Dithering

How do you dither... Do you need a guide camera to do it.. Thanka

You would only normally dither long exposures and for that you need to be guiding.

If you use APT then you don't need to guide at all. APT can dither the mount for you as long as your running EQMod.

Dithering just involves a random movement of the stars in each image to be stacked relative to the image pixels. It can be done manually just by moving the scope/camera position slightly between each image. If your not guiding and your polar alignment isn't perfect, your half way there, especially if the interval between images is varied randomly.

What equipment do you already use? Like I said, you don't need a guide camera/scope to dither. Bare minimum is a goto mount, EQMod cable and a laptop/PC. Assuming you don't want to do it manually of course.

Does the controller have an ST4 port? If so, then you may be able to guide using PHD and dither that way. So your right, more gear needed.

The handset has a st4 port...

Like  david_taurus83 said,  you don't need to be guiding,  or a guide camera  to do dithering with apt, it can do dithering on its own. But you still need to connect apt to the mount with eqmod. 

To do dithering this way you click on the gear tab, hold shift and click on the guide button, where it's showing guide program you choose apt dithering.
