    Default Celestron Barlow vs Televue Barlow Question



    Newbie here, my first post. I got a Celstron 5SE for Christmas. I was wondering if I would notice a difference in quality of image by upgrading my standard Celestron barlow with one from Televue?

    Welcome to the Forums.
    Unless you up-grade the eyepieces that came with the scope, you will probably not see much, if any difference at all. I takes a lot of observing time behind eyepieces to even begin to see subtle differences in them.
    Indeed the Televue barlow would still be a good investment as it would be a "Keeper" that will probably live through many telescope up-grades in the future, and you can be assured that it is in no way affecting the images projected by the eyepiece.

    Technically, the TeleVue Powermate is not a Barlow. It is definitely optically superior to the standard Barlow, but whether you will find the difference to be enough to justify the increased cost is something I cannot answer.

    cant answer this, celestron had different barlows old and new, same with televue, any upgrade would be somewhat better to a premium barlow, usually with a larger field stop

    Besides the Powermates, TV does sell regular barlows as well. Specifically a 2X and 3X 1.25 inch, plus the 2 inch Big Barlow 2x. As to whether the Celestron would compare well to those, I can't say, having not used any of them, and not owning a barlow at all.

    I have used a televue and also own a 2.5x luminous celestron Barlow . I don't see any difference between these two except price . Although that's a real amatures opinion . The luminous Barlow is celestrons premium Barlow though as well. I've heard some say the televue doesn't loose light haha but you can't defy the laws of physics

    I was wondering where the Televue Powermate came from? It was not mentioned until this post. I have a Televue barlow but that does not make me think anything about a powermate (whatever that is). Just curious. Thanks.

    Absolutely not! I've had barlows and rarely used them. I don't want another piece to fiddle with, and much prefer using stand along eyepieces to get what I want. Therefore, for myself, I don't have a need.

    The powermate was designed more for photography but can still be used as a regular barlow. A barlow multiplies the power and f/ratio but also increases the eye relief a bit. A powermate will not increase eyerelief and has a flatter field of view.
