Have you ever wondered if the Max 20" will fit in a particular dome or roll-off roof observatory? If you draw your building / dome structure and use Google SketchUp, I have an approximate model of the telescope on a pier. From SketchUp 8, go to Files/3D Warehouse/Get Model and search for Meade Maxmount (or see the attached file).  The CAD model has 5 main components (see below) that allow you to re-orient the mount and scope.   If you learn/know SketchUp, you can start from my sketch and add more details or change the pier height, etc.

The attached file has the latitude set for 35 degrees, so your adjustments should reference from that starting position.  It is a rather simple model, and is probably only accurate to an inch or so, so please don't use it for high precision or critical dimensions.  It was based off the three-view on Meade's Max web page, and is the first time I ever used a CAD program, and it is far from perfect.  You've been warned!

The SketchUp 'components' allow re-positioning and re-orienting to apply to your location and situation. As it sits, it has: a 22-inch tall pier (you can push/pull to alter the height); the Pedestal Assembly (no usable adjustments); the Right Ascension Assembly with a pin thru the Pedestal to reference LATITUDE adjustments (nominally set to 35 deg); the Declination Assembly with a pin thru the RA Assembly to reference HOUR ANGLE (R.A.) adjustments (nominally set to 6 hours); the Outer Tube Assembly with a pin thru the Dec Assembly to reference DECLINATION adjustments (nominally set to 90 deg). Be sure to select all of the components 'above' the one you are adjusting so any adjustments will affect the appropriate components. For ex, to adjust the latitude, select the telescope OTA, the Declination, and the Right Ascension assemblies to have them all pivot as you adjust for a different latitude.

Enjoy - Mark
