New Telescope Eyepieces Will Improve Even The Finest Telescopes
Should I Change My Eyepiece? Now that you have bought or perhaps have been given a new telescope, you're thinking about making it even better. One the first things new telescope owners usually replace are the telescope eyepieces.
Many people, especially beginners, have a tendency to want to overdo it when it comes to upgrading their telescope eyepieces. You might want to learn a little bit about telescope eyepieces before you spend more money than you really need to.
Astronomy buffs are no different from other enthusiasts when it comes to their hobby or in some cases passion. It is very natural to want bigger and better. At some point in time you will probably want to upgrade your telescope to a larger aperture model. However, a good alternative to spending more money than necessary is to check out new eyepieces instead. There are many quality telescope eyepieces out there that will make your current telescope feel like and perform like a new telescope.
The proper telescope eyepieces will have a positive effect on the brightness of images, and will also improve magnification and the field of view. The changes in the views that you receive can be remarkable with the right eyepieces.
Know What to Expect from Your Eyepieces
Good telescope eyepieces need to have features that will work in conjunction with your telescopes optics yet enhance and improve its performance enough to justify the added expense.
You should look at telescope eyepieces that will work best for the majority of users and also the majority of telescopes. Most newcomers to astronomy will be literally blown away by the difference in viewing experiences of quality telescope eyepieces compared to the eyepiece that came with their telescope.
Simply put, the answer to the original question about upgrading your eyepiece is yes. However, it is always good to do a little research and have some helpful tips beforehand.
Telescope Eyepiece Buying Tips
Consider the following advice when buying:
Eye Relief
Eye relief is a term you should become familiar with. It is the amount of distance from your eye to the point in the eyepiece where the images are formed. The longer the eye relief, the more comfort in viewing. If you wear eyeglasses, try to get telescope eyepieces with an eye relief of 15 millimeters. A better eyepiece will allow for some adjustment in the eye relief, where the less expensive ones are fixed. So, if you do wear glasses the eye relief is important. Even if you do not wear glasses, you will need enough eye relief to insure that your eyelashes don't touch the lens. Oils transferred from your eyelashes can cause damage to the lens coatings. So, clean your telescope eyepieces often.
The View - Eyepiece Size and Diagonal
What you see when you look into your telescope eyepieces is largely determined by its size and the size of the diagonal. A diagonal is basically a prism or mirror combined with a reflector. The image is reflected from the main lens to the eyepiece via the diagonal. The eyepiece fits into the diagonal which is mounted on the side or top of the telescope. The diagonal is an important factor when it comes to focusing the eyepiece
The industry standard for diagonals on most telescopes that you initially purhcase is an inch and a quarter. As you insert different inch and a quarter eyepieces into different size focal lengths, you will receive different magnifications, and you can easily control the focus at the telescope.
Another option, which works well when you have a long focal length on your telescope, is to add a two-inch diagonal. It helps with deep sky viewing by bringing in those dim and fuzzy objects more clearly. There is quite a difference when viewing with a two-inch eyepiece, and could be compared to looking out of the window of the space shuttle. With two-inch eyepieces you can actually look down, right, left and all around which is very much like having your own window to space.
A two-inch eyepiece is designed for low power and a wide FOV (field of View) which keeps your image view bright and sharp from one edge to the other. You can still use your two inch diagonal with one and a quarter eyepiece by adding an adapter. This is a good option when you need high power to view planets and the moon, but do not want change the diagonal.
Buy Your Telescope Eyepiece Wisely
Buying telescope eyepieces can be somewhat expensive, but less expensive than a new telescope, so look for reputable manufacturers that offer money back guarantees and good support. Buying online is a good approach. There are a lot more choices in one place and the sellers tend to be quite reputable. It is also easier to find more eyepiece vendors online than at your local shopping mall.
