Eye piece projection focusing problem

[Rishabh]

I have a Meade polaris 127eq, I recently got a eye piece projection adapter. When I try to focus using the 26mm eye piece it works fine but when I insert the 9mm or 6mm eye piece I'm not able to see anything (tried increasing the iso).

When I focus on a bright light nearby with the 9mm I'm able to see that light on the camera, but with planets or stars it doesn't work.
