MY ORIGINAL BACKYARD MINI-OBSERVATORY
You have read about this in Phil Harrington's book "Starware" (third edition). This little structure housed a 5.5 inch Mak. My micro-observatory was made of 1/4 inch plywood and is ventilated to keep the telescope cool. Maksutovs are notoriously sensitive to the temperature. This handy little building allowed me to walk out the back door and be observing with a thermally equilibrated telescope within minutes. When I built it, I used carriage bolts with the rounded heads toward the outside to prevent tampering. Inside the wooden structure is a six-inch steel pier buried in sand (for vibration damping) and concrete at the bottom. I got the sand idea from an old astronomy book and it works very well! This micro-observatory was big enough to house a seven-inch Mak or an 8-inch S.C.
THE LATEST VERSION
When I moved
recently I was forced to abandon the previous version of the mini-observatory.
I also acquired a C-8 telescope with excellent optics and a 110 volt clock
drive - the perfect backyard option. I sank a pier, ran the power and built
this version. You can see that it is quite a bit slimmer, more lightweight
and attractive. I used simple screw and glue with lightweight 1/8 inch plywood
and a skeleton of good quality 1x2 stock. (My new neighborhood seems a bit
less rowdy so security is not as much of a concern.)

THE OBSERVING CHAIR
This observing seat folds up, is infinitely adjustable and makes observing much more comfortable.You can find plans for a nicer-looking observing chair based on this idea at Chuck Carlson's Page on the DAS web site or in Phil Harrington's book Starware (second edition).
