I am looking for some replacement eyepeices and lenses for a Tasco Luminova 40076420. Any help would be great. Thanks

About $120 dollars-

I would not purchase this telescope. The focuser is plastic -- not metal, and the tripod is small and shaky.

The large cap-- the small one is used to reduce the aperture of the scope -- no one ever does that. Take the entire cap off.

This is a small reflectro style telescope. It has a mirror in the bottom. The focuser is on the UP end of the telescope.

Like the picture on your question.

This is a reflector style telescope the focuser is on the FRONT of the telescope, the mirror is the BOTTOM of the telescope. All astronomical telescope show upside down images. It's normal.

A manual will not help you-- just go to any well stocked hardware store and buy replacement nuts and bolts, in stainless steel. Tasco will not sell you these parts.
