iOptron 10 mm & 25 mm Plossl Eyepiece Set - TP100


iOptron Plossl Eyepiece Set

This set of two Plossl eyepieces is an economical way to outfit a beginner's telescope. Each eyepiece has a 1.25" barrel, which is standard size, and will fit into a 1.25" diagonal or focuser. Plossls tend to have a medium field of view. Both of these eyepieces have a 50° apparent field of view.

The 25 mm Plossl eyepiece, which has a comfortable 17.5 mm of eye relief, provides lower power, wider field views. Use this eyepiece to find the object you are looking for, then center it in the field of view before changing to the higher power (10 mm) eyepiece. The iOptron 10 mm Plossl Eyepiece, with 7 mm of eye relief, provides higher magnifications, the exact number is dependent on the telescope it is used with.

Add a 2X Barlow to your accessory case (sold separately) for a great way to get more out of your 25 mm & 10 mm eyepieces, as a Barlow lens will double the magnification of any eyepiece you insert into its barrel. A 25 mm, for instance, will magnify the image like a 12.5 mm eyepiece would, and a 10 mm will perform like a 5 mm (very high power) eyepiece.
