Hi Martin,
This is the camera adapter i use for afocal photography

With regard to distance from the eyepeice, i found around 10 - 20mm from the lens works well otherwise you end up capturing the edge of the eyepeice. With your sony you would just attach as seen in the picture line everything up and away you go. I usually use a 15mm ep and just use the zoom on the camera to get a close up on the moon or planets.
Hope that helps a bit,
Cheers
Scott
