Primary and secondary mirrors, with spider and cap (REDUCED)
This is a kit for the hobbyist, including the following:

- 4.5 inch (114 mm) primary mirror
- Full mirror cell with adjusting screws
- Secondary mirror
- Secondary mirror holder
- Spider for secondary

In very good condition.

This came from a Meade DS2114 short tube Newtonian telescope. The teeth on the focuser were worn out. As the tube for this telescope is made shorter via a special lens in the focuser, the tube is not of use anymore.

However, the primary mirror is in very good shape, with its entire cell and adjusting screws for collimation. The secondary is in its original holder with a 3 vane spider with screws.

There is a tiny speck on the primary mirror that would not be cleaned. This would have no impact on the image at all.

If you want to build your own telescope, you can get a sonotube, and a focuser and you will be in watching the night sky in no time with your new Dobsonian. Or you can even make your own focuser!

Instructions on how to make your own telescope is abundant on the internet. Here is a good resource:
