The Oberwerk 25x100 Deluxe IF Binoculars for Astronomyfrom Oberwerk 25x100 Deluxe IF Binoculars for Astronomyoffer both-eyes-open astronomy as well as terrestrial glassing, with the power of high magnification and large objective lenses. Between full antireflection broadband multicoating and BAK4 Porro prisms, you can expect crisp, high-contrast, true-color images. Floating mount plates help the prisms stay aligned despite jostling in the field, an improvement over common prism-mounting methods. The 18.5" optical tubes are waterproof and nitrogen-filled for fog resistance. The chassis is wrapped in nonslip rubber armoring and has an integrated tripod mount.

Related Questions and Answers

Q: 1. why does it say aluminium housing on the celestron website.....is the above a mistake Each Echelon binocular housing is made of aluminum alloy, to keep them strong yet lightweight, an important factor when considering a big binocular purchase.Reply Vik S on Mar 23, 2015 ?

A: Yes this binoculars housing is made out of Aluminum Alloy. My apologies for the confusion on the site. I will alert my Web Team to update this.

Q: 2. dose it come with BAK 4 glass ?

A: The Vortex 8x26 Vanquish Binoculars do feature BAK 4 glass.

Q: 3. Are the optics on this binocular glass or plastic?

A: Great binoculars, feels like glass, but not sure. You'd be better googling it or asking the supplier sorry.

Q: 4. Do you have solar filters available for the 25 x 100 binocular

A: The MrStarGuy Adjustable Objective White Light Solar Filter (86-117mm OD) might work well. However no guarantee. These really weren't made to accept Filters. You would need to purchase 2 pieces. Website link: https://bhpho.to/2iDa5RJ

Q: 5. Are these binoculars waterproof?

A: No. They are not waterproof or fog-proof.

Q: 6. I have a Celestron 25x100 binocular that came with a Celestron Alt-Azimuth tripod Model 93607 but they don't seem to mate very well and the tripod does not elevate more than a few degrees above hrozontal. Do I have the wrong tripod?

A: I have the same binoculars and tripod. The mating to the tripod is very solid; no problem at all. Perhaps you've sorted that out by now. The range of elevation angles is somewhat limited from what I'd prefer. It's about plus/minus 20 degrees. However, anything more could make it very awkward to sight through the binoculars.

Q: 7. Do these have the lifetime warranty from Nikon?

A: Yes, this would come with a Limited Lifetime Warranty from the manufacturer.

Q: 8. If out-of-collimation, is it possible for the user to adjust the collimation?

A: Collimation of the Celestron 25x100 SkyMaster Binoculars BH #CE25X100SM • MFR #71017 cannot be done by the consumer.

Q: 9. is the Skymaster binocular kit new?

A: Yes, the Celestron 25x100 SkyMaster Binoculars Kit is new and includes the original warranties and accessories shipped from the manufacturer.

Q: 10. Need to buy a Nikon Travelite case only. Lost mine. Are they available?

A: Im sorry the Travelite cases are no longer available.

[Porro (BAK4)] When I got these, packed in two, not one, cases, I immediately set them up, with some difficulty, on the excellent Magnus VT-350 tripod that was quite properly recommended by the agent on the phone. Looking at a distant lightpole in front of a bright sky, I was struck by not only by the clarity of the detail (IF is great!), but also by the disparity of chromatic aberration. I planned on taking them out to the next scheduled star party with my Astronomical Society, to wow them a bit perhaps, but luck would have it, we were clouded out. Anyway, I would not hesitate to persuade anyone to save big bucks by going ahead with these first and in the unlikely event you are not blown away, then empty your wallet for a more munificent product. Going that far is not something I readily do, but there you have it! Clear skies and good luck for all of us seemingly cornered into this niche of observational obsessing... 5

[4 mm] Best price in the market for the Celestron 25 X 100 Binocular. Came well packaged, fast shipping and no damage. 5

Dan	02/08/2024
[4 mm] just runs on one battery, but still a nice bright red and also a lower light setting as well. I like how I can hang it from my neck. 5

[Individual] A mi papá le encantó (fue su regalo de cumpleaños) y a nosotras también. Se puede ver a larga distancia muy claro y enfocado; excelente! My dad loved it (it was his birthday present) and we did too. It can be seen from a long distance very clear and focused; Excellent! 5

[100 mm] it's an amazing product , it really brings things closer, 5

Slobodan	05/07/2024
[Individual] I was intrigued by the (1) optical array and (2) whether the 3-D effect was real. I live in Chicago but observe out over the lake. The array is not visible when observing the night sky over the dark lake and is only barely visible- and not intrusive- when turning away and observing over the city streets. The 3-D effect is subtle, but real. And delightful. Optics are excellent edge to edge with outstanding color transmission. It's lightweight and solidly built. For sheer enjoyment of the night sky, I recommend it highly. 5

[25x] All the talk about loose screws and poor construction quality are lost on me. These are very nice and powerful and clear - definitely worth the money. And you can't beat the warrantee. I use them for all kinds of leisure...very often it is hard to find what your looking at when you take your eyes away and see with normal vision. These are stronger than the 'cheap' bushnell telescope I've had laying around.....Definitely a solid product. Use a good tripod (10lbs for binoculars) and common sense with the mount and you'll do fine. Night viewing is also great...seems to let a lot of light in... 5
