    Default Baader Zoom filter selection



    Hello out there, going to be purchasing a Baader Hyperion Zoom, hopefully very soon, and want to purchase a UHC filter. Its going to be used in a 10in dob most likely and I just wonder if I should spend the extra $25-30 to order the 2" filter over the 1.25" Will there be any advantage in viewing and has anyone used the Baader filters with other EP brands? Seems like Orion EPs are hit and miss with the threads lining up. Thanks for your time! Tony

    Hello Hakksaw,

    the Baader filters are tooled with a high precission, they should match with all 1.25" or 2" EPs.

    The Hyperion zoom has a 1.25" thread. With a 10" DOB, you'll possibly go for the wide field EPs, that are thraeded for the 2" filters. Ac the filters are expensive anyway, I'd look for a 2" filter straight on.

    Your focuser is most probably 2". You may screw-in the 2" filter into the focuser, and put on it the 2"-to-1.25" conversion tube to match the assembly to the Baader zoom.

    The good 2" filters are dirty expensive - they may cost more than the good 2" EPs.

    No advantage-- if you must buy a filter the 1.25 inch size will work-- (somewhat).

    Don't expect miracles-- nothing beats a dark sky for being able to see dim objects. The one filter should be an ultra high contrast filter-- you should also buy a moon filter(they are very low cost).

    That has been the experience I've had as well. Also, I'd be a bit careful with the Orion moon filters. I bought one last year, and I couldn't get it to thread into anything. I didn't find out about the threads until it was too late to return it to the seller and wound up having to swap out the glass with the metal rings of a used filter I bought for $2 (got lucky on that one).

    I have seen quite a few positive reviews on the Meade zoom, certainly seems to be a strong performer especially considering the price difference! I haven't had the chance to compare views unfortunately. May look into it a lil more! I have also found a few more unhappy folks with those orion thread issues while browsing too. Thats a bummer. Hate to purchase a couple just to find out they gotta go right back. Thanks for the input fellas! Tony

    Baader Hyp Zoom vs Meade

    Baader is working well in the mid range. At 24mm you'll have the tunnel view, at 8mm there is some contrast loss. That one from Meade will not differ too much. Baader may outperform the other 8-24mm zooms with the mechanical tooling precission (typical Baader), and with the 'phantom' coatings.

    Another story is the TeleVue Nagler Zoom 3-6mm, performing a crisp view in the full range. The drawback is the short eye relief.
    When it should be about a zoom, this one would be that 'must to have'.

    JG i put me hand on a TV zoom..looks ugly/weird...different. the store manager point out the first visible downside: eye relief...the small opening where you put your eye is about 5-7 mm on TV comparing with almost 2 cm on Baader or Meade. i set me eyes on a Baader Hyperion 5mm with tunning rings...that give me an all in all zoom: with 14,28 and combined rings i have 3 different EP. and it can be connected to DSLR...cool
