Dark Arts Observatory - Brockport, NY - Skyshed POD XL5 with iOptron iEQ45 Mount
Scopes: C8, C5, SV110 ED, EON-72 ED, ST 80, ATRC6, Megrez 90
NW Mass, inches from Vermont
(well....it used to say that.....)
Quote:I'd vote for a pod-type obs......with that open view, you've got plenty of sky available, and the logistics of putting in a pier, and keeping gear nearer the ground, are much simpler than building a 2-story pier in the workshop
Quote:There is no one in the area I think there are one or 2 contractors on the island for example. The plumber we hired is also the electrican on the island and the fire chief!The point of building onto this building is its higher then a new building. I have a 6x8 at home and it was hell to build but functional.The workshop has its own circuit it should be more then fine for a camera mount and computer plus a few other minor things. After Allan's power tools plus a large stereo were previously used. Even if it has to be upgraded that's cheaper then starting from scratch.
Quote:So what do you think it would cost to cut a hole in the roof and do something like this
Quote:I have built the skyshed. I have a 6x8 roll off now. I found it very difficult as I had no experience. I certainly would do a better job the next time, but the building at ground level would face a lot more obstructions and the cost of building a comfortably sized one say 10x10 or even bigger would likely be more then cutting a hole in the roof and adding that small addition. When factoring in the dome I think that would be the only thing that could push it over.
Not even a ballpark figure? $500? $5000? more? I do know labor there is cheap the plumber charged just $40 an hour for labor you'd never find one anywhere near that cheap here. I can do a lot of the other fixing up. I just want a professional to cut the roof and build the little add on. I probably will have to wait until spring / summer to get a quote. Most people there don't even use the internet so it's not like I can email them pics..
As far as worrying about resale factor that's not even a consideration. They will never sell the place and even if they did I would be first in line to make an offer. It also would not put a serious dent in the resale value. The waterfront property on 3 acres with a nice 3 bedroom house that needs relatively little work cost less then a 1 bedroom condo that you'd be lucky to get a 4x6 balcony of outdoor space would cost here.
Quote:My note about expanding the attic was a concern that the scope might not be usable from certain angles.

If the wall that splits the attic is close to where you'd need to be, it'll be there even if you raise the floor a bit. I can't tell from your photos if it'll be an issue, but take careful measurements before you cut one piece of wood.

Quote:Having a 10" diameter pier that tall would be more too much like a tuning fork. I think vibrations would be a problem. Keep in mind that contractors are concerned with strength, not vibrations. Concrete is incredibly strong in compression and a tall, 10" pier will support more weight than you can imagine. But if you whack it, it will likely reverberate for a while.That's why the cinder block base makes more sense. It's a lot larger and provides the mass you'll need. Another option is to go with a larger sonotube, like the 14" (or more) that smtguy suggests, up to the floor of the observatory. Then go with 10" from there up to the scope, or you could use a steel pier at that point. You want the part of the pier that is just below the mount to be relatively small to minimize the chances of a pier strike when the scope is moving.-Dan
Quote:He seemed to think the cinder blocks would be a lot harder to work with, but that is probably okay for me. I plan on doing the pier myself,
