Need to create an ultra slow panning device

I need to create a camera panning device which can take around 4lb of load.

It will work like this
The camera is mounted on the axis of the motor which is kept vertically.
The motor slowly rotates and the camera moves with it.

Now I need very very slow motion
So I see this
robotshop.com/en/tamiya-planetary-gear-box.html

This is 400:1
This comes to around 10,000/400 = 250 RPM
This is too fast
I need one rotation every 10 hours

Do you have planetry gear boxes (without motor) which I can mount in series
So I can be
this 250rpm motor followed by 3X100 reduction gear boxes?

For my load and application, what do you recommend which can be slightly programmable.

For example I can choose
1 rotation 1 hour
1 rotation 2 hour
1 rotation 5 hour
1 rotoation 6 hour
1 rotation 10 hours

So I would need to mount multiple 4:1, 2:1 and 400:1 100:1 gear boxes to the single motor.

The product you specified is really the only gear box where you can mount multiple sections to get a very high gear down. Note that mount two gearboxes together (you just need screws which are long enough to hold all sections together - consider threaded rod). Therefore you can have four sections of 4:1 and four sections of 5:1 = 160,000:1 gear down. This translates to 0.05rpm = 3 revolutions per hour. If you really need one rotation for every 10 hours, you can consider adding even more gear downs and/or using a motor controller to reduce the speed. Another consideration would be rather than having the motor at the center, it can be connected to a small wheel and rotate a larger disk on top of which sits the camera.
