The flattener serves as a lens to level the field, addressing the slight curvature caused by primary optics. This curvature often results in less sharp stars at the field's periphery. Also known as a field flattener, it remedies this, ensuring astrophotographers capture sharp stars across the entire frame.

Observing the Sun is always a delightful experience, not limited to solar eclipses alone. The dynamic nature of sunspots, constantly changing in number, shape, and size, offers an engaging spectacle. With sufficient magnification, one can even discern the core and boundary areas of a sunspot—the umbra and penumbra. However, it's crucial to ensure that sunlight is reduced to under 1/100,000 of its normal brightness for safe observation.
