Aspect Ratio for Canon DSLR Live View

When I use my Canon 600D on live view through my 150mm F6 reflector telescope for planetary imaging , should I set my aspect ratio to 1:1 in the menu

Does shooting in live view default to an aspect ratio of 1:1 ??

There’s nothing in the Canon manual that answers this question directly

All the DSLR Astro sites and blogs mention you must shoot with an aspect ratio ( pixel resolution) of 1:1 if imaging planets and the moon

It’s currently set at 3:2 and I’m getting reasonable images of Jupiter and Saturn through a 4x Powermate

I haven’t done any stacking or processing as yet

Appreciate any advice on this
