easy to grab and run out and view. I doubt seriously if anyone is steady enough to hold these still in their hands for astronomy type viewing. I have em on an Orion Telescopes Monster parallelogram and they work pretty well. Still I get better views when I get on target and take my hands away. No vibration at all that way.The moon is awesome. Looking tonight with maybe a quarter moon we could easily see crater and mountain details and easily see the mares in the shadow.M42 is realy nice. I haven't seen this much with aging eyes in a while.4 moons of Jupiter were really clear. My minds eye thought I could see some color on the disk but I was never super clear about that.Pleiades were absolutely fantastic. They take up almost exactly the whole field of view through these and are amazing to look at. You get a depth of field through these that you would never get with one eye on a telescope. Everythings is nice and bluish.I've got or had 2.1x41s, 2x54s, 10x502, 8x60 & 20x80s binocs. Telescopes that range from the silly 35mm up to 13". I make a lot of my own stuff and I'm working on a set of DIY 100mm f4.5 binoculars that I started right before my wife bought me these. I may never finish those because these are so good I can't imagine coming close.Cons:1) They are expensive but not so much compared to other similar astro binocs. I doubt I would have bought em myself cause I would never have thought they were so much better than my 20x80s. They are.2) They are heavy. You won't freehand em and do well so plan on building or investing in a BIG mount.3) My wife thought she was getting me a birthday present but they were basically useless until we got the mount. It was $500 and she bought me that for our 31st anniversary. I was planning to build one but her's is better. Just expensive.4) The mount and binoculars are almost too heavy to run out and look at something quick. I have a bad back and I often want to go out to view but I can't justify the pain caused by totin' that mount so I have to wait for one of my boys to take em out. I want to make a permanent safe place for them on my patio so I can just go out and view. Problems to overcome...If you are the kind of person that only wants the best then these may not be for you. If you want some very good binoculars for the night sky then I think you will be happy with these. If it weren't for the costly and necessary mount I would recommend these for a first scope. You will definitely see more than I ever did with my first 5 scopes.

These arrived unusable due to double images. Unfortunately I didn't test them prior to the return window closing. I was going to toss them out when looked up how to fix columation on youtube. It isn't really that difficult to merge the images with a good tripod and a nice distant object to focus on. You will have to remove one side of the rubber grip to get to the two screws. After fixing the issue these deliver a nice image. Especially for the price. That being said, understand that all binoculars of this type are bulky and fairly heavy. Hand holding a 20X set of binoculars is not very satisfying. If you really want to hand hold binoculars with some magnification, to get pleasing results you are going to want stabilized binoculars. However you are looking at 10x the price at least.

The binoculars themselves are really quite amazing. They are much bigger than I had imagined. I knew that they were going to be big, but you really have to have them in front of you to appreciate the size and weight. You absolutely have to have a heavy duty tripod to properly use these bins. Be prepared to spend another $100 or more on that. These are definitely not for casual, handheld use. Great views. Great lenses. My only complaint would be the case that they come in. It looks good, but its looks are deceiving. Mine was completely broken on one side, like it had been dropped. Or sat on. Not a good first impression for sure. Thankfully, the bins were not damaged.
