Acuter Digital Imager

Got a new toy last week the Acuter ccd camera. I took some photos the otther night or Saturn and as the attached images reveal the focus or the image is a little blurry. Now I had the fosuc on my meade spot on and this is the result. I had previously looked at saturn with my 26mm and it was a very good view. i tried with the 9mm and this was also good but a littly hazzy.

The camera has a I believe a barrels that attach to the camera it has a lens inside which I believe is a focal reducer and the other is a short tube with no lens. the photos are with the long lens. I did try the short barrel without a lens however there was no image at all with this.

Does nyone have the same caemra or have any hints or can tell me where I went wrong or is it just the conditions and it wasn't me ?

thanks in advance.

I attach the pdf link for the actual camera

The lens in the barrel is in fact a balrow lens. It actually increases focal length.

When you remove it, it will produce a smaller image on the CCD, but it will be brighter, and clearer than thru a barlow. But for planetary work, the barlow might be needed to get some size.
Focus is at a different point when you use the barlow, so maybe use it on the moons edge and try to focus and see where the focus is. You may need to reduce or increase the spacing from the telescope if there is not enough travel on the focuser.
