    Default High Power Eyepieces



    Since I recently got a new reflector telescope, and my first, I spent some time researching telescopes beforehand to make sure what I wanted. It's something that I do with everything if I want to get a feel for it. Basically, my Orion came with two 1.25" eyepieces, a 25mm and a 10mm. From my old refractor, I have a 25mm and a 9mm, with a Barlow lens too.

    Since the highest useful magnification on my particular scope is 260x, I would either need a 5mm (Because of my Barlow) or a 2.5mm. Would this work for me?

    Hi ROS,

    Have you considered that Barlowing your 10mm gives you 5mm? Your 9mm will give you 4.5. Maybe on Kilhuea or up in the Andes will give you conditions which will allow use of a 2.5, but it's unlikely anywhere else...

    Clear skies...

    I do know that Barlowing my current eyepieces gives me a higher power, and am also aware that it sacrifices some light in the process. The reason I want a 5mm, though, is so that I can Barlow it to get 2.5mm, or a 2.5mm so I can use it on its own.

    You will rarely be able to use that much magnification anyway. People need to realize that just because these telescopes list a theoretical number for magnification, doesn't mean that the atmospheric conditions will let you use that much mag more than once or twice a year.

    I'll say nothing will give you a better view than a low power ep, I use zooms and fixed high power for examining details of planets, moon , gases and stars . If that's what you want to do get a fixed ep, for the better view or dig deep and get a premium ep{ Nagler.}
