Now for the last shot. this shot shows the detail of the deck. The dressing on the side covers all the joints and gives a completed look to the deck. It is a 6 x 2" fascia board. Mitred into place. You can also notice that the deck is completely isolated from the pier. Most important that the deck should not touch the pier. Any movement on the deck would translate into the pier. The pier concrete block can also be seen and that too is isolated from the surrounding paving and concrete. This means that there is nothing that will vibrate the pier as I get up and off the deck during long exposures.
Now as for rain. The scope is currently being double tarped of a night time, however there are plans afoot to enclose the entire area with a sliding roof onto the pergola. Failing that, when the scope is fully aligned to my satisfaction I will take the scope off the wedge; leaving the wedge in place and aligned to the pole, and then the scope will be put in its case. This will provide and easy setup as I only need to bolt the scope back onto the wedge and astrophotography can commence as soon as the scope cools down.
The gaps in the decking will allow rain and water to easily pass through and the entire deck is constructed of permapine so that it will not rot quickly.
Now for your comments and questions. Many thanks for following this project.
