Yesterday, it seemed like there were poltergeists in my equipment. I cannot remember ever seeing my guiding so unstable as it was yesterday.
Have you ever seen guiding errors looking like this?

Tonight - all is perfect 🤷‍♂️

The only time I get star shapes like that is when something bumps into my mount, causing it to shake very quickly, creating those star streaks.

Clearly you caught a group of UFO's in formation! It's the only logical answer.

The boring answer could be wind, especially given your pixel scale and the length of your Newtonian.

100% its Aliens. Do you live in NJ by any chance?

No, but its very respectful of the aliens there to apply the standard FAA regulation navigation lights to their spacecraft!

I'll get this as well from time to time. If it happens, it's usually just 1 or 2 frames and the rest are fine.

My guiding works fine otherwise, so best I can tell is that it's a random gust of wind.

That’s also where I have “landed” - wind gusts.
Can’t seem to find any other plausible reasons for this for now.

Have seen something like that for a few times, all because of strong wind.  There may be nothing wrong (other than wind) with your system.

It's wind or a random night critter…

Its wind, my guiding looks like that when wind kicks up above ~7 mph

I have just never seen my guiding behave like that in wind before. 

But I did have gusts the other night. 
Furthermore I have raised my scope 20 cm in my “astro tent” so some of the dew shield will now be above the top of my enclosure in some scenarios, so that might have shown up as “new”behavior for me 😛

Considering lowering my setup again, but the added height has given me some extra time closer to the horizon 😀

better to accept a half hour less imaging time having the scope lowered, than to lose possibly a lot more than that with random gusts of wind catching onto your dew shield.

Yeah - but I actually lost 2,5 hours of data. But after spending more time investigating I am beginning to suspect that something else might have been strange as well. 

I can see that the data before and after the meridian seems strangely off in how the images are rotated. 

I think I will write off this night as being haunted by aliens 😂

Do you have through the mount cabling? Might be causing a small bind after the flip?
