Hi there,

I've attached my canon 550D to my mead 4505 telescope but I can't focus, I've tried a Barlow lens but nothing comes into focus even on the full moon. Can anyone help :shock:

How did you attach?

The first step would be to figure out if the focal point is too close or far from where you are now.

Hi there, I've attached via the "T" adapter. I've tried inserting my camera all the way down the focusing tube then withdrawn bit by bit, Ive tried a Barlow lens too. Looking at the live view on my camera and focusing it's just not happening.

Put aside the barlow for a moment. Do you get anything near focus, or nothing at all? If you move the camera out, even so far it isn't connected to the scope any more, does that help?
