I Bought A Orion 4.5 XT Dobsonian Telescope and its great, but it came with 2 extra parts that i am unsure of what they are for. I read the whole manual and it didn"t mention them. One part is defiantly a lens cap but it has a small whole in the middle. Another part that i have no idea what it is for is a Small cube that has slightly tapered edges... If anyone knows what these parts are for or how to use them please tell me. :)

Youll probaly need to find the part list and check off what you can account for. One of the mystery pieces, Im betting i a collimation cap.

The first i a collimation cap, used for aligning the optic of your telescope, a process called collimation. It is described in the manual. The second i a stop or bumper. Stripping off the paper on the larjest side will reveal adhesive. Attach this on the inside of the rocker box on the front section, so that the tube hit it when pushed vertical.

Enjoy your telescope...it a good one!

The lens cap is actually a collimation cap - you can use that in the process of collimating your scope.
The small cube is very likely a bit of rubber - with a bit of adhesive on one side - it is a bumper that you should put where the bottom of the tube would bump against the front wall of the lazy-susan/mount.
