Fitting 350D to my scope

[DavidU]

What do I need to fit a Canon 350D to my 150mm refractor, it has a 2" focuser.

At a minimum you will need:

T-ring/adaptor:

And then something to attach to the T-ring to slide in to the draw-tube of the telescope, like this:

Depending on your refractor you might need something more like extra spacer or the like, but there's a very good chance the above two would be sufficient.

EDIT: Check your refractor didn't come with either of the above. My Megrez came with an adapter equivalent to the second item above.
