SAO 127MM 'BRIGADIER GENERAL RICHARD PIERCE' REFRACTOR OTA COMPONENTS & ACCESSORIES
|In constructing the OTA for
the SAO 127mm 'Brigadier General Richard Pierce' or BGRP refractor OTA, I
applied the same principles and techniques I used in building my 10" f/5.6 Newtonian.
Innovation, durability, performance, and cost effectiveness. The OTA's
collection of components consist of the mounted 127mm f/9.4 fully coated
achromatic objective from SurpluShed, the
raw 5" O.D. x 48"
length x .073" wall and 6" O.D. x 12" length x .083" wall tubes from
Hastings Irrigation Pipe
Company, and the focuser came from a Meade 127ED refractor and was donated
by Richard Pierce (for
which the instrument will be named after). The baffles were
constructed from old CD's, 1/4" plywood and dowels. The cradle rings were cut on my
band saw from 3/4" teak wood.
And last but not least, the 8x50 right-angle finder was donated by my
colleague Gary Barabino. In this section, we will go into a bit more detail regarding these
components. If you have any questions
