If you do, is it because you had your head up for too long?

that's normal especially if you are using a 10x50 or higher mag bino.
all that non-stabilised views affects you much like sea sickness. the solution is to put your bino on a tripod...

Other possibilities:
1) Miscollimation
2) Focus on left and right sides not optimized for your own eyes

Looking at skies with head tilted back from a standing position for prolonged period is not recommended. It places tremendous stress on the neck. It has been known to narrow arteries that supply the brain and cause dizziness. Severe narrowing of these vertebral arteries can even cause strokes...

Some ways to reduce strain and enhance viewing...

Note that images will be upside-down with the bino-mirror combo.

To prevent dizziness, don't (1) stand up & (2) crank your neck backwards while viewing through the bino at the sky! Always best to sit on a reclining deck chair or better still, lie down on the mat with a air-pillow.

Or you can support the bino on a tall tripod.

There is one or perhaps a few companies that make such mirror mounts with binoculars. It is sort of like 'microscope' way of viewing the universe. Find it a bit weird.

Advantages would be that it is very portable, can be placed on a table and will not cause too much neckaches. The disadvantage would be that the mirror will dew up in no time in our climate unless there is a dew heater on it.

I don't think a stable table goes well with the concept of portability...
