The eyepieces that come with the telescope are modified Kellner’s. They are OK for the beginning. We strongly recommend changing them with Plössl’s to increase the quality of the image. The difference will be huge.
The red dot finder is a standard, cheap model among beginner telescopes. It works without any problems, but a 6×30 finder scope would make things much easier.
The prism corrects the image but dims it quite a bit. We recommend it only for terrestrial viewing.
