Carol the main part of the footing is finished in that image the main pier took all ten of those bags + another half bag I already have.
I have the walls up on the building and the outriggers and will post the images of them later after I resize them.
Have to get out there now and get busy as the Duke would say,"We're Burning daylight!"

Looking at those sacks made my back hurt! We'll be anxious to see more photos of your build!

Here is another shot of the build.Walls are up as are the outriggers and roll off roof supports/4x4 posts. The steel angle iron,for the roofs v-casters,is mounted on the top plate and painted with Rustoleum flat black. I also painted the floor of the OBS last early last night as it was suppose to start raining this afternoon,it did and is suppose to continue on and off thru Saturday.

Nate,Thanks for your reply, both my wife and I are feeling much better. As far as getting help from the kids,yeah right ,like that's going to happen. Honestly though,I prefer to work by myself unless it is way to heavy for me to handle by myself. My stepson did get the footings all dug for me with his Bobcat loader though and I was very appreciative for that.A case was waiting for him afterwards.
I will tell you though even though I had just built an observatory last year at a friends house,75 miles away, I kind of forgotten how heavy those 2"x8" treated boards can be let alone with 3/4" 4x8 plywood. I worked my tail off on that OBS yet this one seems to be really kicking my tail.

Nate,I had a few other things that had to get done today before the sky decided to fall. So the only 2 things I got done today were installing a window and spray painting with rustoleum flat black,the angle iron after it was installed.

Thanks Nate and Norm for your comments. All I got accomplished today was painting the siding for the OBS in my garage. Been raining most of the day and suppose to continue on and off thru Saturday.I had 11 4'x8' sheets and it took 1 1/4 gallons of Behr all in one primer and paint to get the job done. Good thing I had the extra 1/4 gallon left over from painting my woodworking shop a few years ago. The cost of paint has really gone up in the past couple of years!

Tim, it's really coming along nicely. The first night you view from your new observatory, you will forget how heavy those boards, etc. were! It will all be well worth it!

Thanks Carol,I appreciate all the comments of encouragement from everyone on the cloud.The most difficult part for me is coming up. I plan to build a Hip roof for the OBS. Now I have never built a Hip before and since I have already ordered and received the red steel roofing,there's no going back and building a gable end style roof.
I am using 2"x6" boards and making it a vaulted ceiling so as to have plenty of head room for the scopes.

One thing I really wish I had done,was had my 10" LX200 scope here when before I had poured the pier. As it stands now,The pier height from the floor up is 48 3/4" tall. I had planned to make the wallsto a 6' height yet after pouring the pier,had to go with the 4' height. I am 6'3" tall yet and with the walls now set at a height of 86 1/2", so that the one scope stays within the OBS,I am going to have to build a platform around the pier base so I will not have to use a ladder for viewing lower in the sky. I feel so much like an idiot for not having checked the height of the LX200 10" at zenith before pouring the pier.

There will be times when I want my CR150 HD 6" Refractor mounted on the pier ,so the height of the pier will be an advantage,yet will still have to add an additional pier extension to it so I am not on my knees to view thru it. There seems to be way too many variables to think about when building this permanent structure.

The one main thing to consider for me, was and still is aesthetics of the OBS as far as my wife is considered. She has stated the outrigger portion looks like a car port. I will have to think of something to kind of disguise or otherwise enhance the looks of that end somehow. The OBS is next to the area that is our vegetable garden. In fact,the support posts are partially in the garden.

I have a question for anyone that has used steel roofing for their OBS. Normally when steel is used for roofing on a pole barn , you place purlins on the trusses and attach the roofing to them.
I am using 7/16" OSB plywood for the substrate on the roof then placing the steel on that.
The roof will have a 3/12 pitch so as not to block as much of the view when rolled off.

There are 2 main reasons for the OSB sheathing in my opinion. One reason is without it,using purlins,condensation will form on the underside of the steel as it has on a previous OBS build I have done.
The other reason in my mind, at a 3/12 pitch,with snow on the roof, OSB will strengthen the roof.
Now, Is there really a need to apply roofing felt prior to the steel? You definitely would if using asphalt shingles,yet is it really necessary for steel?
Stupid question Right? Of course, the more protection the better. Just thought I would throw that out there and get some insight since I have only used this type of roofing once before..

yes as I think you will still get condensation on the underside of the steel roofing panels. I used steel roofing panels , plywood, and used a self sealing membrane from Home Depot as I didn't want to take any chances of leaks

Yes use the paper. Like Norm said, you still want the vapor barrier. Another good reason for the OSB on the roof is to strengthen the structure, especially if you motorize it.

Thanks, Norm and Scott for your replies. I will definitely use either 15 or 30 lb tar paper for added protection.

Tim , I think it was you asking about a seal to keep dust down on a other Tread for your ROR Obs, This would be something to look into , Because of the radius of My Dome I could Not get it to work , But this Stuff could be used on All Sides of a ROR Obs. www.Memtechbrush.com
