      Gonna say someone is going to make another sad joke about Uranus, and you have already proven before I had a chance :D

    Saturn looked about as good as this: https://youtu.be/me5mxKAu_uM?t=18
    Jupiter looked similar to this: https://www.farnham-as.co.uk/2010/12/jupiterand_galileanmoon…

    It's been probably 8 to 10 months since I've used it so I'm going off memory, I've just pulled it back out about a week ago. Once the weather clears up I hope to spend a few nights looking at things with the kids again. I'd like to see if I can find some DSO's this time instead of just looking for planets.

      The fact that you said you purchased this 1 year ago and the last time you used it was 10 months ago does not instill me with confidence.

  Hi Op, my wife always has a keen interest in this as well but we have never quite figure out which telescope to get. The "good" ones are always priced beyond our reach. Do you know if it is possible for me to use an adapter to connect this telescope to my DSLR to capture images of saturn, moon, etc and expecting the image to be sharp?

  Edit: What do you think of these, priced about the same?

    I would say you probably wouldn't be able to connect your DSLR to this scope, I bought a Celestron NexYZ Smart Phone Adapter to try and take some photo's with my Pixel XL and it really struggled with the combined weight of the adapter and phone. You could possibly try and hang something off the front of the scope as a counterweight but I haven't tried that so I don't know how it would go.

    I'm only a beginner in telescopes myself and I'm still learning so I am hesitant to say something is good/not good without first trying it as I don't feel like I have enough experience to be able to do that just yet. From what I have read the 130mm reflector should be better for deep sky viewing than the Cosmos 90mm refactor, but the Cosmos should be better at viewing planets.

    I've been reading up about the 130EQ vs the Skywatcher 130 Dobsonian for the last couple days actually and it seems that a lot of people recommend the Skywatcher 130 over the 130EQ (https://shop.australiangeographic.com.au/skywatcher-130-dobs…). I've read some about some complaints with the EQ mount but the skywatcher is limited to being set up on a table due to the smaller mount. I've also read that EQ mounts are harder for a beginner to use as you have to align them with the celestial pole, I have never used one myself though.

    I'm not sure if it's clear in the post above but the Cosmos is a "go to" telescope. You download the app and connect to the telescopes wifi network and select a target and the telescope moves directly to it (after you align the scope first). It also has the option to purchase the celestron AZ hand controller if you wanted instead of using the scopes wifi. For the price of the 114AZ I would personally go for the cosmos for the ease of the go to system. With a manually operated mount you will need to track the object through the sky. Once you've aligned the cosmos mount and tell it to go to an object, it will follow the object through the sky. I have pointed it at Jupiter without aligning it and it's surprising how quickly it moves out of the field of view without automatic tracking.

    Edit:
    You also need to collimate reflectors from time to time which is something (as far as I'm aware) you will never need to do with a refactor. I have no experience with it myself but it doesn't look too hard if you have a look on youtube.

      Thanks mate. I will do more research.

    You need to do alot of research. There's the right telescope depending in target your after. Best thing would be to check photos and equipment used on astrobin.com if your just taking photos of bright objects only moon and planets then you could get away with cheaper equipment. Best to get 2nd hand, maybe 4", 6" or 8" SCT if your just after moon/planets. Should be able to add adapter and DSLR

    Astronomy clubs have recommended Bintel telescopes to me as decent value for money: https://www.bintel.com.au/product-category/telescopes/?v=6cc…

    I've considered buying one but can't offer much beyond that.

      Thanks mate. A lot of choices in that website!

  Anyone considering a telescope should first join a local astronomy club and visit observing sessions. Australia has a good astronomy forum with lots of good advise on what telescope to buy for what purpose. iceinspace.com.au also the American one is cloudynights,com . Australian geographic is generally overpriced compared to other shops. In Australia it’s better to buy used gear from the forums , much less expensive than new.

    donigan on 19/05/2019 - 08:32

    I agree that they can be overpriced, they wanted full price when I bought mine last year and I managed to find it for $300 less at a different store. It is now $180 cheaper than what I paid. For what it is I think it's a bargain at this price.

    Good advice.

    I used to have a decent telescope but setting it up was a drag. Just use binoculars now.

  It might be better to spend a little but more for a 8" Dobsonian telescope. $529. Sure it won't have goto features, but it's simple to use and have a better view. Downside would be learning how to use star charts and working with image drift. Ie. Depending on magification, you can see the target drift off center which might need a few nudges to bring back to center for the duration of your view. Goto will recenter target automatically.

  If you join a local astronomy club some might have scopes that they loan out to members if your not in a hurry.

  annoying. Bought one of those for 479 a month or so ago.

    I saw same diameter 90mm Meade Goto refractor on gumtree for $150. I should have grabbed it just for my son, but reviews seem to say its a bit shaky.
