Hi Ivo,
In my first images I am using the same gear as I have now for imaging. I have a DOB so initially I could only manage the capture of a number of frame while Jupiter and Moon were moving across the Field of View (Earth Rotation). I would then have to reset the scope back and let it run again through the FOV again. This caused pixels to blur even at high frame rates. Pixels as they changed from one location on the sensor to the other may blur across. Sometime 2 or even 3 pixels would blur together.
Now I have built an EQ platform which allow the planets and Moon to stay in the field of view for much longer. It also allows me to barlow the planet view as well. This can only be done with a stable mount. Opticaly enlarging the image provides more pixel and the pixel blur is sufficiently less. I still get a bit of movement within the FOV but it is more stable.
Jupiter though is reletivley hard as Jupiter axis rotation speed is quite high, so especially with the DSLR if I take too long AVI the rotation of the planet is experienced and then get features blurring. This post images are limited to 500 frames, whereas my webcam can take 2 to 3000 frames in the same time frames. The more frames the better Registax or AVIStack or Ninox can sort the better ones.
One project I am working on for my galery is to make a Youtube video showing before and after frames just to show how difficult imaging can be yet how terrible looking frames can turn into nice images.
