Roll off roof obsy...a fundamental decision to be made
Hello fellow astro dudes!
I'm making a pretty basic, 1 room roll off roof observatory. It will have a gable roof on rollers. The rollers and rail are pretty darn heavy duty. They cost me about 5k (already bought them) and can hold 1500kg each bearing (there are 4).
I'm thinking it'll probably be about 20 square meters plus an outside paved area for visual. I have a lot of space (rural location) so footprint is no concern. Cost however is.
I have a fundamental decision to make: should I make the walls high enough to be able to close the roof without putting the scope in a horizontal position (see photo attached), or should I make the walls shorter, enabling the building to be smaller dimension overall? I would like to view targets 15 degrees or so from the horizon (what are people's thoughts on this? Is this too much to ask or too little?).
My pier, mount and current scope (only a 100mm APO refractor) is 2100mm tall. I'm hoping to eventually replace it with a 12.5 or even 14 inch planewave CDK. So I'd need it to be even taller, or else I'd need to put the pier on a lower footing than the flooring. Any advice would be greatly appreciated, as this is the first thing I've ever made, and my builder, although an absolute legend and expert, has never made an obsy before. Thanks in advance!!!
