Окулярът Levenhuk Zoom е окуляр с вариращо фокусно разстояние, който може напълно да замени няколко окуляра. Вие можете лесно да намерите обект за наблюдение с малко фокусно разстояние и след това да го изучавате с максимално увеличение. Въртящата се гумена чашка позволява удобни наблюдения със или без очила. Всичко това прави този окуляр задължителен за всеки запален астроном.

Скалата, отбелязана на корпуса, Ви позволява лесно да настроите желаното фокусно разстояние в диапазона 7–21 mm и ще имате гарантиран кристалноясен образ при всяко фокусно разстояние. Всички оптични елементи са изработени от стъкло.

Окулярът има Т-резба под чашката (M38x0,75), която позволява да свързвате SLR камера, като използвате Т-ринг (не е включен в комплекта). Забележете, че за да свържете Т-ринг, трябва да премахнете гумената чашка.

Hello! I own Sony Alpha 77 camera and Levenhuk Strike 1000 Pro telescope. I can attach the camera with a T-ring to the telescope, but I won't achieve the highest practical power of the instrument.

Levenhuk Zoom 7-21 Eyepiece is used separately from the camera. You can either install the eyepiece or t-ring with camera.

Karl WILDER (2013-12-03 05:02): Положително
Hello! Would you mind telling me if Levenhuk Zoom 7-21 mm Eyepiece is so-called "wide-angle"?? If not... is it reasonable to buy wide angle (as far as I get it) Levenhuk Zoom 8-24 mm eyepiece for my Levenhuk Skyline PRO 90 MAK? Will the last one allow me to get 125-180x magnification? While keeping the image sharp? Thank you in advance! Levenhuk Обслужване на клиенти:
Levenhuk Zoom 7-21 mm Eyepiece indeed provides field of view of up to 30% less than the Levenhuk Zoom 8-24 mm eyepiece. To obtain the highest practical power while keeping the same image quality you will be needing an eyepiece with 7 mm focal length; with Levenhuk Zoom 8-24 mm eyepiece you will get 156x increase, that is quite enough for planetary observations.

Chris Ballow (2013-09-30 09:50): Положително
One more question from the space nerd: is Celestron X-Cel 2.3 mm, 1.25" suitable for my telescope? I've got no time to read "the alphabet", it's easier to type the question on the tablet. Thanks. Your info is the most intelligible! Levenhuk Обслужване на клиенти:
Thank you for your comment. Unfortunately, this eyepiece doesn't fit. The highest practical power will be exceeded. Try Levenhuk Ra LER 5 mm Eyepiece: https://www.levenhuk.com/products/eyepiece-levenhuk-ra-ler-5/

Chris Ballow (2013-09-30 09:37): Положително
Is this 7-21 eyepiece suitable for my Levenhuk strike 80? What's the difference between the same eyepiece ( only 8-24)? Why the price is twice higher? And also how does 5x short-focal-length barlow lens work on my telescope? I observe planets, the moon, mars so on. Levenhuk Обслужване на клиенти:
It is suitable for Levenhuk Strike 80 NG. The difference is the focal length. There are many factors affecting the price such as the date of procurement, rate of currency at the moment, etc.

Joe Butler (2013-08-28 03:43): Положително
So I have Celestron LCM 114, can I use this eyepiece together with Levenhuk 2x Barlow lens? (except for 7 mm value obv) Levenhuk Обслужване на клиенти:

Tom Sorenson (2013-08-15 09:59): Положително
Please tell me what image quality does the combination of this eyepiece and 3*BL Celestron NexStar 130 SLT provide? So by attaching on 7 mm I get the magnification of 280. what'll be the quality if this telescope claims 306? What focal length can I install after 7mm (what is the step?) Levenhuk Обслужване на клиенти:
The highest practical power is calculated by formula D*2, where D is the objective lens diameter. It's 260x for Celestron NexStar 130 SLT. If you exceed this point the quality of the image will be reduced. Levenhuk Zoom 7-21 mm eyepiece has the following focal lengths: 7, 9, 11, 15, 21 mm.

Molly Eisenhauer (2013-08-06 12:31): Положително
