As I mentioned earlier in the article, not all Plossls are created equal, which simply means that there are good Plossls and then there are bad Plossls. These lenses are connected together. For shorter focal lengths, the StarGuider BST series eyepieces have greater eye-relief, so are better suited. Note to spectacle wearers: Plossl eyepieces with 15mm and longer focal lengths are good choices for spectacle wearers but for shorter focal lengths the Celestron XCel LX series have greater eye-relief so are better suited. Is there anyway you could include links to the eyepieces you mentioned in the last paragraph of your reply as Im totally new so worried about buying the wrong thing! Lets take a look.

This means you will be able to see a greater expanse for the objects in space but with fewer magnification levels than Kellner or Plossl lenses. Non-eyeglass wearers can usually tolerate Plossls as short as about 10-12mm before their eyelashes start brushing the ocular lens. A Kellner eyepiece has 3 lenses, while a Plossl has 4.

Using this approach, you would buy a 2X Barlow and hold off on the 4 mm and 3 mm to see if you can reach these magnifications often enough to justify buying an eyepiece.

Higher values are slower and lower values are fasterthis is a holdover from camera lens terminology and has to do with exposure times.). A 15mm Plssl might be worth it, if you dont wear glasses. I need some eyepieces with long FL for low magnifications. If you were considering a Meade Super Plossl, in that case just get the regular one also by Meade.
