I don't know exactly what you're asking hah, is it just general tips on shooting long time exposure? I can only say make sure you get the camera as steady as possible. Any slight movement will ruin the sharpness of the image, sometimes even by pressing the shutter button. Good combo is to mount camera on the tripod, and use the self timer that way there's no touching of the camera when it's taking the shot. BTW how long is it? I had an old cheapo HP that allowed 1s, 2s, 3s, and 4s.
