    Default Can I get a review on x2 Barlow 2" for 8" Dob



    What do people use a x2 Barlow 2" for? I have a 2" 28mm eyepiece and from what I can tell it is used for deep sky views, what effect would a x2 Barlow have on the 28mm and or what do people use the 2" Barlow for in regards to said eyepiece? It seems to me that it would be more useful just to Barlow a smaller eyepiece.

    If you don't have a 14mm eyepiece, the 28mm + barlow will do the same job. Mostly, people use them for more magnification, but they are also useful for filling in gaps in your eyepiece collection without buying new glass.

    With proper selection of your EPs, a 2X barlow can double your avaliable set of magnifications.

    I have a 2" 28mm eyepiece and from what I can tell it is used for deep sky views, what effect would a x2 Barlow have on the 28mm and or what do people use the 2" Barlow for in regards to said eyepiece? It seems to me that it would be more useful just to Barlow a smaller eyepiece.
    Eyepieces with greater magnification generally have less eye relief. So, placing a barlow in front of a longer EP gives you the magnification you want with the eye relief you want--and does so at low cost.
