Are Explore Scientific eyepieces good?
The Explore Scientific 82º eyepieces are excellent and well worth the price because: They provide a much wider field of view than the standard Plossl. They provide more eye relief, making them more comfortable to use, as well as more suited for people with glasses.
What is the function of the eyepiece?
Eyepieces (Oculars) The eyepiece, or ocular lens, is the part of the microscope that magnifies the image produced by the microscope’s objective so that it can be seen by the human eye. In this resource we will look at the different types of eyepieces, their components, how they work, and how to use them.
Which is better explore scientific or scientific eyepiece?
Both Explore Scientific eyepieces provide sharp, high contrast views with pinpoint stars throughout the FOV. The same was true with the 9mm Nagler and the 13mm Ethos. The views through all four were superior the 15mm Plössl, where the stars were not as sharp near the edges.
How is the field of view of an eyepiece calculated?
The true field of view of an eyepiece is calculated by dividing the apparent field of view, in this case 68° or 82°, by the effective magnification. In ends up both Explore Scientific eyepieces provide the same true FOV.
Is the Explore Scientific eyepiece the same FOV?
In ends up both Explore Scientific eyepieces provide the same true FOV. The true FOV for 1000mm focal length telescope is 1.1° (82 ÷ 71.4 or 68 ÷ 62.5). So I expected to see the same view when interchanging them in the focuser, with the exception of the field being more spread out in the 82° eyepiece.
Which is larger the 68° or 82° eyepiece?
Image 2 – This view shows the wide diameter lenses comprising both eyepieces. The 16mm 68° eyepiece is 62mm tall, 43mm wide and weighs 158g (5.5 oz.). The eye relief is around 12mm with a field stop diameter of 18mm. Although the focal length is smaller, the 14mm 82° eyepiece is the larger of the two.
