Focal problem

[roebuck]

I have a skywatcher 80ed ds, but unable to focus with camera using x2 meade barlow and 1.25 t adapter.

do i need to increase focal length with another extention adapter? any help would be appreciated.

If so what type of adapter needed.

Are you able to unscrew the optical part at the end of the barlow?

If so take this off and see if you can now focus.

My guess is that you need to add an additional extension tube. An easy way of checking this would be to place your diagonal (assuming you have one) in between the Barlow and the focus tube.

Unscrewed the optical part from barlow and this will focus.

I am only able to put the barlow mounted on top of the diagonal then attached to camera as it is a 2" scope and this will not focus.

As Steppenwolf said, you will need an extension tube.

Have a look through these pages.
