I have an older Orion Optics Europa 250 'scope with 1.25" eyepieces. I also have
a Canon EOS350D camera. I'd like to start some simple astro photography, but I'm
completely clueless as to what I need to mate the two together - just how does
the camera get attached to the 'scope?

Any advice gratefully received.

Hi Jim,

An EOS to t-thread adapter to attach onto the front of your camera.
Mine cost me £10 from my local camera shop who had a box of them under
the counter strangely.

Right-o.

You then need a 1.25" nosepiece with a T-thread that screws into the
adapter.

Right-o. I assume that you remove the lens from the camera (told you I was new
at all this) but you are still able to use an e/p with the 'scope?


You'll also need to get hold of a remote switch to fire the camera's
shutter as pressing it attached to the scope will cause you lots of
wobble. Alternatively, set the timed shutter delay on the camera so
you can press the shutter and then move back for hands free firing.

Already got that last year when I was trying to photograph lightning, so check
on that.

A 1.25" fitting is almost certainly going to cause vignetting in your
images. A 2" adapter (2" nose piece and a T-thread at the back to
screw into the EOS adapter) will lessen this greatly. However, to use
this you'd need to upgrade your 1.25" eyepiece holder/focuser.

Welcome to the money pit ;-)

You're not exactly selling this to me! :-)
