On a microscope what objective do you start with?

When using a microscope, you typically start with the lowest power objective, often the 4x or 10x objective. This allows for a wider field of view and makes it easier to locate your specimen. Once the specimen is in focus at low power, you can then switch to higher power objectives for more detailed observation. Always ensure to adjust the fine focus when transitioning to higher magnifications to avoid damaging the slide or the lens.
