True or False: Clearing the Telescope Eyepiece Puzzle

 Telescope Eyepiece Q&A


Thanks for visiting this brief article of a number of the questions and their solutions that we receive coming from men and women who wish to grow to be a specialist in the Telescope Eyepiece. Today we are going to be reviewing three important inquiries that we get, with regards to... Power, the issue of wearing Glasses at a telescope and also the importance of the Barrel Diameter of a telescope eyepiece. Once you have read this content you are going to know a few of our thoughts about the power of a Telescope Eyepiece and how to receive the best view through your telescope whilst using glasses. We will also be exploring the distinction between Barrel Diameter and Field of View of a Telescope Eyepiece

Q: True or False? Power is the main aspect when buying a telescope eyepiece.

A: False. All optical telescopes have got practical limits with regards to delivering a picture. The telescope eyepiece enlarges that picture so that the operator may view it clearly. Using an eyepiece with a greater magnification may well produce a bigger picture, however that view will also be dim compared with that produced by the lesser powered telescope eyepiece. The picture may be much more hazy and much less distinctive.

Q: True or False? It is difficult for a person to look through the telescope eyepiece if wearing spectacles.

A: True. It is sometimes complicated for your eyeglass user to see through the higher powered telescope eyepiece, since they cannot get their eye close enough to the lens. Though, frequently it is not so much of a difficulty for the eyepieces with a low magnification.

But, telescope eyepieces of good quality can have their “Eye Relief” stated on them. “Eye Relief” is the way of measuring how far a person's eye needs to be from the telescope eyepiece in order for a person to be able to perfectly view the image.

Those eyepieces with an “Eye Relief” about 20 mm are typically satisfactory for most people who use their eyeglasses with a telescope.

Q: True or False? Barrel Diameter establishes what amount of the sky you can see.

A: False. Barrel Diameter of the Telescope Eyepiece is a measure of the physical dimension of the eyepiece that fits into the telescope's eyepiece holder.

It is the Actual Field of View that establishes how much of the sky you can see, indicated as an angle, and often somewhere between one tenth of a degree and two degrees.

This isn't to be confused with the Apparent Field of View, which is an angular measurement of the picture observed in the telescope eyepiece (as distinct from magnification). Apparent Field of View normally varies from around 35 degrees to around 80 degrees

One of the most convenient method of establishing the Actual Field of View can be calculated if you know the Apparent Field of View.
