Using a point and shoot

[simmo39]

Hi, not sure if this isnt going to get laughed out of the place but. I have been using my fone to get some images of Saturn, which i am pleased with but last night i found that my point and shoot camera when on the lens fits in perfect into the tube of the scope ( SW 127). the only problem was that i couldnt get focus. is it me being naive or can this be adjusted by using a tube or other means.

I know the skywatcher 130 & 130p wont reach focus with a DSLR, not sure about the 127? with the others its a case of insufficient inward travel to focus.

Sounds like you are trying to do afocal imaging - i.e. camera with lens plus eyepiece. This is quite possible, but you will need something to keep the camera firmly attached to the eyepiece.

Thanks for the replys. Im using a Kodak sure shot and the lens of the camera fits into the scope eyepiece socket perfectly. I tried it directly into the scope and also via a 2x barlow but in both cases couldnt get focus, although Saturn was visible on the camera screen as a fuzzy blob. I was just wondering if a longer tube attached to the scope would help.

You will need to image through an eyepiece ( afocal imaging ) . If you try to shoot without an eyepiece ( prime focus ) you will not get a focused image on the sensor, this is only possible with a DSLR.
