    Default Which Barlow?



    Hi everyone,
    I have a SW 6" dob, 1200mm. I am looking for a barlow and I would like some opinions on the following ones:

    Sky Watcher x2 1.25" Deluxe Barlow: Amazon.co.uk: Camera & Photo

    http://www.amazon.co.uk/Celestron-93...d_sim_sbs_ph_1

    Celestron X-Cel LX 1.25 inch 2x Barlow Lens: Amazon.co.uk: Electronics

    TeleVue 2x Barlow 1.25": Amazon.co.uk: Electronics

    I know that the last two are excellent barlows, but are the first two that bad? The price difference is quite big. Is it really worth it? Got any other barlows to suggest?

    Clear skies!

    I have an Orion 2x and it works great. But I have been thinking of getting the celestron x-cel for my next scope. I am new to this to so maybe wait for a couple more replies

    I've got the Celestron Omni 1 1/4 and it does the job but, it's made mostly of plastic so taking it apart to get to the lenses for easier cleaning is not happening. I've also got a Zhumell 2"2x ed barlow that is sweet, comes apart and is made of metal,breaks down for cleaning and I've got a 3x Celestron barlow made of plastic. I think the plastic casings are super light for equatorial mounted scopes like my powerseeker , your oculars make your scope what it is. It's a fact that faster the scope the pricier the occulars , you like the 2" oculars like my Z10 . I've got a Celestron eq80 powerseeker and the eyepieces that came with it gives off false colors on planets, It's a f/11 refractor slow scope and cheap oculars do that, my other plossl oculars work well with it.

    To be honest there is NOT much difference between any named brand 2x Barlows...I've owed dozens of them over the years (I'm 70 and have been in this hobby since I was a cub (not boy) scout....I currently use a Denkmeier S1 P/S 2" diagonal that has a build in 2x barlow along with a Focal reducer in both my Scts...BUT I carry a Televue 2x in my case I use with either of my refractors I use at star parties...

    The Televue I got as part of a purchase on a used scope otherwise I would never have purchased it because it while good ..it is not really any better then most of the ones I have used over all these years... The only reason I kept it was that it had those green letters ...

    As long as the darn thing is not plastic and is made by a brand named company who is not bashful about plastering their name a product I would not worry which one I purchased......

    Now I do NOT have any interest at all in AP so I can't say anything about true color transmission when using a camera. instead of my own eyeballs...

    Pick a mid priced named brand barlow and you will be satisfied ...

    TILLIBOBS and Pitter like this.
    CPC1100 housed in a slotted domed observatory (Exploradome) 4 and 5 inch refractors for use from the lawn, a 8" Sct (NS 8i) for star parties...

    agree with Bob327 but i like the Big 2X Televue because it accepts the 1.25 and 2 inch EPs

    I've found a used Televue. I'll take a look at it tomorrow. What should I watch out for? (i don't think i'll be able to test it on a scope)

    If you are looking at 1.25" Barlow's I can tell you what is better and that is the Televue 2.5 Powermate. Not cheap but in my opinion they are worth it.

    Got the Televue! Tested it tonight at Saturn. The seeing was awful+lots of light pollution. 38*C with lots pf humidity-didn't even bother going to the roof, I just gazed from my balcony. Used it along with the 10mm EP that came with the scope (SW 6" dob, 1200mm). So, that's sth like 240x-really stressing my scope. But still...it does the trick. A tiny bit blurry and a little less bright, but still...I wonder what it can do in better conditions. Maybe coupled with a good 15mm EP!

    You really need reasonably good conditions to use a Barlow, otherwise you will be magnifying the bad atmosphere.

    I have the Celestron one and am totally happy with it. Been using it mainly with my Hyperion Zoom EP.
