    Question Will You Start at a 80mm Refrator



    Hello friends;
    I hope you are having a nice day!
    I am working in the office for 8 hours per day. I want to ask what telescope do you get to start astronomy?
    Will you start at a 80mm refractor?
    please recommend, Thanks very much!

    Clear skies

    You can start with any size telescope - I started with a 60mm refractor. Of course the larger the telescope, the more you will see. Many on this forum would recommend starting out with a pair of binoculars. It would be hard to suggest a telescope without first knowing approximately how much you might want to spend for one.

    My first telescope was a 70mm f/10 refractor.
    A 80mm will let you see a lot.
    Is there a specific model you are looking at?

    my friend has a 60mm/420mm refractor in hand, I can do normal viewing with that. So i am thinking to buy one for myself. i think the 80mm will better than the 60mm. it must be true.
    i know the telescopes expensive, so that the price should be afforsable. about $150, maybe.

    Hello Rita,

    my starter has been an 80mm achromatic refractor, assembled from surplus optics, and a pair of binoculars from my grand dad. This was about 60 years ago.
    Anything like a 100mm Sky-Watcher refractor would be a good starter, and so the 25x100 binoculars.
    Best,

    I don't focusing on which model. I can do normal viewing now. my friend has telescope 60mm/420mm. I used it with my smartphone to take some photos of the moon.
    I want to view the Jupiter and Saturn. should I buy a reflector or a refractor? does that matter? and what should I pay attention to on the telescope?
    I know astronomy hobby is expensive. I am saving money for it. Thanks for your recommend.

    Hello JG;
    Thanks very much my friend. have you used 100mm Sky-watcher refractor?
    Should I buy a new one, or a second-hand? I am saving money.

    Hello Rita,

    the Sky-Watcher refractor I have is the 6" F/5 achromatic, and it is a powerful piece of optics to be taken quite seriously.
    It is of course customized with the fine focuser, dielectric 99% reflectivity mirror on quartz substrate, and filter wheel,
    http://www.astronomyforum.net/member...%3D131513.html

    Attached are some single frame shots of Moon captured with a camera hand held behind an eyepiece on this refractor.

    Should I replace this scope, then it would be one of the best ever made fast 6" refractors designed by Kasai in Japan,

    https://www.teleskop-express.de/shop...eb-Auszug.html ,

    also known as Nerius in the U.S.

    When you go 2nd hand shopping for any refractor whatever, then take with you the f=10mm Baader Eudiascopic eyepiece.
    Any terrestrial view should resolve the finest details with a very high contrast, absolutely pleasing,
    and hardly any color fringing.
    The Baader Eudiascopic is the Masuyama's remake of the Zeiss Astroplan,
    and this eyepiece, as its rebrands in the U.S., is not forgiving.

    So, theses are just some comments on the Sky-Watcher fast achromatic refractors, and the 100mm would certainly be a very good choice.
    Testing the 2nd hand refractors before purchase is important, of course.

    Best,

    JG

    It's not just a matter of buying the telescope itself, it will need a mount of some sort. A good mount can make all the difference as it will hold the telescope steady enough when viewing and can also have slow motion controls. These are important as you will be able to compensate for the Earth's rotation to keep the object in the field of view.

    I took a quick look at several China online sites (Alibaba, JD, TMALL). It looks like you could get a small equatorial reflector telescope (114 -130mm) or a small refractor (70mm - 90mm) at or a little above your price target. I think in this price range, you would do best with the largest refractor you can afford. For used, I like JD's advice to look through it before purchasing to make sure the views are sharp. If you intend to look through the telescope only at night and not during the day, you might want to buy one that has an equatorial mount. You mentioned looking at planets, so make sure the telescope you buy has at least one eyepiece that gives over 100x in magnification but not not higher than about 2 x the telescope objective lens diameter in mm.
