Hi guys I currently own a 12" skywatcher collapsible dobsonian but need to upgrade now to have goto functionality. It is way to expensive for me though and I can only spend up to 1200 AUD ~ 900 USD. Could anyone please help me think of some alternatives, to track and remotely control my dob? :)

 

Thanks guys!!

If you just want tracking, you could go the equatorial platform route.  If you're good with either woodworking or metalworking, you can probably make your own and save yourself a bunch of money.

I understand how the nexus II works but what do I actually use to motorise it?

 

Cheers

No motors, it's for a push-to system. You look at the screen, on phone or tablet, and as you move the scope by hand, you follow its movement on the screen to align it with a target. It's not go-to, and doesn't track. Although if you want to track you can also use an Equatorial Platform as suggested by Louis D above, which is also what I do. Although I only tend to need to track if I'm dedicating a session to the moon or planets, otherwise I don't bother. I think with a dob, pushing it to the target is quicker and easier than waiting for motors to to take it there, but that's just my opinion.

If you want to convert your dob to full goto with tracking I don't think there's much alternative to buying a complete kit to do so. It's probably not much dearer to buy a new goto scope and sell your current one but I'm only guessing that.

good luck with whatever you decide :)

Ahh, that makes sense. I, unfortunately, can't actually move it manually as I am creating a remote observatory. How much would a barely used 12 inch perfect condition skywatcher dob go for?

To reel your query back a bit, I understand you want to have a 12" telescope in a remote controlled observatory. You might get more answers if you supply a bit more detail.

What do you intend to do with it? Will it be permanently set up, set up temporarily next to your house, or set up temporarily or permanently at a remote site? Why does it have to be remote controlled? Have you considered other scope types, or ruled them out on grounds of cost? 

You can look up the prices of various options on astro suppliers websites, and reckon on a good used one being around 2/3 the cost of new.

Affordable, vintage 10" and 12" Meade LX-200 SCTs come up used on a regular basis in the US.  Not exactly new, but much better suited to a small, remote-controlled observatory than a GOTO dob would be.  I can't recall ever seeing anyone put a 12" dob in a remote controlled observatory.  Why would you?  It's a visual-only instrument.

      I have a nexstar 6se and I love it. I've only had it about a year and it's my first proper telescope. Every opportunity I'm out in the garden both looking through it and attaching my dslr to the back for fainter objects.
      I'm noticing I'm getting movement in the longer exposure photos and after a bit of googling I think it's the mount.
      So I'm looking to upgrade. I'm thinking something a little future proof but I'm not made of money so decent, reliable, cheaper end but good enough for astrophotography and with the possibility I might continue to add bits and pieces. 
      What do I need and how much am I looking? Help thanks in advance.

      Hello, I am an amateur astronomer that wants to get into deep-sky astrophotography. I already have a telescope which is Celestron Nexstar 127 SLT but it doesn't meet the requirements to take photos of wide field nebulaes/galaxies, (Ex: Orion Nebula, Andromeda Galaxy). I need some help on what to use and afford! It has to be under £550.
      I need a 70 or 80mm optical tube, with a mount that does polar alignment and can be attached to the optical tube then I need a Canon camera that can take long exposure high ISO photos and last a filter or two to help reduce light pollution and contrast the nebula/galaxy more!
      This is just for my birthday, I do not expect the best!
      I just need a beginners setup.

      Hello! I have a question on how can I mount my camera to my Sky-Watcher Starquest 130P telescope? I’ve watched so many videos about it and there’s so many different answers on what I need to do that. At the moment, I have 2x Barlow lens and a DSLR. I know that a T-ring is also necessary but is there anything more? Any help is highly appreciated, thanks! (I’m really new to telescopes and astrophotography in general so I hope I don’t say anything dumb)

      Hi! I've recently acquired a new Astromodified Canon rebel XT and I've tried to take pictures of nebulas using it but I've noticed that there are these weird black artifacts that keep appearing in my images. Would like to know if anyone has experienced this before? Or are these dirt/dust specs on the camera, filter, and telescope glass? I've attached some of my edited and raw pictures for your reference. The black artifacts can already be seen in the raw image of the horsehead nebula and after stacking I think it got amplified. Anyway, advance thanks and I hope everyone's doing well.

      Hello all,
      This is my first post on SL, so please correct me if I have started this topic in the wrong place. I am also relatively new to astrophotography, so please ignore my naivety!
      I had some clear skies last week, so decided to do some lunar imaging with my new(ish) ASI224MC. I captured my frames in SharpCap as RAW24 AVI files, stacked in AS!2 and processed in Registax and Photoshop. When i got to sharpening in Photoshop, I noticed a sort of mosaic pattern over the image, which took away from some of the detail, and really ruined the image the more I sharpened. I did a quick search and it turned up with 'debayering'. This is a completely new concept to me and all of my attempts didn't seem to improve the image at all (perhaps I was debayering in the wrong order?). I have attached some images and also my some of my SharpCap settings in case they are of help.  
      COLOUR SPACE: RAW24
      CAPTURE ARE: 1304x976
      OUTPUT FORMAT: AVI files (*.avi)
      EXPOSURE: 0.29ms
      GAIN: 282
      Thank you in advance
      Regards, Josh.
