which telescope for D700 and astrophotography

Nope... it uses a focal length extending/correcting optic in the eyepiece tube. It doesn't have a 2" focuser, and will not have enough back focus to produce a sharp image on your camera's sensor. Plus.. it's a cheap refractor scope... the CA will be abysmal!

The cheapest scope that will guarantee enough back focus, and has a 2" focuser is the Skywatcher Explorer 150P

It lacks the "Go To" computer navigation though.

Another reason the scope you listed isn't really suitable is because it uses an alt-azimuth mount, so when it tracks objects for long exposures, you'll get field rotation. You need an equatorial mount for long exposures, but motor driven equatorial mounts are expensive.

You can get add on motors for the 150P I listed however....

I use the above scope, mount and drive, and even with this you'll only get around 1 minute or so without movement showing.. even when correctly polar aligned. For proper astro photography you need a guided mount, and these start at around £700 and need a second guiding scope.

Astro photography is NOT cheap.

What were you wanting to photograph? Moon? Planets? Deep sky objects such as nebulae and galaxies?
 
my wife got me a celestron 130 slt as a surprise birthday present, its great for casual star gazing, if you wanna get into astro photography then its a long expensive path, but you could buy a cheap adapter and screw your slr onto the scope, depends how serious you feel, just learn how to use the scope first, am now subscribed to loads of astronomy forums as well as photography! good luck!

I wouldn't recommend that scope as a starting point for astrophotography.
The focal lenght is quite long at 1000mm and the mount is definitely not substantial enough for photography.
To point a 1000mm focal length scope ( or lens) you would need to spend a lot more on the mount alone to allow exposures long enough for reasonable results.

I would suggest you use your existing camera and lenses and mount them on a basic german equatorial mount with a motor on the RA axis to track the stars.
(Something like a Skywatcher EQ3-2 Deluxe Equatorial Mount). With a motor that costs about £270
You'll get massively better results with that set up and it will be more versatile-
The shoter focal lengths will allow much longer exposures (a few minutes)before mount aligment and tracking issues come in to play.
Wide angle lenses for meteor showers, 135mm for constellations and say 200mm+ for open star clusters and nebula.
Once you gain experience with the shorter focal length lenses, use longer ones and I'm sure you'll eventually look at buying a good quality refracting telescope of 400 - 500mm FL and then even a bigger more accurate mount!
And on it goes :-)
