I know it wouldn’t be great, but I’d imagine it could slightly improve images for small setups on something like the skyguider pro.

That does not improve the situation at all. You want the mount to track well _during_ the exposure. The main purpose is to take longer subs. You can go that path and implement dither. That is intentionally moving the mount in a random pattern. After star alignment and stacking the hot pixels are no longer in the same place and can be sorted out. This needs both axes to be guided. A skyguider pro is a single axis device. So probably no use at all.

Thanks. I really didn’t think that one through. Of course autoguiding is only relevant during the exposure. The only benefit I could see is to keep the same image in frame so it doesn’t crop during stacking.

If your image is shifting that much, you need to address whatever is causing the improper tracking. If in an hour worth of exposure you are having framing issues, you really need to direct the attention to the source rather than looking to guiding as a solution. Never hope that correcting after the fact will be preferable to not making the mistake in the first place.
