## Description

BARSKA's Encounter "Jumbo" observation binoculars are incomparable optical instruments that are perfect for long-range terrestrial viewing and celestial viewing.

Tripod adaptable fittings for both side and bottom mounting. When not in use, the Encounter Jumbo can be stored in the included deluxe rigid foam-lined carrying case.

Review: Just got these today overnighted by Barska on a 5 month payment plan which is great timing! My first thought upon writing a review here is that Barska is not messing around! Perfect condition. Cleanest optics I've ever seen in ten years of buying. Are these a new version? Must make them in a cleanroom. I've heard stories about nortorious collimation problems, eyepieces not interchangeable, eyepieces not coming to focus... all in the past now. Super build, ultra fine focus, high quality case that the others out there don't come with. What a great night with these living near a white zone. Can't wait to get these to Yosemite next week! Got my rigel finder attached. A must have. First off, these provide a correct view of the sky. A must! The reason why they say you cannot see a view in anything else like these is because even though the field of view is very wide and pulled back from the target, the light grasp of two large lenses lets you see fainter stars. So everything in view has so much resolution! and contrast! The correct image view cannot be had in a telescope with diagonal without spending lots of $ on a correct image prism. These big binos already have correct image. Another savings. Truly incredible views. On axis views on bright obects do show a bit of color (CA) as to be expected as a semi design and polish. Extremely subtle! - almost gone in excellent seeing I'm sure to find. I did not purchase these to look at bright planets or the moon. Or the brightest stars. These are for expansive views of deep sky objects in a way that only these can do. Add third party 3D eyepieces and the true value in these becomes instantly clear. Plus I've come up with a way to mount these nicely balanced on a Tele Vue Tele Pod mount / Manfrotto tripod = near light gathering of a 140mm semi-apo, push-to Go To Sky Tour, 3D astronomy, correct image - seeing obect as it really is, easy travel to real sky or better yet Southern skies, and can carry it all with one hand. My most joyous grab and go set up to date. Well done. Edit: couldn't get to Yosemite. Was in a blue green zone down south. M22 (globular cluster) in 3D was worth the purchase. A life affirming evening with these. Spectacular wide field views. Edit 4/2021 Perfect seeing won't remove CA on any brighter object. M13 was a sight to see the other week. My new favorite star field goes to Altarf incredible. 10/2021 Add BinoBox solar filter found on Binohandle. com
Review: 普通の双眼鏡と比べると・桁違いの迫力が味わえます。双眼鏡の素晴らしさ・楽しさをあらためて実感しました。アイピースがいろいろ取り付けられるのでこれから楽しみです。アイピースを揃えその気になれば500m先のネズミまで捕えます。映像もすばらしくシラサギの表情・緊迫感まで伝わってきそうです。大きな三脚が必要で・私はマンフロット504ＨＤ・アルミを使いましたが装着に少し難儀しました。アイピース7ｍｍクラスで覗くと迫力の月観察が見れます。眼疲れが少ないのも良い点である。

*by C***1 on 10 February 2016*

This is exactly what I wanted when I ordered these. I live in Maui and got these for watching whales off of my lanai Great resolution the 40 X Power is great for Viewing whales 10 miles or more away when I look over the ocean with my naked eye I see nothing, I looked through the Barska jumbo it is whale soup everybody has been extremely impressed with the quality of the viewing experience my wife even enjoys using these throughout the day. You definitely want to have these on a tripod focusing each side separately is a little challenging however the result is excellent The images are bright and crisp with great detail.
