    Wow! Thanks for the great post. I only recently started thinking about astronomy. Binoculars are great, but I have trouble keeping my arms steady enough to get a good look at anything. Any good ways to keep binoculars steady?

    Tripod? Or even monopod.

    Really cheap ones can go for < $30, but you get what you pay for.

    I'll bet if you ask around your fam & friends, someone will have an old tripod they don't use anymore.

    most tripods have a hook on the bottom, you can by small sandbags from any video or photography shop like BHvideo.com
    just mount the sandbag on the hook and it will increase the tripod's stability and keep your binoculars extra steady. Just make sure the Binoculars you have come with a screw mount so you can attach them to a tripod.

    EDIT to my last post: Porters.com is aparently out of business, As you can see, I shop at B&H a lot more :)

    I have a moderately priced Newtonian that I bought at a steep discount (maybe because it didn't have the auto tracking motors and other high end toys, but still costs some bucks) that I bought to replace a much lower end Newtonian that I had earlier. And it magnification and quality are really good. And I sometimes take it out and set it up. I'm glad I have it. But 90% of the time, I use binoculars. Aside from viewing the Jupiter and Saturn, I get no other real value out of it. If I use my Barlow adapter and lens to get the supposed 250 X magnification, I am constantly adjusting as the object is running out of my field of view. That is the one nice thing about buying a unit with a tracking motor. But that would require even more effort to set up. I am a 5-15 minute observer. I don't attend all night (or even a couple hours) events. Hence the Good pair of binoculars.

    I might even get enough enjoyment out of a spotting scope of 50-60X (I don't have one, but I rarely use my telescope above these ranges either, due to keeping the object in my field of view). Very simple, point and look. Primitive, down and dirty. But then I don't hang out with the amateur astronomer crowd. You really might enjoy that.

    About binoculars. Money doesn't always buy the best set of glasses. I have several pair, my most expensive are actually my poorest for night viewing. It is a high end name brand 7-21X50 variable magnification set (I think Bausch, but I don't use them enough to even remember). I couldn't pass them up at 50% off. They're ok, but color is dulled out (made for the deer hunter or possibly winter viewing during the day on snow, which might explain the less that stellar performance??). My best set is a modest 10X50 (some cheap set that I pick up and marveled at how clear the image was) and my most used is a 7X40 due to its much lighter weight and good optics. The 7X40 was my first set and wasn't expensive but a good brand name that I still use. The reason I have a few sets of glasses is so I can share with my guests if anyone wants to join me (once in a while the wife, but she would rather see something in the big telescope, looks and is almost always disappointed aside from Jupiter and Saturn).

    So my advice isn't as an enthusiast but a casual user.

    One thing to note here. A spherical mirror is just fine for either small apertures or long focal ratios. For an 8-inch aperture, the f-ratio needs to be about f/12 in order to be diffraction limited with a spherical mirror. Anything faster than f/12 with an 8-inch aperture will not be diffraction limited. For smaller apertures you can move to a faster f-ratio and still be diffraction limited with a spherical mirror since the airy disk increases in size with decreasing aperture.

    Agreed, but 8" f/12 is a bit of a beast (and a specialty item, not found so easily I think), and decent parabolic mirrors are really affordable esp. Chinese ones. Good or even great starter scopes like small (say 6"f/8) dobsonians are available for $300 or so.

    Certainly. Newts are cheap to buy at almost any aperture.

    Hello, nice thread for beginners.
    Can you tell me how are these for beginners:

    I have not had the opportunity to observe through any of those instruments, nor try out the mounts. Orion is quite a popular company, so if you join a local club, you may get to try some of these instruments and compare them to others. That is the best way to make your choice before you spend a dime. Good luck to you.

    My first telescope was a cheap department store 10X to 30X 1 inch zoom handheld with a tripod mount.
    With it on my camera tripod i stumbled across Saturn. It only looked like a black-eyed pea , but even that was thrilling.

    So i took next step and ordered a Celestron "Comet Catcher."
    It is a small Schmitt-Newtonian , not very expensive .
    Using just a camera tripod i had a lot of fun with it.
    It did a great job on last visit of Halley's Comet before the tail fizzled out .

    I never progressed beyond that little beginner's scope. Still use it.
    The Schmitt lens at end is nice because it keeps dust off the main mirror.
    It'd make a great finder for a serious telescope.

    Dad's 70th birthday was coming up. Retirement getting tedious, he was tiring of making birdhouses for the neighbors..
    He'd wanted a telescope since he was a kid so i ordered him an 8 inch Meade mirror and mounts.
    We built a redwood tube for it. It became the darling of local astronomy club.

    Advice given above regarding a hookup with local enthusiasts is most excellent. Do-It-Yourselfer's are always eager to help out.
    The guys at Southern Cross club showed us how to improve our mirror mounting scheme
    and how to make an equatorial mount from plumbing fittings.

    I found Petersen's Field Guide to the Stars and Planets a pretty good starter-out book.

    My first telescope and the only one I have and ever bought till date is the celestron firstscope.its a 76 mm dubsonian type reflecting telescope.it is pretty amazing actually.the moon looks awesome through it and you can see Jupiter too.I absolutely love it.I am looking forward to buy an advanced telescope than it but I think that firstscope is a perfect beginners telescope.

    The best scope for you is tne one you enjoy using. Sounds like a success on that point. Beyond that you must decide what will please you in the future. Don't worry about getting down to magnitude 20. Eyepieces are your best friend. A good eyepiece makes a scope your slave, not master- and they are aperature insensitive. The best views for any aperature size comes from high quality low mag eyepieces.

    So, in your opinion is the Orion Funscope fine?
     
  19. Oct 27, 2015 #18
    The funscope is similar to my telescope(celestron firstscope).there is no difference between them except the company.in my opinion it is perfect for an amatuer.I myself am yet learning.and firstscope seems to be a decent scope to start with and so is funscope.

    What sort of objects have you seen?
