    Default Buying a Telescope - One of these Refractors, or this Dobsonian?



    I'm fairly new to telescopes, I have a small Dobsonian telescope but I could barely say I have any real knowledge, however, I am dedicated. Recently I have become much more interested in astronomy, but to be honest don't have to much of an idea when it come's to buying a telescope. I watched a lot of videos and did some research so I have some understanding, but I wanted to get an opinion from a reputable community. I've narrowed it down to a few choices, but by all means, if you have anything else you'd like to recommend please do so. I'm looking to spend up to $1500, I know that if I get a refractor I would want it to be apochromatic, because although this is my first time buying a serious telescope, I don't want to cut any corners. I am also most interested in viewing planets and want to begin astrophotography. I still do want to look at deep sky objects too though, so what can you guys recommend to me? Also can you explain how far I'd be able to see with said scopes and give any extra information possible? I live in the city, but also have a place in the country with superb a view even without a telescope, you can see the big dipper, small dipper and there are more stars in the sky, then there is black. Thanks a ton!

    Here are the scopes (they are hyperlinked):

    Orion Sirius ED80 EQ-G: This one I've been really leaning towards, I do want to learn to map the sky myself, how ever I do also want the tracking capabilities that a go-to mount brings. My question for these scope is how far could I actually see?

    Celestron Advanced VX 6 Refractor: This scope I just found, I see it has a 150mm diameter oppose to the ED-80, and apparently is said to have higher magnification. The reason I'm asking is because I've been told to not trust what the manufacturers say. Would this see further than the ED-80? If so why is is less expensive?

    Orion SkyQuest XT10g: Or I'm possibly considering this, what pros and cons would this have oppose to the refractors? I defiantly want to see planets in high detail, but am also very interested in seeing deep sky nebulae and such. Also since this dobsonian has a go-to mount I'd assume it has at least some capabilities of astrophotography.

    Welcome to the forum.

    (You can edit a post with 15 minutes of posting it, then it becomes permanent.)

    All those scopes and mounts are good. The ED80 on the Sirius mount might be the best for astrophotography. The 10" Dob will be the best for eyepiece viewing.

    How well you can see depends on the aperture of the scope. A larger aperture will allow you to see more detail and to use more magnification. The maximum reasonable magnification of a scope is equal to the aperture in millimetres. So, for viewing, you want the biggest aperture you can afford. For most people, this means a Dobsonian.

    If you have your heart set on astrophotography, a Dobsonian is not a good choice. Even with a goto's tracking ability, field rotation from the alt-az mount will prevent exposures longer than about 30 seconds. And Newtonian telescopes (all Dobs are Newtonians) are often unable to bring a DSLR camera to focus.

    I bought my AT-90 APO on Astromart for $995, which was an incredibly great deal! It was brand new. The only time it was out of the box was for the seller to take a photo of it to put it online! Great grab & go! Check out Astromart. You may get lucky! Just my two cents. Good luck!

    Hi There Syadin.
    Welcome to the forum.
    A great place to find good equipment in Canada is at http://www.astrobuysell.com.
    I have in the past picked up a few items here.
    Something like this may be of interest to you. http://www.astrobuysell.com/propview.php?view=28166
    Something in this price range may leave you enough funds for an adequate mount to suit your purposes

    Regards
    Bob

    Welcome Syadin. If you are looking to buy new I recommend Canadian Telescopes - prices are pretty good (for Canada) and shipping is free. KW Telescope also has a good reputation.
