good astrophotography telescope?

I have a 10″ dobsonian telescope with no EQ mount. I also have a Canon EOS Digital Rebel DSLR camera (not modified) with an adapter to a telescope 1.25″ and 2″. I am looking to get a nice 10″ telescope with a focal length of about 1750-2000mm. I want a great tracking tripod that I can get 10-15 min exposures. I will be able to get a job next year so I don’t have a major income to help feed my obsession with space. What I’m trying to say, is that I need a telescope at around $2000. Feel free to tell me about others that are more though. Also feel free to tell me about any 12 inch telescopes as long as they are all on a tripod tracking mount.

Thanks!

Well, …, in your case I’d why don’t you by a really good high end banded equatorial mount (e.g. losmndy or vixen) and use your 10″ OTA. The mount is really the critical component to astrophotography. A 10″ Meade LX200-ACT will cost you $3500, then you’ll need the $400 supper wedge, and a ~$400 autoguider to guide the scope (not to mention adapter rings and such for your camera). That’s roughly ~$4,300. Also you need to consider weight of the scope the LX200-ACF (when fully assembled) weighs ~120lb. You may also need to attach a set counter balance weights to the scope (of course that will be extra). So, IMHO, you should maximize you current investment by just buying the high end mount. BTW you’ll still need the autoguider.

1.25 Orion Universal Camera Adapter $36.99 The 1.25″ Universal Camera Adapter allows attachment of a camera body to reflector and refractor telescopes for either prime-focus or eyepiece-projection photography (hence the term universal). The adapter slides into the eyepiece holder as an eyepiece normally would. This universal adapter is composed of two detachable parts: a prime-focus adapter (or T-adapter) for prime-focus photography, and a fixed-length or variable extension tube for eyepiece-projection photography. A thumbscrew in the extension tube holds the telescope eyepiece in place. This combination of prime-focus and eyepiece-projection camera adapter has a non-variable barrel design that allows a fixed projection distance for eyepiece-projection photography. Fits reflector and refractor telescopes with 1.25″ telescope eyepiece holders. This Standard Universal Camera Adapter is precision made of black-anodized aluminum and is compatible with 1.25″ telescope focusers and many 1.25″ telescope eyepieces (some eyepieces have housing diameters that are too large to fit inside the adapter). The barrel of the adapter is threaded for filters. A T-ring for your specific camera model (sold separately) is required to couple your camera body to the universal adapter.

1.25 Orion Variable Universal Camera Adapter $52.99 The 1.25″ Variable Universal Camera Adapters allow attachment of a camera body to reflector and refractor telescopes for either prime-focus or telescope eyepiece-projection photography (hence the term universal). The adapter slides into the eyepiece holder as an eyepiece normally would. This universal adapter is composed of two detachable parts: a prime-focus adapter (or T-adapter) for prime-focus photography, and a fixed-length or variable extension tube for eyepiece-projection photography. A thumbscrew in the extension tube holds the telescope eyepiece in place. This combination of prime-focus and eyepiece-projection camera adapter has a sliding barrel design that allows variable projection distances. This allows for slight changes in magnification without swapping telescope eyepieces when performing eyepiece-projection photography. Fits reflector and refractor telescopes with 1.25″ eyepiece holders. This Variable-Power Universal Camera Adapter is precision made of black-anodized aluminum and is compatible with 1.25″ telescope focusers and many 1.25″ telescope eyepieces (some eyepieces have housing diameters that are too large to fit inside the adapter). The barrel of the adapter is threaded for filters. A T-ring for your specific camera model (sold separately) is required to couple your camera body to the universal adapter.

Orion SteadyPix Telescope Photo Adapter for iPhone $59.99 Take beautiful astrophotos through a telescope with your iPhone! The SteadyPix iPhone adapter securely couples an original iPhone, iPhone 3, 3GS, 4 or iPhone 4S to a 1.25″ telescope eyepiece so you can take high-magnification pictures through the telescope using the iPhone’s built-in camera. The sturdy steel bracket allows the iPhone’s camera lens to be positioned directly over the telescope eyepiece eye lens for afocal eyepiece-projection photography. Capture high-resolution images of the Moon’s cratered surface, bright planets like Saturn and Jupiter, and with practice, even some bright deep-space objects and the International Space Station (really)! The fun doesn’t stop at sunrise either. Use the SteadyPix iPhone adapter during daylight hours to take superb high-magnification snapshots of distant wildlife and scenery, and with a properly sized solar filter, sunspots on our nearest star – all with your iPhone. The Orion SteadyPix Telescope Photo Adapter lets you display a live view of the image projected by your telescope on your iPhone screen. Now you can share beautiful real-time views of the night sky with friends and family by using your iPhone as a mini telescope display monitor! The adapter can also attach your iPhone to a photo tripod for steady wide-field pictures without a telescope. Includes felt-lined eyepiece clamp that fits standard 1.25″ telescope eyepieces with housing diameters up to 1.5″. A larger clamp for bigger eyepiece housings sold separately.

Orion 1.25 Imaging Flip Mirror Camera Adapter $19.99 This handy adapter threads into our Orion Imaging Flip Mirror (sold separately) to allow use with 1.25” sized astro-imaging cameras; such as our StarShoot Solar System Imager, StarShoot Planetary Imager and AutoGuider, and our StarShoot USB and Video Eyepieces (imaging cameras and eyepieces sold separately). Once installed on the Orion Imaging Flip Mirror, this 1.25” Camera Adapter enables you to acquire and focus an object using a 1.25” telescope eyepiece while an astrophotography camera with 1.25” nosepiece barrel is attached to the same telescope. You’ll be amazed at how easy it is to achieve optimal focus for imaging with smaller cameras when using the Flip Mirror and Camera Adapter combination. Once the 1.25” Imaging Flip Mirror Camera Adapter is installed on the Flip Mirror, simply insert your imaging camera’s 1.25” nosepiece into the adapter and secure in-place using the adapter’s thumbscrews. You can then place any preferred 1.25” telescope eyepiece into the upper 1.25” holder on the Flip Mirror, and manipulate the flip switch to alternate between the imaging camera and eyepiece. Using the eyepiece, focus the view, then switch back to the imaging camera to capture an exposure. Your snapshots and extended exposures will conveniently be in focus! The Orion 1.25” Imaging Flip Mirror Camera Adapter is made of black anodized aluminum, and features two thumbscrews for secure installation of imaging cameras with a 1.25” nosepiece barrel.

Orion 2 to 1.25 Precision Centering Adapter $34.99 This clever adapter precisely centers any 1.25″ accessory in a 2″ focuser. Whereas standard 1.25″ adapters use a thumbscrew, which pushes an inserted barrel laterally, i.e., off center, the Centering Adapter employs a helical compression mechanism that precisely centers the accessory as it is tightened in place. This adapter is especially useful with reflector telescopes for critical centering of a collimating device. It’s also ideal for centering eyepieces and imaging cameras on the center axis of a telescope’s light path. Made of machined, anodized aluminum, with a knurled twist-lock ring. Barrel is threaded for 2″ filters.
