PeterCPC Posted August 29, 2020 Share Posted August 29, 2020 You would only normally dither long exposures and for that you need to be guiding. Peter Link to comment Share on other sites More sharing options...
david_taurus83 Posted August 29, 2020 Share Posted August 29, 2020 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. Link to comment Share on other sites More sharing options...

Seelive Posted August 29, 2020 Share Posted August 29, 2020 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.

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.

If so, then you may be able to guide using PHD and dither that way. So your right, more gear needed. Link to comment Share on other sites More sharing options...

Atreta Posted August 31, 2020 Share Posted August 31, 2020 (edited) 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.
