    Hello everyone,

    I have trouble choosing the right telescope... I have found few I like but am very doubtful. Since I want to do some astrophotography I will go with computer controlled ones. I found this one:

    iOptron EQ-Mounted 6" GPS Computer Controlled Reflector Telescope

    does anyone have any suggestions? I have Cannon XSi and I am wondering if I'll be able to connect my camera to this telescope using adapters.

    I appreciate all the help. Thanks!

    Go to the iOptron site www.ioptron.com If the telescope is on the iOptron site, then it will perform as advertised. If not, then.......... buyer beware

    I would read through all the threads on here regarding starting astrophotography.

    The most important item is a very good solid, well tracking EQ mount. It can add up to some big dollars in a hurry. The computing power and storage for post work to really draw out the most from the photos, etc.

    The general advice is to start with visual first, then go into AP if the desire is there.

    Probably not the advice you wanted but worth mentioning.

    OK, I'm no expert on this, but I'd really recommend giving a little more information:

    1. Do you have a link to the particular telescope in which you are interested?

    2. How much astronomical experience do you have?

    3. What kind of observing conditions do you have?

    4. What kinds of astronomical sights do you hope to image with your camera?

    With that information (and maybe more that a beginner like myself wouldn't think of) the experts on the board may be able to help you quite a lot.

    The overall impression I've gotten from reading what the experts have been posting is that trying to do serious deep space photography requires a telescope of at least 8 inches with a very good (read expensive) mount and tripod - and usually isn't something done well by beginners such as myself. Webcam astrophotography seems to be a bit less demanding of telescope and observer - but can still be challenging.

    And yes, I am willing to bet that you can get adapters to fit your camera to that telescope. If you are interested in an iOptron you might want to talk to them about that as well.

    Edit: I recent bought a used Celestron C8 nice and cheap. It looks like it was purchased in 1984 or 1985 and was intended for astrophotography. Well, the T-ring adapter and the tele-extender (both expected to be used a lot of astrophotography) appear almost unused. Point is that if you've got the money it is pretty easy to buy the telescope and the adapters and such to do astrophotography but actually getting good photos seems to require a surprising amount of determination and technical expertise as well as the expensive equipment. FWIW

    Thanks guys,

    this is my concern: since I don't have big bucks, only few hundred I can spare at the moment... up to $600 I'd say, I would like to go with a scope that gives me an opportunity for AP. I wasn't going to buy the one for AP at first but than I realized I should since I have a decent camera. I would definitely play with observations first and work on the photography once I get comfortable enough with sky.

    Thanks for the suggestion,

    first of all:

    I cannot post the link just yet but

    protelescope.com/storefrontprofiles/DeluxeSFItemDetail.aspx?sid=1&sfid=95134&c=192328& i=250749694

    than, I have no experience with astronomy but I can tell you that I am pretty determined and I do work hard until I master subjects I like. I am pretty confident about this one too.

    I will be able to get out of town, away from the lights... at lease few miles away from the closest lights.

    Unfortunately I have not big money for this, not at the moment.. that's why I am trying to get something that fits both, observations and some AP. I've read that for DSO you will need at least 6" and I know if I choose to go with 8" and computer controller, it would be too expensive for me, atm that is.


    Thanks for the quick replays

    OK, I'm getting increasingly uncomfortable with your choice.

    As near as I can tell, this is the one?: Black iOptron EQ-Mounted 6" GPS Computer Controlled Reflector Telescope - or maybe something like it?

    If so, I'm going to nearly beg you not to get it unless someone here has experience with it and tells you that it is far better than I suspect.

    It looks to have a hybrid AltAz/Equatorial mount which looks very flimsy and as best I can tell, the tripod looks awfully wimpy as well. I think you'll be horribly disappointed with any astrophotography attempts using this set-up. That mount may be OK for visual observation but I simply can't imagine your getting decent photos with it. You'll also note that when they're talking astrophotography they want you to buy some rather wimpy little CCD eyepieces so we're essentially talking webcam astrophotography as the most even they are claiming you'll be able to do.

    Seriously, before I'd buy that thing I'd get a nice 6 inch GOTO Dob from someone like Orion: Orion SkyQuest XT6i Computerized IntelliScope | Orion Telescopes

    You could still do useful Webcam astrophotography, and do it on a solid mount instead of what appears to be a wimpy tripod and a rather unstable mount. What's more, you'll get it cheaper and be able to get a few goodies to put on it.

    FWIW.

    Edit: I also saw where someone said that iOptron makes those tripods too short so you would likely have to have a good observing chair to make viewing tolerable - say another $120?

    I was thinking a bit more. . . Not always a good thing?

    You really might want to haunt Craigslist for a while. From time to time you can come up with some pretty interesting deals.

    I got a fork mounted Celestron C8 with a good tripod, wedge, several decent eyepieces, T-ring adapter, tele-extender, a camera mount, AccuTrak mini drive, etc. for $200. There were some optical problems but I should end up with a pretty decent scope with which I might actually be able to do some decent (not great) astrophotography for less than the $600 you are aiming at.

    You might get a better deal than I did. . .

    Decent scopes to consider for introductory AP may be the Meade ETX series of scopes. They are within your budget, and would allow you to get some basics established without destroying the wallet. If I've learned anything about amateur astronomy, scopes are kind of like Lay's potato chips...you can't "eat" just one. Especially where AP is concerned, respectable budgets tend to start around $1K and the skies the limit from there. Once you get comfortable with visual astronomy, learn the sky, and enjoy what you are seeing through the EP, you can enhance your enjoyment with some long-exposure photography. From there, who knows? Your pics could be in Sky and Telescope magazine!

    Once again, thanks guys for a valuable response.

    I will do more research on DOB and Meade. I did read about them and I do remember someone mentioning that dob is not the best choice for AP. I just read a bunch of articles here and there and picked up everything I could, good and bad. I am not going to go crazy with money but if I wait long enough and get patient with this, by next year I might be able to invest even more in this great thing. So, I will be checking Craigslist for something small for starters, something for observing only, even the set of binoculars as earlier suggested and go from there.

    Patience and patience... thanks for the advices!
