I started in daylight.
Aimed at a distant object.
Covered most of the frontlens (70%)
Used very short exposure (about 0,1s)
And could then calibrate for focus and a parfocal eyepiece.

Ämne: [M]: Problems with 216XT


I took advantage of a clear night and the full harvest moon to try out my
216XT for the first time.

I followed the CCD tutorial as described in the manual, using the "scotch
tape" method to achieve focus before attaching the CCD.

All the images were nothing but noise. Mostly like 50 vertical white lines
about a pixel or two across. Sometimes nothing but black, but pressing the
left/right arrow keys a couple of times would display solid white on the
right 1/2, and solid black on the left 1/2 of the image. Nothing even close
to an image.

I tried subtle focusing in and out many times, but the images were always
pretty much the same noise.

I had essentially the same results using MaximDL and PictorView.

Any ideas? Just symptoms of poor focusing perhaps?
