    Hello, I may be off topic or in the wrong spot on the forum but I have a question about a Celestron Nexstar 120 SLT refractor. I bought the scope a few months ago and as with everything I Get, I try to get all the accessories that I can to go with it. Well, it started raining a week after I bought it and I have seen the moon only once and that was on Christmas Day. Can anyone with this scope give me some positive input. I want it for seeing and AP so I got an Orion Starshoot Solar System color imager, got the software all loaded on a small laptop, got a focal reducer, a polarizing filter and am ready to rock. If anyone that has this scope or that has owned this scope, would you advise me on whether it is going to be inefficient for seeing DSO? I like the scope myself, seems to be well built and all the gear, including the wifi adapter I got to run the motors via Tablet works great, just wanting to hear from some folks that have this scope. As my enthusiasm grows, I will surely get me a nicer scope. I hear the MAKs and the DOBs are very popular. I have great skies here when the skies are clear, especially up on Mount Hood. At night you can see stars and meteors and planets really well, as there is no light pollution. So dark you cant see at all without a flashlight. I will be hoping to hear from some of you soon. I cant wait till things are looking up.
    Thanks,

    Having recently received my first refractor, a Explore Scientific Ar127, about a month ago, I can safely say that I do indeed like it more than my old 6" Newtonian reflector that I had used previously (sold it on eBay in order to help gather the money to pay for the refractor!).
    The Ar127 does have some false color, which can be a little annoying, but it did noticeably better on Jupiter, with the bands being displayed rather prominently, and the Jovian moons looked terrific with the sunlight bouncing off of them!
    The downside is that due to the increase in weight and length, my old CG4 mount has a harder time in trying to hold a steady image, especially at 117x...
    The flipside, is that it is now much easier to find objects with my refractor than it was with my old reflector, and I now get these amazing wide field views with pin point stars, where before the view was much narrower, and the stars had noticeable diffraction spikes in them.

    "Disadvantages of a Refractor Telescope


    most expensive per inch of aperture than other telescopes
    price of refractors escalates highly after 3 inches
    affordable apochromatic refractors are very small aperture which will be outgrown by many astronomers over time"

    Well, many people would say this is dead wrong. The biggest change in refractors is how affordable they are now. An excellent 4-inch achromat is 200 - 300 and a freaking 5-inch ED/APO is less than 1500.

    It certainly isn't dead wrong, but I would seem that refractors have become more affordable.

    I would certainly disagree with the last statement. A nice small quality apo is not something you really out grow. No more than binoculars or a 20" dobsonian.

    No I did not miss it, I personally feel that the refractor is the best "all around" telescope be it an achro or apo.

    This thread is 7 years old and refractors have come down a lot in price. All telescopes will have advantages and disadvantages, no one telescope can do it all.

    Hondo I agree with you 100% Each type has a plus that the others don't. Unfortunately my poke at 25(ish) year old wisdom was taken as serious.
    The sooner everyone on earth has a refractor to play with the sooner we will be able to achieve world peace.

    Well, we certainly agree there. But I can't see me out growing my ED80T CF. I got it for a specific purpose, and it is fulfilling that beyond my hopes. And still at below 50% of my mounts weight rating, from the Vixen up. Because I did my homework.
    I wasn't interested in an Achro, nor reflectors. But astrophotographic refractor telescopes (ED APO Triplet) are still bringing big prices. Buy once, and be done with it.
    Never did hear of anybody saying that picture was taken with too good of a telescope....
    They ain't Walmart scopes. Because they wouldn't move off the shelf like Achro's do.

    And sorry if I took your post seriously. Maybe next time you could use a smilie , or a laugh , ya know, just so folks can see your sense of humor....
