The new Oberwerk 25x100mm Deluxe is ideal for serious binocular astronomy or long-range terrestrial viewing on a budget. avialable in your choice of (CF (center-focus) or IF (individual focus).  The CF model is the largest and most-powerful binocular on the market that has center-focus, which is a big advantage when viewing a moving target. New prism mounting system uses precision floating plates (as found on our Ultra Series), which do a better job of maintaining alignment than common prism-tilt systems. Features full broadband multi-coating (all air-to-glass surfaces, including prisms), all-metal waterproof construction with rubber armor, braced and hinged objective tubes, built-in mount. This binocular has a 2.4° field of view, with very good sharpness across the entire field.

    I ordered a package which included 25x100mm Oberwerk Deluxe binoculars, Universal Astronomics T-Mount and the standard (tall) wooden tripod (“cosmetic blem” model). All three boxes arrived the same day, eight days after placing the order. Everything was in excellent shape. Tripod is superb, I don’t see any “cosmetic blems”. T-Mount is light with smooth motions and there is very little vibration when moving the mount… fit and finish are excellent. The binoculars themselves are a revelation… the optics are surprisingly good, fit and finish very good, collimation was very good and even with my severe myopia I can focus the binoculars without wearing glasses and still have sharp star images. Astronomical images are great, the Double Cluster – superb, ditto the Pleiades (with nebulosity visible around Merope and the three other brightest stars). The moon was awesome… there is secondary colour as might be expected… I see bright lime green, sometimes magenta but this is only occasionally noted… at some viewing angles the secondary colour disappears completely, very impressive for non-apochromatic optics. The whole package weighs 32 pounds when set up, very light yet stable. Set up time is two minutes and you’re ready to observe. Airline travelling astronomers note: the binocs fit easily into a leather carry-on bag with plenty of room for T-shirts, underwear or socks to act as padding, the tripod and T-mount can go in a duffle bag… perfect for air travel to southern destinations. Only complaint: I inadvertently shattered the supplied 3/8-16 to 1/4-20 adapter when initially setting up the binoculars. Kevin B. responded IMMEDIATELY with replacement adapter… EXCELLENT customer service. Fantastic value for the money.

    I own 8×30 Swarovski SLC Mark II and Fujinon 10×50 FMT-SX, a very nice Parks 8″ f/7 mirror and have owned an AP 6″ f/12 SP refractor with TV 20 mm Nagler. All are great, but the biggest surprise of all is my delight with my new 25×100 Deluxe Oberwerk big binos fitted with TV dioptrix astigmatism correctors. I have a most elegant method of mounting these to the big binos without need of machining, but the space in this review doesn’t let me include it now…
    Thank you for these big binos at such a great price!
    ps. Lube’s a bit sticky at 10 below. 😉

    Just wanted to let you know my folks are really enjoying the binoculars we got them. They live on the north side of the big island of Hawaii and watch the whales migrate past from their bedroom.

    I have had these 25×100 IF, for a few months. These are great binos for the money! The FOV and the eye relief work very well for me! And the views – superb!

    I have the perfect setup for star parties (with my mount). Many of my astro imaging friends were impressed; one of them has taken more interest in binocular astronomy after looking through these 25×100’s.

    I have already recommended the Oberwerk 25×100 to a couple of people, who have considered a 25×100 giant bino. I myself would buy these binoculars again without hesitation.

    Thanks to the staff there for their wonderful customer service.

    I wanted to thank you for speaking with me by phone last week and assisting me in making my decision to purchase the 25×100 IF Deluxe binocular. It arrived at the end of last week and as luck would have it, I’ve had nothing but cloudy evenings until tonight. Thirty minutes ago, the clouds cleared for 20 minutes so I mounted the binocular on my parallelogram mount and started looking. I observed Jupiter and four moons. The view was pinpoint sharp and I could make out Jupiter’s bands. Needless to say, I’m amazed at the exceptional optical quality. And, I appreciate your quality control and that you checked out the binocular with the accompanying checklist prior to shipment. Thanks again for your recommendation and the beautiful optics!

    On March 21, 2017, I ordered luxury 25×100 IF binoculars with the Oberwerk 5000 tripod with head. Three days later my order was delivered. The quality of the product is impeccable both for the binoculars and for its extremely robust and versatile tripod.

    I would like to thank you for your excellent service and for the quality of your products.

    Just purchased the 25×100,and 5000 Tripod with upgraded head mount. Came packaged very well, no damage. The unit is very easy to set up and really nice looking. Item and components are really well built and easy to transport for various viewing areas. Binos are extremely sharp and clear and easy to adjust, I opted for the CF focusing. This is my entry in to this hobby and found Kevin and Linda with customer service more than knowledgeable and courteous in helping me with my purchasing choice. I had always wanted some Oberwerks and made a sound decision in purchasing this equipment over other brands. I felt a really great price for quality equipment and outstanding customer service. The company is terrific. Thank you all so much.

    Just got these giant binoculars. They are really impressive. I’ve never bought a pair of binos at that price and with a quality of lenses like that before. I am an astronomy amateur. It is needless to say that the Orion nebula and all other Messier objects seen through my 25×100 IF are amazing, Takes 2 minutes to get ready for observing instead of 30 minutes with my old telescope. I would recommend them anytime. Thanks Kevin for this excellent product.

    I’ve had this binocular for several years now. I live on the edge of mountains and love watching elk on the mountainside miles away. I am very impressed by the optical quality. I was only planning on using them for star watching as I felt the quality would not be good enough for land viewing. I actually have Swarovski 8x50B for that but boy was I wrong- these are wonderful optics.

    I purchased the set of 25x100IFs this spring. Had I known I’d be having so much fun this year with them, I’d have gotten them a LONG time ago!

    I use the RDF on the rail, even though it is generally not needed, it is nice to have. I use Baader MSG and polarizing filters for Solar System objects and twin Orion Skyglow filters for DSO hunting on occasion, when trying to see more in nebulae. All work very well with this pair!

    I use both Oberwerk tripods (one with the parallelogram mount and one standard with CF stem. the latter I use the Technosky eLLe mount with Skystuff 1″ threaded extension for mounting.

    These balance very well, fit and finish is excellent on my pair. VERY shapr views within at least 70% of field, mine starts to soften nearer 85%+. Very confortable and easy to use in both mounting configurations.

    I also use Baader solar filters with polarizers (on EP side for the latter) and the sun looks fantastic! TONS of granulation and faculae detail along with spots, although this year has been wanting for spot details.

    The lunar views with polarizers is breath-taking! I have caught th elunar south polar mountains coming into sunrise and saw several glints and brightening events in these. NICE!

    I rate these a 5 star pair for two reasons – excellent quality construciton and general performance and of course the FUN factor! Some minor chroma is observed on the birghtest obects but it is expected in an achromatic short f-ratio optic, but well manageable. Use of Baader MSG filters or Neodymium semi-apo units help this a lot.

    Oberwerk has been a joy to deal with over the years and I can say that without hesitation, any purchases from them are virtaully guaranteed to please!

    Keep up the great work Kevin!

    Extremely happy with my purchase of the center focus 25x100s. The quality of the optics is superb, with very sharp pinpoint stars across 80% of the view. The 4mm exit pupil darkens our already dark skies even more and makes hundreds of faint clusters, galaxies, and nebulae easy to find. The big bright objects like the double cluster, M31, M7, the beehive, and many others are truly impressive in these binoculars. A few nights ago I tried the ring nebula for the first time in these binos and there it was a perfect little doughnut in space. The polar cap and dark markings on Mars were easy to see and Saturn is very sharp although I could not make out surface details. The Helix nebula looks as good as it does in the 20” and the veil nebula has never looked better. I did have do a slight collimation adjustment when I got these binos but that was pretty easy once I found the right size screwdriver. No one else seemed to have a problem with them so I guess i am just extra sensitive to optics that are slightly out of collimation. I have been using these at our star parties and every one that looks through them has been impressed. So, after about 2 months I have to say that these are the best purchase I ever made for my astronomy hobby. I am using these on a bogen 3036 tripod and a 501HDV head, which seems to be a perfect match for binoculars this size. Thanks to the folks at oberwerk for selling these at a great price.

      Thanks Lane, happy to hear you are enjoying your Oberwerk 25×100! We ship perfectly-collimated binoculars, and despite our careful packing, occasionally things go wrong in shipping. We typically send a replacement with a prepaid return label, but glad you were able to correct this yourself- great job!
