Observatory Construction - Interior

The walls are fastened to the floor using two 3/8" lag bolts per wall section.

A 68" tall x 10" diameter pier replaces the existing smaller pier.  Nine inches of the pier is below the observatory floor.  This gives me a 59" tall pier within the observatory.  Coupled with the height of my mount, I should be able to view to within 2 degrees of the horizon.  I requested a flat pier top in which I drilled and tapped three holes in a bolt pattern that matches my mount.

The mount is attached to the pier using 3/8" stainless cap screws.

At this point, I couldn't resist setting a scope on the mount and see if all my figuring and measuring worked out.  I am happy to report that everything fits as expected.

On to wiring...

Initially I fastened all the wires, controls and power cubes to the pier with cable ties.  It did not work well and looked horrible.

For my next idea, I took an unused CD rack, cut the shelves, the top, and the bottom to fit around the pier and used 2" wide VelcroŽ straps to fasten the rack to the pier. I fastened all of the bulky components to the shelves using VelcroŽ or cable ties.  I ran the wires through ribbed tubing and ran the tubing through holes in the shelves to the various equipment.  The south side of the pier is shown at right.

A word about the flooring...  It is a conductive mat system.  During the summer I noted a static charge could build between the synthetic decking and the pier.  At times the discharge between me and the equipment would halt an imaging session.  Since the mat has been installed, I have not experienced any static shocks.  I am hopeful the static problem is resolved.

The rack straps provide a handy place to attach controls.

Now all of the hardware is connected and ready for testing.
