Scott and his crew recently built a 12'x16' two-pier observatory for me. It went up pretty quickly, and looks very nice! I can't wait to use it after I complete the details (custom door, stain the cedar clapboard, attach items to the piers, add electrical power service, etc.).

Here's a sketch of the floor plan. The scopes are oriented in the Astro-Physics Park 1 or Park 4 position (the OTA is parallel to the N-S axis).

The holes for the deck foundation are being made w/a power auger and a post hole digger.

The trusses, for someone else's observatory (in the same neighborhood), were delivered to my site inadvertently.

After the first foot or so into the soil, the heavy artillery (jack hammer) had to be engaged.

The deck was framed for two piers now, but I decided to frame out a third in the middle, in case we decide to use 1 centrally located pier in the future.

Imaging tests in this location suggested that a drop-down South wall might be useful. M8 was about 15* to 18* high when this rough draft image was taken (AP Traveler, FLI ML8300, Astrodon Gen2 Luminance filter, 6x10 min subs, no flat field calibration).

Here's the drop down South wall.

Did I use a fisheye lens, or did Scott at BYO use curved lumber . . . :grin:

Looks great! What was the build time from start to finish?

Several months before the build, I evaluated the site for it's imaging potential with an AP Traveler.

BYO built a 9'6"x11'6" observatory for me in Nov 2012. I ordered the drop-down south wall mainly so I could entertain myself visually with Canopus and Omega Centauri. But it has been most useful for quickly bringing the interior down to evening temperature after a hot summer day. I don't see where you've stated the location of your observatory, but it looks to me like pinon-juniper woodland somewhere in the high country of the Southwest.

Regrettably, it's near the East Coast, with mediocre seeing.

About 5 days. It would have taken a day or two less if the ground contained less fractured rock and the local lumber yard had delivered the supplies to the proper location (it dropped part of someone else's load to my location and some of my stuff to the other place).

I should add that Scott, Robert, and Don worked in a highly coordinated fashion. They didn't need to discuss much, as they know how each other works. When issues arose, they quickly figured a solution.

Scott normally builds stairs if needed to gain entry into the observatory. After he and I discussed the fact that the door swings out (which dictates the need for wider steps), Scott suggested adding the deck under the RoR posts and beams. It was a nice solution.
