>>3028845What you want is a tracking mount. Either an EQ3 or EQ5 will do with a decent polar scope (clock-like markings)
If the scope has a tracking mount all you need is an equatorial wedge and the polar scope I mentioned. It will be great for planetary photos but don't expect to have any results with DSOs and nebulae, the scope is too long and dark, you need a wider field of view and bigger aperture for nebulas.
It is better to get an 80'' small refractor around 400mm focal length and an EQ3 tracking mount. You can also use old manual focus telephoto lens as a scope, 300mm on APS-C will give good results, 135mm and 50mm for wider stuff. You will need 50mm for the Orion nebulae complex for example.
Consult your local astronomer's club and shop for more specific help, /p/ is just dicking around with astro except for that swiss reflectorfag guy.
