    Default lunt 80mm ED vs orion 80mm ED apo?



    ok im looking at these 80 mm ED scopes the orion for $499 comes with just the scope no tube rings nothing but it has the FPL-53 ED glass is F7.5....

    On the other hand the lunt 80 mm F-7 has a strange tube ring.. duel speed focuser ..and a metal case but it doesn't say the glass type.... for AP do u think FPL-53 glass would be better then all the extras of the lunt?

    I prolly end up spending closer to $700 on the orion by time im done

    does anyone own a lunt scope ? im curious how well they are made?

    Can't comment on the Lunt, but I used to have one of the early Orion 80ed scopes - nice views, and worked well for
    AP with a small sensor CCD. Not as nice as a Tak, but a tiny fraction of the cost .
    Not the fastest scope for AP - you need more than twice the exposure time you would with an f5 - but decent performance if you're happy with the speed. Dual speed focusers are handy - especially with faster scopes - but not essential. At this price level, i'd go more by reviews than the glass type - there are a lot of other factors involved in the design, too, which can also have a big effect on how usable a scope is, and various compromises involved in keeping the cost down. If you have the budget, then the bells and whistles and faster optics are nice to have - but the essentials (after a good mount) are usable optics and an adequate focuser,
    which the Orion delivered. As with everything, you can get better if you pay more, but the Orion performs well for the price.

    yea all the reviews on the orion 80ED f7.5 seem all really good ....I love the ST-80

    the few lunt reviews I have see were really good too.. and there is a store close by were I can buy it .. so no shipping ect

    after a few nights out ive been really thinking I need to upgrade from using the ST-80 to an ed doublet or an apo triplet...

    would it be worth saving for explore scientific or the orion triplet both $799

    then there is the ES 80mm and tmb 80mm 999.99

    There's no doubt that an ED or APO beats most achromats when it comes to one shot colour imaging - the chromatic aberration gives you annoying haloes - which isn't to say that you can't get usable images with an achromat - you can, but the better corrected scopes are a lot nicer.

    As to where you aim for cost/performance, that's a personal and budget related decision - it's a bit like the hi-fi market - the high end kit performs better, but you pay increasingly high premiums to squeeze the last bit of performance out.

    Probably the best suggestion for AP is to search around for images taken with the scopes you're considering - the best images you find will give you an idea of the sort of thing you can aim at producing with the scope.

    For visual use, visiting star parties may help - and if you're lucky enough to have a local store, it's nice to be able check things out before buying - and supporting your local store makes it more likely it'll still be there next time you want something .

    I have the Lunt 102mm f7 ED Doublet. Very pleased with it. The build is solid, dual speed focusser with rotation and very smooth. I don't know what the glass spec is, I got it secondhand to give me more imaging photons and upgrade from my 80mm f5 Achro. It's not APO but seems damn close. Finish is superb. Long sliding dew shield with locking.
    I got it because I couldn't afford a true APO and so far haven't been dissappointed with performance. Only gripe might be a tiny bit of focusser tube movement when I lock it. Mine had big solid mount rings with squared top and bottom surfaces. Very useful and solid to mount other hardware on. I have guide scope and the 80mm as big finder\viewer loaded there. Don't know if that type of ring is standard with Lunts.

    yea I think im going to go with the lunt it said u can upgrade to solar with it later as well

    I imagine it will be better then my orion ST80 and it is only 419.99 and u get case and duel speed focuser and ED glass that they wont tell you the glass type lol but from some of the images I have seen it looks pretty good

    I also scored a bunch of work and have more to spend if I want too I could spend as much as $1000 maybe a wee bit more....

    I seen the TAK 60mm fluorite Q for $1600 I bet that would be a nice scope......

    or TMB 80SS...

    but ill prolly stick with the lunt 80mm and save money .. as im cheap and like to horde my money

    Did you finally get the Lunt 80mm. If yes, how does it perform in terms of chromatic aberration in targets like the moon and bright stars?

    Best,
    Marcelo
