    Default barlow vs. new lens?



    is a 23 mm lens with a 2x borlow the same, better, or worse than a 12 mm lense in quality and vission?

    depends on your personal take.
    some people prefer the 12mm/12.5mm ep,
    as there is less glass in the light train.
    but others prefer the barlow method,as you retain
    the better eye relief with th 23mm ep,but the power
    of a 12.5mm.
    the quality of barlow will also come into it aswell,sometimes.

    ive only used one barlow ( tal x2) russian made. it's rated well amongst the budget range. i was troubled by the eye placement,had to be quite accurate or youd get black out.
    so now ive got a 12mm 60 degree fov e/p. and i prefer it hands down.

    but ive read many a thread about barlows, and it is most certainly a personal thing.

    I think barlows are nice for eye relief for focal lengths shorter than around 8 mm. For 9mm and larger focal lengths, to me the barlow isn't worth the hassle.

    If you are "relatively" new to the hobby I say get the barlow ... BUT only because it almost (or can) doubles your current eyepiece collection...

    As the years pass you most likely will discover that your eyepiece collection has grown and you no longer find any need for a barlow...
