The ability to adjust the primary mirror is built into the lower section, and can be adjusted while looking through the eyepiece. It is performed once after each assembly. The adjustment of the secondary mirror is very easily performed also. The distance between sections is kept constant on all sides when Joining with the poles. I use an 'Astronomical Story Stick' when setting the distance between sections.

There is a black nylon shroud that wraps around the assembled telescope, which is used under all circumstances. It is used at night even in Northern Vermont.
Tools I Have Made: 3 Mallets, Layout Knife, a 1/8 inch Skew Chisel, a 1/4 inch Skew Chisel, Miter Box, 1/8 inch chisel, 3/32 inch chisel (from 3/32 Champion punch), Tool Cabinet
