    Default EP recommendation for 6" F/5 Newt



    I've just purchased an Orion Starblast 6, and I'm seeking advice as to which eyepieces I should pick up to augment the 25 & 10 mm Plossls that the scope shipped with.

    I wear eye glasses, and therefore require an eyepiece with generous eye relief. I 'm considering the Orion Expanse 6 mm wide field, or the 5 & 6 mm Orion Edge-On planetary EPs.

    Any thoughts?

    I have a 6mm expanse clone for my f/5 5 inch reflector. Works fairly well. The TMB planetaries in the 8-4mm range will be sharper(I have the 5mm). If your looking for longer focal length EP's that don't have too many optical issues from the center of view, I'd recommend the Astro-tech Paradigms. I own the 25mm and 18mm. If you go cheap widefields, expect lots of coma and astigmatism(stars look like comets, seagulls, or just out of focus) away from center. For a little more money, the Meade 5000 UWA are probably better in regards to edge correction.

    When this question comes up, I always steer the questioner to the discussion of Zooms at the top of the Eyepieces forum.
