Space20 Posted January 16 Share Posted January 16 I have a 4 inch refractor and I am considering buying a higher power eyepiece than the 10 mm I currently have. What eyepiece would you recommend? I am considering buying a 5mm, but I am concerned that the planetary views would be too blurry at 132×. Should I get the Agena starguider 8mm or 5mm? Or something else Quote Link to comment Share on other sites More sharing options...

Carbon Brush Posted January 17 Share Posted January 17 Knowing the model and focal length of the refractor will guide the recommendations. Do you observe with glasses? That also influences eyepiece type. Quote Link to comment Share on other sites More sharing options...

Nightspore Posted January 19 Share Posted January 19 Depends on the quality of the glass in the scope. FPL-f3 and you can push to 240x. Less around 120x is good. Quote Link to comment Share on other sites More sharing options...
Moonlit Posted January 19 Share Posted January 19 If you don't have a decent 2x Barlow lens, I'd get that. A 10mm with a 2x Barlow will give you the equivalent magnification of a 5mm without a Barlow. Quote Link to comment Share on other sites More sharing options...
