Eye Pieces

Before starting in astrophotography, it is recommended to first get familiar with and learn the night sky.  This will help doing Polar Alignments (by being familiar with the more brighter/common stars to align with) and get a general understanding of the coordinate systems involved (celestial equator, meridian, zenith) and concepts like gradients (how things look different high in the sky versus low above the horizon).   Eye pieces are also helpful for collimation and preparing initial alignment of the equipment (such as ensuring any guide scope is aligned with the main optics).  

It can also be more relaxing to just visually inspect objects.  But setting up a telescope for visual (eye piece) configuration is generally quite different than for digital/astophotography configuration: the equipment and balance is different.  Switching between the two generally means doing a re-alignment or re-balancing.

The quality of eye pieces comes down to the quality of the glass used.  There are also aspects like being "parafocal" and how large of a field of view the eyepiece allows.  The "top brand" in eyepieces is generally TeleVue, although there are many other brands that make glass that is adequate.

Most eyepieces are either 2" or 1.25" diameter, and most 2" receivers have adapters to also hold 1.25" (but not the other way around).  The 2" eye pieces are much larger, with the eye piece basically being slightly smaller than a soda can.
