How to Choose a Proper Telescope Eye Piece?

Go to telescope.com

They have excellent tutorials and great (human) customer service that would help you. The short answer is that "NO", you don't have to have that size eyepieces. The longer the eyepiece, the less magnification. ANY 1.25" eyepiece will fit.

best of luck

There are two standard sizes, 2 inch, and 1 1/4 inch. You have the latter. Any 1 1/4 inch will work with your scope. The other number is related to the power (magnification. The SMALLER that number is, the higher the power. A lower number gives you less magnification, and a wider field (like binoculars). A high power eyepiece gives you a narrow field of view. This can be like trying to look through a drinking straw if you put a very high powered eyepiece on a very small scope. Another good lens to own is a Barlow lens. You put thin in the eyepiece holder, then put the eyepiece in the Barlow. It doubles or triples the power of whatever eyepiece you put in it. It's like getting two for one! Ill send you some links.

You can always find something cheaper on the internet. What you don't know is whether it will arrive after you pay. These are reputable sources.

A 9mm and 25 mm (approximately) eyepieces will give you a low power and medium power view.

A shorty 2x Barlow lens will double each power giving you four different views. Dont use over 100 power on this little scope or views will get fuzzy. It is a goto scope so practice setting it up in daylight a few times and you won't have the frustration that ofen goes with using a telescope.

Here is a good ebay company to buy high quality eyepieces:

This would be a good one for your ~9mm eyepiece.

Finally, you need to know eyepieces come in 3 sizes. Your telescope needs 1.25 inch eyepieces. This is the outside size of the barrel that slips into the telescope eyepiece holder.

Have fun and learn alot from your telescope.

Hey, i have the same telescope u r having i have 2 eyepieces 1 is the 25 mm its perfect to see moon & other plantes but these objects will look smaller.

i also have the 9mm eyepiece which can be used to see more further objects but its fiels of view is narrower than the 25

i also have a barlow lense it can be fitted with eyepiece and it will double its power so for the best view i use the 25mm + the barlow lense together.

congratulaions for new telescope & clear skies.

Two things could be going on: 1) Because of its short focal length, a 6.3 mm eyepiece has a very tiny field of view, so the object you were looking at with the longer focal length eyepiece may no longer be within the much narrower field of the 6.3 mm. I generally sneak up on objects by using several eyepieces, rather than switching straight from low to high power. Did your scope come with a 10 mm eyepiece? Use that in between the 25 mm and the 6.3 mm. If you don't have a 10 mm eyepiece, consider getting a 12.5 mm eyepiece, which is exactly half way between 6.3 mm and 25 mm. Sirius Plössls are OK, but you'll get a much better view if you spend a bit more on better eyepieces. Orion Stratus eyepieces are really nice. 2) This eyepiece may need extensive refocusing compared to your other eyepieces. If it's badly out of focus, you won't see anything, unless you're looking at something really bright, like the Moon. Experiment in daylight to learn how far you must turn the focuser wheel when switching eyepieces.
