That's what it's called,...

There are no lenses included with this. This is just the mechanism that attaches and goes through the telescope and houses the gear and crank to raise and lower the eyepiece itself. This would be considered a replacement piece but unless you have a compatible telescope which happens to need this  exact piece, this will be useless to you. If you need any more information feel free to message me but please confirm this item is what you need before ordering as I do not do returns
