The Destiny curved vane spider and 2-speed 2" crayford focuser. |
|
A small 1.25# counterweight
is affixed to the center of the mirror cell. This helps keep the
rocker box short and closer to the ground, adding to the
stability of the telescope.. |
|
I always include a mirror
cover with the telescopes I build. |
|
The telescope assembles and
disassembles without the need for tools. |
