Can someone advise on the best way to take pictures of stars.

I appreciate that my camera may not be good enough as it can only manage 8 second exposures at max but what other settings make for good clear pics of the stars.

I took a photo of the Plaides and ended up with only a few blue dots of light and it was not at all like it was through the eyepiece.

I would also like to know how you stop them coming out as very blue blobs of light, or is this just my camera.

Am I being unrealistic.

Thanks.

Have you got a Black and White setting?

Try all sorts of settings, that's the good thing about digital you can take hundreds of shots and only keep the good ones.

All I can say about this from my experience, is that more sensitive the ISO the more light pollution you pick up. It really is trial and error. I try to use 400 or 800 as I've found I pick up less pollution.

Yes, I've found the light pollution problem too. Crux of the matter is a less sensitive ISO setting takes longer to take an image, but by definition a more sensitive ISO setting will pick up faint signals such as LP with greater efficiency, reducing the contrast between the faint and bright signals.
