Spent a couple of days making a custom equatorial wedge for my Nexstar 11 GPS and trying to attach wheels to it to make it portable when I had the idea of converting the plastic Rubbermaid shed that I already had in my backyard into an observatory. I have seen others doing the same thing and had some metal heavy duty hinges laying around so I made this observatory in my backyard in one day. I can tell this is going to save A LOT of time with setup and polar aligning. Since setting up the observatory, I only spend 1-2 minutes setting up my laptop instead of a minimum 30 minute setup and tear down. That means more imaging time. I successfully autoguided my first 10 minute sub with this with an off-axis guider. It was amazing how easy and nice it is, without having to polar align it everytime. And it cuts down on wind A LOT! I am very happy and excited about this.
This is a fliptop type observatory. I use a fabricated rod to move the roof. It takes about 15 seconds.
