Now that the painted main
tube and dew shield have both cured and out gassed sufficiently, it
was time to start assembly of the VSC/ SAO Carton 100mm f/13 "Mary
Dawson" refractor OTA. As you may recall, the Crayford focuser
adapter was installed prior to the main tube's finishing process. So
outside of the installation of the flocking, we can say that it was
the first component to be installed in the assembly process. But the
next components to be installed was the front/ rear cell assembly,
which also incorporated the Carton 100mm f/13 objective, as seen in
the image above. The rear portion of the cell was attached to the
main tube using three grub screws and sat into small divots. Snugly
screwed into place the grubs held the rear objective cell firmly and
securely to the main tube. The front cell containing the Fraunhofer
doublet was then attached to the rear cell piece. Collimation will
occur later once the focuser is install and the telescope is ready
for testing prior to First Light. |
