    Default Which is better for DSO's a refractor or a catadioptric?



    Which is better for viewing DSO's, a refractor or a catadioptric (say a SCT) of the same price? I'm thinking the answer must be the SCT, but am not sure.
    The comparison might be between a 6" SCT and a 4" refractor ( I think they are about the same price) .

    You've really not given us enough information to go on.

    Purely speaking optics, I would take a 4 inch triplet apochromatic refractor for most purposes over the 6 inch SCT.

    But at the price point of a 6 inch SCT you are probably talking about a decent 4 inch achromatic refractor - and personally I'd go for the 6 inch SCT in that case.

    Nice 8" cat on an equitorial or fork $2000.00 or less new. 4" apro on same as capable with as little chromatic $2300 and way up.

    Ole Cuss brings up a valid point.

    Optics is obviously very important when considering a telescope.

    I would urge you to also review ALL your options of telescopes before jumping on these two.

    Best of luck with your decision none the less.

    I agree with Alex, I would expand your search. Dobs are great for DSO's and should also be a part of your search. Good Luck.
