A handy removable eyepiece rack can be attached to the StarBlast 4.5 base to provide a helpful storage spot for unused telescope eyepieces. The included Orion EZ Finder II reflex sight makes aiming the StarBlast 4.5 'EZ' once a simple calibration process is completed, so you can precisely point the reflector anywhere in the night sky. We've even included a simple collimation cap to help maintain optical alignment of the StarBlast's mirror optics. An included dust cap fits over the front of the telescope to prevent dust buildup.
