View the Moon without "zooming" due to Earth's radius

Asked by cosmogoblin on 2019-08-06

I'm trying to create a video of the Moon over a month. I've turned off the ground, atmosphere etc, and selected equatorial mount.

This works perfectly except for one thing - over the course of a day the Moon increases in apparent size, zooming in and out, due to the Earth's rotation changing the observer position by 12,800 km each day.

I tried setting the observer's elevation to -6,400 km, but this only goes down to -2,000 km.

How can I view from the centre of the Earth?

Seconds after posting I realised the answer - set observer location to the north or south pole (I was previously using the equator). This means the distance travelled per day due to Earth's rotation is zero. I tested this and it works perfectly.

I'll leave this here for anybody trying this in future.
