Problems with Saturn.

Saturn is giving me some problems.

For the last week, I've tried imaging with my DSLR camera to no avail. All I get is a white blob on the image.

I know the telescope is ok, as through the 20mm and 15mm lenses I get a crystal clear image.

I've tried every exposure time and ISO setting I can think off, but the prime focus direct mount method just doesn't work with planets.

I decided to grab my old £30 webcam and tape it to the Cannon T-ring adapter.

After finding some free webcam software, to my surprise, I managed to get an outline of Saturn.

I have to say I am pretty chuffed to even manage an image of this resolution and feel like I've succeeded in my goal, even though the image isn't that clear.

I have seen some threads on this site stating that webcams and CCD cameras are better than DSLR cameras for imaging planets. I am starting to believe these statements are correct.

Anyway, heres the image I managed to get with the cheap webcam. I think I may have to invest in a CCD camera in the future.

I know that this surely is not the cause since you seem to have everything in check but ,... When was your last collimation?

I have had the same problem with my refractor and the only way round it was to put a diagnol on to get the focus on the camera. With the SCT it is no problem, straight on, focus and shoot.
